How long have Delkevic been selling these?
[attachimg=1]

I could not find it on Delkevic - listed on ebay as you say Julie.
I was hoping it was in Stainless but reads as Chrome.

Just had a look,
Very comprehensive,
Rubber link tubes, brackets
All gaskets
Seems very good deal,
I am certainly interested

Lot cheaper than David Silvers
-
I wonder if they might make a SS version soon - I'm guessing the silencers would not have the same detail as the chrome one.
It will be interesting to read when a member has bought one & read if they fit easily.
-
Thats less than i paid silvers for a set 20 years ago
-
They look great, makes me want to buy a 500.
Cheers

Unless I have it wrong I did not realise that the front pipe & silencer are one piece - that must make maufacturing pretty precise to make it fit.

Yes Ted, thay are all in one piece, same as 750's.

For what it's worth.
I have heard that the pipes the produce for the Suzuki Gt750.
Fit perfectly & are well regarded.
Regarding Chrome. I believe they are plated by Niphos in Crewe. A company I have used many times over many years. With excellent results.

Tempting indeed...
Doesn't show/tell if down-pipes are double walled, nor does it give any noise levels...
So the question if I could ever pass an MOT with those over here is pending...
Likely requiring are very forthcoming (blind and deaf) inspector... ;D

These look very interesting and certainly look the part. The photos might be slightly misleading the one shows all exhaust clamps brackets etc, but the write up states that they come complete with gaskets.

I had the system on my gt750. Well made but did not sound the same as oem pipes though this could be due not having years of two stroke soot coating the innards. I’m interested but would like to have some feedback on noise level/ tone before taking the plunge.
-
Definately a game changer imho. The pipes on my 500 are ok and not due for a replacement and more importantly .... original. Wonder what prices are on the continent.
-
There is an Italian site that sells the 4 into 4 system - they occasionally have discount offers.
With a UK seller returns or damage is much easier to resolve imho.
-
Delkevic have confirmed the front pipe is twin walled - I've ordered a set for my 500.
-
very tempted by these, let us know what you think of them Ted.

Nice one Ted. Looking forward to hearing about your experience with it. Price is now just ouch rather than no chance !
-
As I have no brackets it was a lot cheaper than buying a complete system from DS.
I will not be fitting the system until I have the wheels in place.
I will report how easily it fits in the spring.
Update:- I've been told to expect delivery on Thursday
-
I’m going to order a set next month.
Think I’ll tell the missus it’s a very reasonable £250, Just won’t tell her I need 4.

Firstly thanks to NJ for finding these recently listed systems by Delkevic
Early observations are they are well packaged with all the fittings - so far so good.
The finish looks good too early to comment on the quality of the chrome - time will tell.

I might be totally confused here but I thought I meet you at Crich Show a couple of years ago - you had a very tidy Yellow CB400 IIRC.
I chatted with you for a few minutes I thought you were a retired vicar who had a 400 - you assured me you were never a man of the cloth but soeone on here is!!

It's probably John, Hondrc166, he has a yellow 400/4 and goes to Crich each year.
-
That looks a bargain.
So you get everything, even the finned exhaust clamps.
-
Yes the clamps look much better than my old ones - it certainly looks good value compared to Busso & DS systems.
-
Impressed with that Ted, wasn’t sure if everything would be included. Be very interested to hear of the fit! Unfortunately I have a new set from DS acouple of months ago.
-
I had stalled the exhaust purchase until March 2024 but due to the Delkevic launch price I have managed to afford them this month otherwise it would have been a DS buy.
Just a case of serendipity tbh.
-
Launch price? Does that mean the price is going to go up soon?
I don’t really need one for at least a couple of months but I’ll get it now if the price is going up.
-
Launch price is just a guess really - I just decided buy it now whilst the price is acceptable.
-
Delkevic stuff is good isn't it, I was very impressed with my 550 exhaust when it arrived at Christmas. It is owned by DK isn't it?

Mr Google says DK has them made in China in a factory DK owns - as are a lot of things sold in the UK & USA.https://www.thekettleclub.com/magazines/94-flex-flier.pdf

Always wondered, what is the purpose of the link pipe between the top and bottom pipes near the ends?

Its there to make fitting bloody awkward
-

I know in the late 60s, Triumph linked the exhaust on their twins,
I think to increase the expansion capacity, to help breathing and maybe making quieter,
The Honda ones are similar, but appears to be much further along the exhaust pipes,
Does it make a difference?
Hopefully those with more information will explain

IIRC are such "balancing" ports intended to increase low end torque... dunno if this also applies when they're that far down the line though...
The ST1100 has them in the down-pipes, right below where they attached to the heads; would look odd on those /4 engines...

I ordered the exhaust over the phone yesterday. I jokingly said to the lady at Delkevic I’m dead when the wife finds out.
She replied that they’ve already had a guy in this week to collect in person and pay in cash so his wife doesn’t know how much he’s spent.

Wipe your fingerprints off the phone to remove any evidence of wrongdoing Steve and when it arrives just say it fell off the back of a lorry.

I'm not asking for that reason as not many replica exhaust systems for old bikes have that type of info stamped on them anyway. Im really wanting to know if they have Delkevic stamped on them.

I’ll check them later on and let you know.

That's the one thing I don't like about my Delkevic, the etched logo ruins it and it can't be rotated out of view. Different exhaust than this discussion is about obviously.
-
Just checked all 4 pipes, no markings of any kind.
FYI, kit comes with everything you need. Brackets, bolts, copper sealing rings, clamps and collars.
Even the rubber bump stops for the stands.
It’s a lot of money but a hell of a lot cheaper than the other source of these.

CMS are in the process of sourcing and sell 400/4 systems Tim, their advert keeps popping up on Face Book.
-
The repro 400/4 system I purchased from DSS back in 2017 was an absolute nightmare to fit, it kept fouling on the sump. I had to use brute force in the end to slightly bend the pipe to clear it. I hope any new ones CMS may stock in the future are better quality!

The further down the line they will enhance performance in the high rpms, at least, they are supposed to. The ones closer to the head are to increase mid or low end torque. It's been a long time I learned this, but the source was definitely trustworthy.
-
Reports back from someone in UK that has now fitted the system is that the fitting is pretty easy and straightforward and they fit very well.

That’s good to know, I’m not ready to fit mine yet.

Assemble everything loosley then work front to back tightening evenly
-
Found it
"The key to getting the 4 into 4 system to hang right is to fit them with the end joints missing at first. Fit the lower one first, remember that this bracket goes behind the frame hanger, fit the manifold clamp and collets very loosely so the front can still move around but can’t fall. Now fit the upper exhaust, bracket now goes in front of the frame hanger, so one each side, fit the footrest loosely. Look at the balance pipe at the rear of the exhausts, they should be directly in line with a small gap between them. Now move the pipes to allow this to happen, make sure the downpipes aren’t touching the frame especially on the left side, one pipe goes behind the side stand bracket and one in front. Once everything lines up, nip up the lower manifold clamp to fix it in place, loosen off the upper pipe until you can fit the rubber balance pipe, realign the upper and tighten the footrest bolts first, then the manifold ones. If you’ve got it right everything should look aligned from the rear with no twisting in sight."

That's how also I see it. Could it be that the two nuts that fasten the brackets to the silencers are to be tightened the very last? Looking at the pics of these brackets, you will notice that the two holes for this, are designed thus, that they can slide a little bit, possibly to avoid stress. I have overlooked the design of these holes in the past. What do you think?
-
Yup, that way you can make sure the little balance pipe fits.
Be prepared to "modify" slightly the bends on the aftermarket brackets to get everything correct

When you prefer to do it like this ^, it implies you bring in the 10X35 hanger bolt from in to out, meaning the nut will be on the outside of the footpeg. Probably doable, be it that it deviates from what pics in the parts lists suggest.
Furthermore I miss in Ken's description an explicitly mentioning that, in the process of mounting the exhausts, brackets should not be fully tightened to the mufflers, not until the very last. IMO it wouldn't hurt to lube all parts that will need to slide somewhat into position with some vaseline or silicone grease.
I haven't given up hope that we in a joint effort can establish the correct working order in a set of numbered steps for once and for all. Think instructions Honda labourers at the assembly line must have had. Does the Delkevich set come with instructions? Probably not. ;D
I must say I became quite frustrated when I had to repair half of the 8 threads in the head where the studs sit. They're easily damaged when stressed. Not that long ago someone suggested to tighten them the last. In my - as always - humble opinion that would cause such a stress.
-
As you have hinted no instructions with my Delkevic system.
-
Fitted mine and they sound excellent. I used fitting method on this site for fitting stock exhaust.
I am very pleased with them. Had a quick run on bike and all seems good performance wise.

Fitting stock 4x4 exhausts is title of post. Originating january 2011.
Good luck guys

Recieved my exhausts yesterday and very pleased, well packed and next day delivery for £950. A very comprehensive kit including all brackets and clamps plus exhaust to head clamps and gaskets. Even noticed the rubber stop for the centre stand. Will fit them once I get Lazarus properly sorted, living in my bedroom til then!

Now £1099.99 but still £50 off if quick. Those who bought early did well.

Busso seem to have reacted to the new reality. £786 + unfortunate UK import at present if you can get them.

Hi buddy. It was originaly posted by "SohRon" in jannuary 2011 on this ste.
I found it through mr google. I put fitting cb500 four exhaust into my google search bar and it came up.
If SohRon is still on forum try looking him up. Its a very comprehensive guide with pictures at every step.
Hop this helps you out.
Ps. Taking mine foe a run on easter sunday for the day. First proper run this year. Looking forward to it.

Sohron has learned me that the bracket of the lower pipe is supposed to be at the inside of the frame eye and the bracket of the upper pipe at the outside. So, unhappy with both brackets on the outside of the frame eye, I have yesterday (re)fitted both exhausts left hand side, with the help of a friend. Thanks to Ashimoto I know how to check the brackets. The RH side was allright. BTW, I've noticed that most CB500/550s out there, have it wrong.
Sohron's description is very useful, but because he does not mention fastening the brackets to the mufflers, I have made an attempt for a full step by step guide, which can be used for new and used exhausts alike.
I recommend to consult Sohron's pictures in the process. They are brilliant.
Please comment and feel free to correct my English.
Assuming you have all parts on the floor next to the bike, this is how I would do it. In the following I'll concentrate on the left hand side.
1. Apply some copaslip on the threads of the 6mm studs (head) and test the nuts will turn smoothly.
2. Dito for the 8 mm studs at the mufflers and the 10 mm hanger bolt and their nuts.
3. Check the brackets are in good order and not bent (you may consult pics below, courtesy Ashimoto).
4. Smear some vaseline or silicone grease where the brackets will contact the mufflers.
5. Dito for the balancetube that is to be between the mufflers at the rear end.
6. Position the brackets onto the mufflers. Note how Honda designed the holes, so make sure brackets can still slide somewhat!
7. Have the footpeg* with its 10mm bolt and its (spring)washer** at hand.
8. Check you have removed the old gaskets from the head and insert new ones. A dot of vaseline will help them stick in place.
9. Semi hang in the upper exhaust in front, just like Sohron shows. With one hand slide the JOINT over the studs making sure the two collars – their flanges facing the JOINT - stay in the correct position. Leave it there for the moment and let the rear end of the muffler rest on a high enough pillow or mattress. This helps a lot. No matter how concentrated you are, there is a risk a pipe will drop. No problem for a new one. Dropping a used pipe however can loosen the inner rusted damper.
10. Semiposition the footpeg*, its 10 mm (spring)washer** and bolt.
11. Now, with one hand covering the front JOINT, so everything there will stay in place, raise the muffler's end and use thumb to push the 10mm hanger bolt into the frame eye, so it now protrudes the latter by 1 or 2 mm. Leave it dangling there for the moment.
12. Position the connecting balancetube loosely over the little pipe of the lower exhaust.
13. Now repeat step 9 for the lower exhaust. On the LH side this pipe will route behind the side stand.
14. Raise its muffler end and position he top of its bracket on the inside of the frame eye, while allowing the balancetube to fit the alining short vertical pipes.
15. Push the 10mm hanger bolt fully in and fit loosely the (spring)washer** and nut.
16. At front equally fasten the 6mm nuts till some resistance is felt. Then semifasten the hanger bolt. Semifasten bracket nuts.
17. Before fastening further, check everything is in the right position. Check all bolts of the oilpan are accessible from below.
18. Fasten the 6mm nuts in front a bit more, then the big hanger bolt a bit more, then the 8mm bracket nuts a bit more. Now it is time for a final check to see everything is in the right position. The balance tubes and oilpan bolts are indicators.
19. Tighten the 6mm nuts in front. Gently! Do NOT use a torque wrench! Then tighten the big 10mm hanger bolt. Tighten the 4 bracket nuts. Finally for the 10mm hanger bolt, you may use a torque wrench.
20. Fasten crosshead of the balance tube
(Sigh!) If only Honda had made the exhausts in two parts to be connected with a joint halfway. So headers and pipes in one and the wider mufflers as separate parts.
* Later models, like the K2 had angled footpegs.
** The various CB500/550 parts lists show the plain washer and the spring washer in different positions. I don't think it matters much where you fit them.
