--- Quote from: McCabe-Thiele (Ted) on December 22, 2023, 10:09:24 AM ---Just posting here again as in the new year I need to decide on an exhaust system. ATM the options are as follows.
1) Replica original - I have no brackets so this is going to be circa £1350 ish from DS with aftermarket brackets.
2) Marvin system £435 plus brackets?
3) SS Delkevic £350.
Does the Marvin system work on standard jets etc?

If it was me Ted I would dig deep and go for the DS/CMS replicas. The additional cost is just an investment really as having them fitted will add that value onto your bike if you ever decided to sell IMHO
McCabe-Thiele (Ted):
Oddly enough my BiL has just visited - he talked me out of the Marvin option on the basis of it being neither fish nor flesh - in my heart I know the four pipe replica is the route makes sense in terms of parting with it in the future as Ash has said - as DS is UK based probably easier if there are any issues with transit damage.
I'm thinking even the chrome on a replica will outlive me - I should have kept my old system to get the bike up & running - it would be an ordeal to fit the four pipe system then have to take it all off if I sprung an oil leak on the block or head.
Another option might be to go for the Delkevic system to run the bike next summer then fit the 4-4 system next winter if all is well - might be a market for a hardly used Delkevic.
Anyone have a spare Delkevic for a 500 they want to part with?
Sesman:
Hi, Ted. Personal choice as always, but I’d be inclined to go for the 4into 4. My mate had a Marvin way back in the late 70s. It sounded great initially, but after a few 50 mile round trips to college it all became something of an aural assault. He changed back to the 4 into 4 pretty quickly.
As for cost vs value vs aesthetic's, you know the drill…..
Merry Christmas.
McCabe-Thiele (Ted):
Even though you are probably out in the Ocean somewhere Phil I know you are right - it's going to be the 4 into 4.
How much better off I would be had I bought your 500 when the opportunity was there, that said as it's about the build more than the ride in my case. IIRC the new owner of your 500 has since sold it - must be a Teflon bike.

Oddly enough Ted I think removing the original 4 into 4 is easier than doing a 4 into 1, you can do them one at a time, so less weight, you can just remove one if that's all that needed for whatever job you're doing, plus removing a single pipe means less chance of damage to the frame paintwork.
The other advantages are noise, the engine runs better, the final look, the ease of maintenance, some need removing to access the oil filter but they were old systems like the Piper, not sure if that's the case these days and the final advantage is it adds value, it doesn't take it away.
Don't forget the balance tubes at the rear as well as the brackets AND the stand rubber.
If I was giving one piece of advice to anyone fitting an original system it would be to check the side stand, if it's bent (and most are from hitting the road when it's left down) it will clobber the number 1 pipe as it goes up, eventually you'll have a nice little dent there which sort of ruins the look. Plus it scratches the chrome allowing rust etc to start to form. Same for the main stand, some reports of the copy systems not having the bump stop located correctly and this means it doesn't contact the stand correctly, best to check it does and fix the problem if it doesn't. This was on the first run of these pipes so maybe that fault was identified and fixed.
