Delkevic Exhaust pipe

Hi,

Looking at the Delkevic four into one stainless steel exhaust pipe. There are some springs between the downpipes and the silencer which I am wondering what they are for and whether they could be removed?

thanks,

McCabe-Thiele (Ted):
I suspect they hold the silencer in place & allow for expansion - plus they might be related to noise resonance?

K2-K6:
Fairly common with rigidly mounted exhaust system (both car and bike) to have the header pipes entering with a "slip" joint to avoid cracking, while being retained by a spring, or pair per pipe. Should only work with them fitted.

Just a type of design, often seen on race pipes.

Oddjob:
Same system holding my Akrapovic together on my 1300, much prefer it to the welded type TBH, it comes part easily and makes for really easy cleaning. Plus if you ever want to get another surface finish on it it makes that easier and cheaper to do as well.

One thing I would advise though, buy a spring puller, makes the job much easier.

Cynical me says that this is just “marketing”.

OK for MotoGP and therefore a “must have” for any self-respecting modern biker.

My Tiger 660 doesn’t have one. Should I be upset?
