Exhaust pinging/creaking
 

On my S4r after stopping the exhaust pings/creaks alot when cooling. Never had this on any bikes before.

Is it due to being to rigid? I read some where its a sign of cheap steel being used?

I have an Akrapovic slip on and Dp cat removal pipes:D

one of the best sounds you can get in my opinion..........sounds like its running well!

Its when the engine is turned off I mean:o why does the sound mean its running well?

My 999 does it mate, Its just hot metal cooling down. I like to think its my bike talking to me and thanking me for a nice ride. (I need to get out more):biaggi:

Steel contracts as it cools down, hence the pinging. I love that sound as well.

Cool its an ok sound :lol

Just never had it that loud on any bike before:):)

Stainless 'creaks' a lot more than mild steel so its perfectly normal. My car started doing the same thing when I fitted a stainless system.

I love that sound it always happens after a good ride!

Its a good thing honest. Mean your riding it more than cleaning it. (Love that sound too)

Quite normal, particularly if you've been feeding it plenty of gas :-)))
