On my 2.2L Sedan I noticed yesterday taking a look at the header and the conneciton to the downpipe, the downpipe looks like it's severly cracked on several angles. I can tell that the exhaust is slightly entering the cabin because of this but only at idle. Guys, check your downpipes on the 2.2L to make sure you don't have the same. I only have 10k miles on it.

I will check my SS this weekend to see if it uses the same downpipe and cracking in the same place.

Going to take the dealership soon..

Will snap the best picture I can.

 

if it was cracked you could definitly hear it from inside the car! Does it make a ticking noise that speeds up as the RPM does?

 

interior doesn't sound any louder then usual. I called my dealer and they want me to bring it in. It's popping more then anything, (sounds like cold air getting into the chamber).
