First, I have a recently purchased WW IX GSR...
I just installed a turbo xs downpipe, race pipe and cat back. I used all the provided metal spacers and I think its still hitting the front cross brace and (hitting, but not quite as bad) the back one as well. I love the exhaust tone/ power/ looks but dammit.. nearly $850 and they couldnt have worked this out.
Also, in your opinions, would this cause a cel??

Thank you everyone.

 

I don't see how the exhaust hitting a chassis brace could cause any problems. I removed one of mine when I installed my AMS TBE but the test pipe will cause a CEL but if you run a spacer for the O2 like I did for my test pipe, it'll eliminate the CEL for the test pipe.

 

The race pipe will cause a CEL unles you have the CEL fix or get a tune that eliminates it..

 

yeah bro. if you have a race pipe (test pipe) it will throw a cel. the tephra mods can help you out with that real easy

 

So has anyone had a noise or vibration issue with the contol arm braces?

 

I'm not sure but that's something I should check. I have a rattle comming from somewhere lol.

 

Mine occurs in specific rpm ranges, usually at the top of gears (2nd and 3rd by majority). Its also noticeable when mivec engages. I thought it was the t-case at first and my f**kin heart sank.. then i realized sometimes when i would coast at high r's in the low gears and then let off the gas it was happening. Phew, at least its not trans/drivetrain related...
