127125, gst cat back
Posted by jaimer, Aug-08-09 02:31 PM
I have a question and ive been searching but dont know the answer.

On the power pages it stated you can install a GST cat back.

On my car all i have installed is the GST muffler tip.

I read the pipping of a GST is the same size right??
and the only real difference is a extra resonator and muffler tip.

I always thought their pipping was bigger then a none turbo model.
I was going to install the their pipping but if its the same size i should just leave it alone right??

The only difference it would just be more quiet right>?

Yes the piping diameter is the same, both 2" I believe. This thread had some discussion on it:
