so i went to the shop since my cars been loud up front by my door. Now its ever worse one week later, bad test pipe, i need a new one cut and welded on. anyway i wanna upgrade to the apr stealth exhaust so should i waste my money fixing the test pipe now or is it part of the exhaust that i would be getting??? hellp me i wanna fix or upgrade now

 

Bad test pipe? The APR exhaust does not include a test pipe. It is a cat/test pipe back, so you'll still have to do something about that test pipe.

 

Ebay test pipe? Most likely has a warped flange that is leaking really bad.
