Berk test pipes
 

I installed my dual exhaust and test pipes last weekend and it has kind of a tinny sound. How much do the test pipes contribute to the exhaust note/sound?

I listened to several sound bytes and saw several youtube vids of the 370 with the same exhaust (Borla) and none of them had the "tinny" sound that mine produces. Before I bought my Z I looked at one other that had a Berk CBE and either Berk test pipes or hi-flo cats and it didn't sound good at all.

Are the test pipes the culprit?

YES, the TP's are to blame, my thread is about 4 down from yours lol

non resonated TP's give you more rasp, which was an insane rattle in my case paired with Stillen CBE. I took them off yesterday and replaced with ART resonated pipes and problem was isntantly solved. zero rattle zero rasp.

Cool, Thx

The combo is berk high flo and Stillen cbe...

lava are you going to switch to ART pipes also?

I'm going to do something I just don't know what yet
