test pipe?
 

what's the best test pipe for my nissan 370z nismo 2011? I am planning to keep my stock nismo exhaust, should I go for resonated test pipe OR "non-resonated?" Which one will make my Z sound more aggressive?

Give tony @ fast intentions a call. I may be a little biased though :)

Also try Berk Test Pipes.

I like the motordyne art pipes, I'm switching the cat back to fast intentions from MXP but keepin the art pipes cuz they're great
