APS TP's and APS exhaust
 

Has this been dyno'd on a stock Z??? I am wondering if the gains are similiar to every other combo out there. What do you guys think? I am very interested in buying it.

Do the APS test pipes have resonators? Also, where can you buy them?

i dont think there resonated....aps dealer

I believe they are just strait pipes but I will check in with APS to verify.

Also, as far as I know no one has them installed on their car in the US
