Hi I was wondering if anyone on the forums have installed the top speed non resonated test pipes?
I just put them on and it feels as if I lost power due to less back pressure, I believe your suppose to gain not lose power?

any advice is greatly appreciated

thanks.

 

Well I have the resonated ones and I can defintley tell I gained power on the top end.

 

mods like higher flowing intakes and exhaust usually loses lower end torque while gaining top end power. I personally much rather have the low end for daily driving since i hardly race. I've had cai on my tsx before and would never install on another car again. the low end torque loss is sickening esp on a 4 banger like that. also almost all dyno's of exhaust and i would assume test pipes show loss of power down low

 

wow
