I am going to be ordering the top speed pro1 exhuast in about a month or so to go with my ims resonated pipes, and my jwt popcharger. What kind of gains can i expect from the catback from pro1.

 

I'd venture to say a conservative 5-6 whp gain. Bolt ons for our Zs don't really add that much power. You'll probably get more with their Y-pipe or another aftermarket Y-pipe though.

 

Well im goin to get the y pipe from them, as well as the headers after the catback. IM just tired of the stock catback. THere are alot of 350z's around here as well as g35s. Around town i wanna be distinguished and stand out above the rest. Plus i dont think its that great to add headers, and a y pipe to the stock exhaust. Im goin to bein staying NA becasue i dont plan on spending 10gs on my car i know im not goin to keep it more than two or three years i dont see y i should spend 10 grand on it. If i wanna go really fast ill just borrow my bros supra.

 

ive heard 10whp somewhere...but that was with the y-pipe i believe

 

you're definately going to lose some low end torque if you stick with stock headers. honestly, i never really noticed any upper rpm gains from my pro-1. i was probably too busy listening to the exhaust. but nice choice on the headers. they will provide a decent hp and torque gain for a decent price.

 

Most of the gain will come from the resonated test pipes, not the exhaust.
Remember to reset your ecu, the difference will be very noticible.
