what is the difference between these two exhaust systems other then the 2.5' and 3'????????

JAS

 

3" will make you lose power unless you have FI .... i have the RSR and love it.

 

got any hard data to back up the claim that 3" will lose power?

i have heard from many motor heads that you will loose back pressure and lose hp if you are running a bigger piping with a FI if i am wrong please let me know .. i am going by what others have told me

 

So where can I get the Pro-1 exhaust system? I can't seem to find them on the web.

 

I sold & installed a Pro-1 exhaust on a local 350Z owners car. He showed about a 10hp gain on the dyno. My butt dyno says my Pro-1 exhaust increased power.

www.topspeedauto.com is the Pro-1 website. I'm an authorized dealer too =)

I remember that vid clip of the 350Z that was posted. It sounds absolutely outrageous... ...in a good way. Very sport-bike like... ...maybe half of a Formula 1 car engine. lol. Sounded like titanium as well. The sport-bike sound really hooked me.

Moog, it's just stainless, isn't it? Any idea on what the weight savings/gains are for the G coupe?

Care to share a price range with us on the system?
