So I tried to search for a thread like this and couldn't find it, if there is one please link me. That being said I recently put my 2005 G35 on a Dyno. It is the Rev-up in a 6 speed, it has an air intake, a 5/16 inch plenum spacer and a muffler delete. I put 251 to the wheels. What is a good number to expect from it and what has your car put out?

 

That sounds about right. Ive heard of revups making around 245ish whp on avg, but due to the fact that every dyno is different, you sound right about on track, muffler delete is probably costing you some hp though

 

Long story short we discovered the muffler was already cut after I purchased it so its alright for now. A new exhaust in line soon.

 

what brand are you looking into ?

 

Momentum Performance, ARK and Tanabe

 

Just curious but why isn't the Motordyne on your list? The TDX 2 is my favorite coupe exhaust out there and my favorite sedan exhaust is the VQ which I have.

 

I agree, you should consider it, probably the most agreed on exhaust out there I terms of tone/quality. But if gains are what you are after, I believe there's a single exit exhaust that has better average gains, can't remember the name right this moment but it was discussed on the z forums
