I have been searching , but couldn't find any numbers on this site and off of it. I am going to be purchasing the EVO 2 by mid June and wanted to find out some perfromance numbers before i forked out the cash.

For anybody intrested in purchasing the EVO 2. RACING ZONE AUTO HOUSE, here in Orlando and Tampa are selling EVO 2 cat back systems for $475! Thats a steal! From Greddy direct, they are selling them for $699. Big diffrence if intrested here are there number. Tell them Raphael sent you , speak to Tommy or Brian,number is 407-273-0099.

Cool Japanese guys that now there shiot!!!!

 

My guess is you will not gain much, if combined with intake you will see a slight increase in hp numbers.

 

Maybe 5HP at most. Cat-back systems produce more sound than power.

 

This is the only dyno I could find with the Greddy Evo. The dyno also includes a high flow cat. Org member bgates also dyno'd a OBX catback on a VQ35 and got 5-7 hp throughout most of the rpm range.

I was just reading through the link I posted and noticed the in one post dated 2/25/02 word was that Stillen will be coming out with headers soon. LOL

 

Thanks guys for finding that info, the way i look at it , 5-7 hp isn't much but when combined with other performance parts ,in the end everybit helps in the end. Already have a Injen Intake and i am loving it, can't wait to get the EVO 2!!!

 

With my auto, it would fight for traction in first gear from 5000 rpm to redline. After removing the Evo and going back to stock, there isn't even a chirp.

 

If you don't mind me asking, why did you go back to stock? So the Evo did benifit in some gains then for you?

 

Yes it did!

Went back to stock because i plan on selling the car before long.
