I'd like to hear some feedback and possibly some numbers for the gains on CBE systems. I personally had the FI new xpipe system and I could tell the gains where there, never dynoed the car but it was more responsive. With that said, how do the other systems such as ARK, Berkshire new exhaust, and other systems compare?

Your input is appreciated.

 

never noticed a gain when i put mine one.. but once i put the HFC on i could tell right away there was more power

 

suweet! ;-D

 

I actually dynoed my car last weekend. I had one done last year with Injen CAI installed, and last weekend my only difference is my ARK exhaust (and BB grounding kits but i doubt that affects the hp) and i only gained 10 hp from last year.
So i believe my Ark exhaust only gains 10 hp, if that helps.

 

What did your dyno at the wheels??

 

On a 3.5HR, FWIW.
