did anyone feel a big diffrence in power after installing the catback? what are the hp gains supposed to be from installing this catback? how does it compare to flowmaster?

 

Alright as far as power goes you can tell a difference i think it'll be better once i get my cai. Second flowmaster sux i heard a z28 with flowmaster on it and it doesnt even compare to my hooker hooker is really a good catback for the lt1 in my opinion

 

I have an intake and hooker catback, and the difference is definately noticeable. You may (read: will) lose the burst of power you get way down low in the rpm range, but due to traction issues, it doesn't really matter anyway. it pushes the torque up higher in the rpm range, and makes the car pull much longer. as long as you keep the revs up you'll feel a nice increase in power. That downshift to 2nd gear becomes pretty wild
