question about cat vs. straight pipe and possible damage
I mentioned to a co-worker today that I was thinking of fabing a modular piece of straight pipe to swap with my cat at the track. He told me that I would burn my valves by not having proper backpressure. I just wanted to hear what some of you guys have to say about that. I know some of the guys in Canada run without one all the time, have any issues? I think he'* nuts but I'm really interested in what you guys have to say.
EDIT: maybe I should have put this in P&B
Gutted air box, K&N drop in, MAF screen put back in , NGK tr-55 @ .55, 180* drilled t-stat, INTENSE 3.4mps, Aeroforce, High-flow cat, and one BIG F-ing smile.
