Hey I was wondering about what cat i should use when I swap in my h22 in my accord! Should I use a highflow cat or shoud i just put in a straight pipe! Im not worried about being emission's legal so i can run it with or without! I was just worried about the backpressure issues and worried about maybe burning up valves with little back pressure! any help would be great thanks!
 
Use a high-flow cat. I'm running a stock cat right now, and I don't have any problems. A test pipe won't cause any problems with your engine, but it will make your car quite a bit louder, and the exhaust noise a little raspier.
