i'm going to put headers on my car( and which ones if any keep there nice look and make horsiestoo) and right now i have like 2 1/2 inch striaght pipe back to a 4' carbon fiber muffler with the silicner out would a cat make any more power after i put the headers on?

 

Direct experience, no. BUT my pal Bart, has one installed on his Integra. Hes got a Greddy TT exhaust, and I heard the car before the cat, and it was wicked loud, and after the cat was installed, which made it a lot more quiet. He said it added a couple horses. I also called him tonight, and he said that it was a really easy swap to do yourself, but you just have to watch out for O2 sensors.

 

NeonKiller, the typical consensus here is DC sports headers are the best bang for your buck. The car will make more horsepower with them, and it will also help your car breathe better.
