Hi, I have a built b20 (eagle rods, ARP studs, JE pistons, 12:1 compression ratio) with a stock b18 head with T1R headers on a 97 civic LX 4dr. I still have the stock exaust (excluding the header and test pipe) on my car.. I want to purchase a new exaust system for my car. I am not worried about sound or anything in terms with that. I just want the best performance for my car. Does anyone have an ideas with what i should go with?
