on a civic it will hurt performance because it is only a 4 cyl. something to do with the backpressure. It helps cars will bigger motors.

a lot of people tell me that but sometimes i get some people that say it adds performance so im just confused anyone else got suggestions!!!

depends on the piping size. if each pipes are say...1.25" each, then it wouldn't be bad. now if both are 2", say good bye to revband power. the lost of velocity will kill the torque. getting rid of backpressure is a good thing. in the end, you'll put down more weight than a single pipe, but hey, it looks good
