Your not contradicting me, we are on the same page. LOLbig_mike said:not to contradict randy but the purpose of an H pipe or an X pipe in the exhaust is to equalize the flow of exhaust through the entire system. You see, the H and X pipes create a vacuum of sorts to get the exhaust out quicker which enables less backpressure which means more power!
So, talk to your muffler shop and see which one is right for you.
