X-pipes are nice I was thinking of going that way they make the same power as a H-pipe but at differnet rpm range. If you are looking to the future and thinking of long tube headers nobody right now is making an X-pipe to fit you would have to get them custom cut. Also alot of people that are making X-pipe dont recomend them with Flowmaster mufflers rather go with thier mufflers that flow with the pipes. If I didnt get the long tube headers I would have gotten an Off-Road X pipe a lot of guys are going with them now.
