which should i get? an h-pipe or x-pipe? depending on which one, what brand should i get?

 

Don't waste your money in my opinion unless you can get your muff guy to do it for free. They don't add power, and if you get a true dual, which would be the only reason to get an H or an X pipe, you change the sound. Personally I think the H pipe makes it quieter. I love the stereo sound of a full seperate true dual exhaust personally. But it's a personal preference.
