Hey Im buying some used mac long tube header and i have a bbk x pipe right now and i dont think theyll fit together. So i was wondering what is a better bet to go with a H pipe or and x. Also dont really no what the difference is besides the shape.

thnaks,

THe h pipe gives a deeper more muscle car sound, the x-pipe is more of a high pitched exotic sound. The h gives you more torque down low, and the x gives you a couple more ponies up top. The performance gains between the two are minimal, so pick the one you think sounds the best. What kind of catback do you have?

I have spinteck dual side exhaust after my xpipe

I've never heard that exhaust in person so I don't know which mid-pipe would be best, but I would most likely do an o/r h pipe.

Well if you are happy with the sound you have now, you can just stick with an X. If you want to go for a deeper (less raspy) then go for an H.

You may also want to consider the prochamber. It's a nice peice. Kind of smooths things out and gives off a deep tone. A little more pricey though.

The basic rule of thumb is usually: X pipe for straight through, H for chambered and the prochamber for either.

Looks like the spintechs use baffles to make a swirling effect. But don't appear to be chambered.
