Do YOU run an O/R H Pipe? - Step Inside

[BABstangV6]

Anyone know which sounds better with the stock cat-back? The Mac o/r H or the Mac o/r X pipe?

im going with the mac off-road h too, i was going to get the prochamber, but i like the off-road sound better

Nice. Whats the difference between the H and prochamber? Does anyone know if MAC makes a H-pipe for LTs?

Check the sig man, I also have some clips on my site. The prochamber has a small chamber which gives it the x pipe kind of design, but the h pipe sound. So in other words the prochamber might give you slightly better gains but the h pipe will be louder and deeper.

I am going to be buying some mid-pipes soon. I can't decide if I want an H or and X pipe. I think I'm either gonna get the Bassani o/r X or MAC o/r H. I really like the sound of H pipes but want the bigger gains that the X pipe has to offer. Any suggestions here?

Look at my sig. I love my set up. Off road h pipe by mac with original 40 series flowmasters. It sounds great. Nice deep and loud.

I had both the o/r H and the Prochamber. The Prochamber IMHO sounds better than the H. It's not as loud but it makes the sound deeper. I'm VERY happy with the Prochamber.

I'm pretty happy with my MAC off road h pipe and 40 series flowmasters. As some of you know the casinos here in vegas have garage parking, let me tell you...i can set off some car alarms with my car
