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?
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
