I am replacing my strait pipes with mufflers. I looked at 3 inch diameter and 42 inch long primex mufflers was wondering if they are quiet running? I can build the excact same with the stailess steel pipe. Also I was wondering if an H pipe between the two exhaust pipes would quiet the sound and help performance. I have seen this on other boats and was just wondering? Any response would be appricated.

I had a supra comp with straight pipes,now with new boat a quiet exhaust.I would like to hear a little more rumble.The comp was a little much at times.I would think the H pipe would help to balence the presure and do nothing to silence them.
