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.
