Seems the "quiet" pipes don't deliver much in the way of "more power". I seen that the eco series pipes from HMF are fairly quiet? But don't really give it much power over stock, but it does sound a bit better.

The Utility Series pipe I just put on is amazingly loud, it is truely obnoxious but it comes with siginifigant power gains too. I am impressed with the quality of the pipe as far as workmanship goes it's the best Ive seen in pipe makers.


I am thinking about rigging up some sorta stealth slip on secondary muffler I can hook up on the end of my HMF pipe for when I need to make things less obnoxious
