I'm about two months out on production, pricing will be announced at that time.
The header and the muffler are two seperate piece's, if you wanted just the header that would be no problem but keep in mind that all the after market "slip on" systems are made to suit the very small (1¾" O.D.) tail pipe of the stock header, my header has a 2¼" O.D. tail pipe.
When I first built the 2.3 System, I built it with a 2" O.D. tail pipe, this soon proved to be insufficient so I stepped it up to the 2¼" pipe, the power increase was significant.
So if you want to stay with your small after market muffler, you will not get the power gains available.
None of my systems are "Harley obnoxious"
As Tal has aid, following Mulks on his GT was not at all a problem noise wise, until he gave it full throttle and dissapered.
