Trying to figure out how to get some VP U4.4 REG without paying a $125 price tag for freight. Just would run it at the track/around town when I really wanted to have fun.

any race track should sell it,but remember that race fuel wont make it any faster & could make it slower
After over a year, about 73,000 setbacks, and parts getting lost/people getting shut down it was fired up with the custom exhaust on last night. Builder said the exhaust has a nice unique deep punchy sound, and each time it fires you can feel it in your bones
Going to do the pump gas tune soon when the humidity drops (86% today, been raining all week). Race gas tune will come after pump gas is dialed in.
If sound is any indication, that should be a runner
Thank you!
I went down to the builders shop yesterday to hear it. He didn't lie, the sound waves felt like they were hitting you in the chest. It is WAY loud even just at idle, I like loud stuff but this thing is ridiculous. Thinking about doing a baffle, similar to the Guppy baffle by JBV racing for the street. We will see how the bike tunes below 2500 rpm.
Also, similar to TXCHOP's experience, the valve train was surprisingly quiet upon cold start. We'll see how it is when we get the break in oil out and get it up to temp.

LOL. I have a V-Rod Thunderheader on mine and its as you described. You blip the throttle with it idling and your ears ring. The high compression makes the mufflers job very difficult. You would have to put a fairly large can on it to quiet it down.

With power, comes loudness, lol.

This muffler doesn't do a lot of muffling lol. Sounds cool though
