I hope to have a ride coming up in our open desert area that would hopefully be able to give us some info. But again what should one expect to gain with a header and jet kit? Does a couple hourses matter from 44hp to 46hp?
I think I might have done better this time at Pismo's comp hill (muffler only, stock jets, lid on, K/n, edge paddles) but it was my first sand experience. Then I switched to the stainless headers and jet kit 146/148 and won more often or tied the faster ones but had alot more experience dragging in the sand. A light tree would be great since everyone just starts to race when they want to.
I like the carbon fibre muffler, it looks cool.

 

Newrap you said that yours stuck out past the stock grab bar? Was this the aluminum slip-on cause my carbon fits within stock grab bars limits so wheelies are ok. And yes the allens will vibrate loose or come out like mine did on a long weekend. You can use the allens from your stock pipe if you lose one. I used Blue Loctite on all.

 

Uh one last thing....I "blew off" the slip-on, after the newest mods I did for the Pismo drags, from the header so make sure you properly install and tighten the heck out the that nut @ the slip-on to the header.

 

It stuck out just a tad more, but when I had my wheelie accident I broke my grab bar. I thought I had my slip-on tight enough on the stock pipe till I noticed all the plastic above the connection was black. Had to tighten the heck out of it. All in all though, I'm incredibly happy with my Raptor. I thought the slip-on, Uni filter assembly, and Dynojet jet kit really woke the thing up. The bottom end is a little better than stock but the gain in the mid and top end was great. Throttle response was greatly improved also.
