Yesterday I removed the Vance & Hines slip-on pipe and installed a beautiful new full system from Leo Vince.
The Leo Vince SBK Factory EvoII exhaust is a full stainless and carbon fiber system. It took a little while to install, but it was worth it.
At the dyno we saw 161 hp out of the full system, which is almost 6 up from stock. The Leo Vince SBK Factory EvoII exhaust also dropped 6 pounds and increased midrange torque by a mile.
The best part—the air/fuel ratio is pretty much spot-on and we don't need to use an aftermarket fuel box to sort it all out. Impressive stuff.
It sounds pretty insane and even shoots flames sometimes. Sweet!
Seat of the pants impressions indicated a meatier midrange, but I didn't expect it to be so significant.
I'll get the video of the dyno runs posted soon along with the dyno chart.
In the meantime check out the $1200 exhaust over at www.leovinceusa.com.
