I orignally put the LSR Blackhole on my bike with the Jims 120 Engine great looking and well built pipe, however, I had Matt Gross (Phoenix) attempt to tune the bike with them on, and for the life us we could not get the engine to run like we thought it should.
What we found was that torque and horsepower dropped like a brick. He covered half of the rear of the pipe with a piece of plywood the HP and TQ shot up were we expected it should be. Removed the piece of plywood and it dropped rapidly again. Put it back on and it was great, removed and dropped back down.
This engine was the Jims 120, it had the SBC Vortec Heads, S&S 675 Gear Drive Cams, Kuraykyn 57mm Throttle Body c/w 6.63 injectors, rest engine stock.
Put the V&H Pro Pipe on and has HP of 131 and TQ of 134 lb. ft., so needless to say, ran with the V&H Pro Pipe, now back back the Freedom Cycles True Duals as I was blowing the packing out of the V&H Pro Pipe and after 600 - 700 mile days the noise was apain in the ears.
I am going to try the new BUB Seven True Duals when I get the new JIMS 120 engine in the bike.

I know beauty is in the eye of the beer holder, but has anyone actually tried the LSR Blackhole 2-1 pipes? From what I have read on their site, and other V-twin forum sites, people seem to really like 'em.
