Scotto, it's too bad that reducer isn't an inch longer, so I could run a short pipe and a lawnmower muffler.
This Dominator pipe is LOUD! even with the hose and muffler. The exhaust pointed directly at my butt and the mounting bracket needed repositioning on my friction drive. My friend Rick runs a Dom pipe on his 460/Staton/NV build. This pipe will NOT clear the Staton gearbox unless you cut and reposition the pipe. Rick cut and rewelded his pipe. It works VERY well for him now.
I have a spare Dom pipe, so I might cut/weld it to fit one of my projects. In the meantime, I'll run my SBP expansion pipe on my 460. It is EXTREMELY quiet, more quiet than the stock muffler. The SBP might not be as powerful as the DOM, but it is so docile, especially in bumper-to-bumper traffic.
My 460 engine might be producing about 5 hp.
My friend Rick and I break clutch springs on a regular basis. It's probably due to the bumper-to-bumper traffic we ride in, and maybe the fact that we never pedal our bikes from a standing start.
