I just installed mine, exactly as they say in the instructions. The front header is literally 1/8" from the left side cover. I'd be shocked if it doesn't melt the finish. I called their tech support dept, and they say that's the way it's supposed to fit.

They sent me an email for how to remove the side cover without having to drop the pipes... that looks like fun.......NOT!!!!!!

 

My V&H Big shots were like that too. I couldn't get the cover off without nearly removing the left exhaust. No damage though.

 

I'd be interested in knowing how you like the Bub 7 Stealths. I had a set of Bub 7s and they didn't work out for me. I need something with a lower sound level.

 

These might be the ones for you. Lower and throatier pitch than stock, and a bit louder... but definitely not what I'd call loud. Probably the best compromise I've heaerd.
