i think fit on my BBK was okay. I really have no issues. But i have seen Bassani Mid-length at the Carlisle, and i've also seen SLP LT, Both of them are far better quality then that of BBK. I think with Bassani, u might be able to get it on without jacking motor up like that of BBK, as each pipe is separate. and I've heard that with SLP, its easier if u cut mid-section(about1/2" or so) of frange out. But who knows?
Only issue i'm having with mine is that i reused OEM gasket, and its leaking!!!!!!!!
