I recently replaced replaced my cat with the Leo Vince decat. Got bored on one afternoon where it wouldnt get above 35 degrees.
Took the Termis off and put this on.
I cut the outlet of the old cat pipe and gutted it, re welded on the outlet at a different angle pointing a little down.
Its loud, not Harley abnoxious but more of a tuned sound.
Pops a little on decel but not horribly bad.
I put it on cuz I was bored but it might stay for a while.
Ive always thought that a Ducati HAD to have the undertail exhaust, it is the Ducati signature, but with nothing under the tail the bike looks more aggressive, sexier.
Now I need to find a undertail solution, something that will cover everything like the superbikes have.
