Dude knows his parts.
Leo Vince Exhaust and Electronics.
I like their full ti systems, just shipped one today for an 09 BMW G450X.
He drops something like 6 or 7 pounds and gains 10% HP.
It's an all titanium exhaust system with carbon fiber heat sheild etc.
Of course it has the spark arrester and plug with it.
Really nice quality stuff, the pipe today was made in Italy.
I think all of their exhaust is and am not sure on the electronics.
