I think I've patched and riveted my 8 year old 2 Brothers Racing slip on exhaust for the last time. Has anybody out there had experience with the Leo Vince Oval slip on exhausts from Italy? At $265.00 they represent a good value when compared to the competition....but only if they work as well. I will probably buy another 2 Brothers system but before I spend the extra $200.00 I thought I would ask about the alternatives.
