Great system. Had it welded on for max performance would suggest to do this as well. You don't have to though

Really happy with the CORSA. I have a 6.2L and this exhaust really wakes up the sound of the motor. The factory exhaust was asthmatic and made the engine sound small and pathetic. The CORSA gives it the baritone the V8 deserves. Other people complain about drone but I had disabled V4 through Diablo Sport inTune so I did not have drone. The only complaint I would have is the price but I am happy overall.
