I have no doubt it will sound great, but the fact that it is not a true bolt on system that requires cutting the OEM exhaust might be a deal breaker for many. My Eisenman sport system included a connecting pipe that would bolt right up to the stock mid pipe. When I decided to go back to the OEM exhaust, the swap was a breeze.
