I purchased the exhaust offered by Genius and am really pleased with it. A friend of mine is a stainless steel fabricator and he was impressed with the quality. It installed very easily! The only problem was getting to the bolts of the heat shield and the mounting bolts-not easy to do without proper tools. A bit of sweating, swearing and maybe skinned knuckles.
The sound is a nice "growl," much like many sport cars your hear on the road. There is an increase of sound/noise inside, louder at lower rpm's, but that should be expected whenever changing exhausts on any kind of vehicle that isn't a "stock," system.
