before buying the invidia i liked the look, quality and attention to detail. i didn't think it was going to be as loud. after viewing the exhaust videos i felt the invidia was the best sounding, but again, was surprised at the loudness after installation.
the only saving grace, it's loud only on acceleration. but when you get on it, above 4000rpm, it sounds great. it also sounds great while on the interstate at a steady speed.
