I purchased the aFe exhaust after reading a test article that documented HP and torque gains. Installed the system on GMC 3500 with Duramax. Very impressed with the quality and completeness of the kit. Installation was easy, even after losing the directions and fit is perfect. In fact, it took twice as long to get original system off. Sound quality is good - aggressive, but not annoying or droning. I could not be more pleased with the system, especially at the AutoAnything sale price.
