The system is designed for an aggressive exterior sound and moderate interior sound. It includes "dummy valve stands" to prevent error codes when replacing factory exhaust valves. The tailpipes have Quad 3.50-inch polished 304 stainless steel tips. It's a bolt-on system that uses factory hanger locations and comes with a Lifetime Limited Warranty.
