This Twisted Steel down-pipe with loop relocation pipe replaces the restrictive factory down-pipe for improved flow, performance and an aggressive tone. In-house dyno testing produced gains of up to +14 horsepower and +24 lb.-ft. of torque. This system also accommodates most long-arm lift kits without interference. 3" into 2" mandrel-bent, 409 stainless steel tubing and high-flow (400 CPSI) cats provide optimum flow while maintaining equal length between the exhaust banks and exhaust system without compromise. This is a direct fit system with no modifications required for a hassle-free install.
