Flow and Performance:
This Mach Force-XP series exhaust system is constructed of 2-1/2" & 3" mandrel bent, 304 stainless steel tubing for maximum flow, low turbulence, increasing torque, horsepower, and improved throttle response.
4" x 12" Polished Resonated Stainless Steel Exhaust Tip:
This exhaust system is finished off with a 4" x 12" polished resonated stainless steel exhaust tip that gives your 4Runner a clean, stylish, finished look.
22" less restrictive muffler absorbs high pitch tones producing a powerful, aggressive, smooth tone under load. Muffler finish may vary.
High quality band clamps and hardware are used for a complete 360-degree sealing surface.
OE-style bayonet hangers are used to maintain a stable exhaust pipe location during any driving conditions. The bayonet tip holds the hanger bushing in place for a long-lasting, OE-style fit. This makes for an easy installation with no cutting required.
