Stainless split-dual system more than doubles stock flow & cuts backpressure 98% for more power & lower EGTs; rich, throaty sound; huge polished tips; safely clears spare tire

Very fitting.
This is no cheap, ill-fitting aluminized exhaust. It's a heavy-duty stainless Monster Exhaust system with constant diameter 4 inch intermediate pipe and two 3-1/2 inch tailpipes. It fits better than the competition, because Monster Exhaust utilizes the factory hangers and maintains proper clearance to all under-vehicle components. Unlike other split-duals, Monster safely clears the spare tire, shocks and brake lines.

Performance art.
With nearly five decades of engineering airflow improvements, Banks has mastered the art of maximizing flow while minimizing backpressure. The polished straight-through Monster Muffler, mandrel-bent intermediate pipe(s) and tailpipes improve flow up to 150%, virtually eliminate backpressure, lower exhaust gas temps and deliver more power to the ground. And the 6X5 inch polished-stainless angle-cut rolled-edge tips have real show quality--get 'em in high temp black or chrome-over stainless! And to help keep them looking good, there's 1/2 inch air gaps to keep heat from tarnishing the finish. Adjustable clamps let you position them on the tailpipes just right.

Not just flow-tested. Sound-tested!
Many straight-through mufflers deliver an obnoxious drone that overpowers conversations. Banks Monster Muffler is extensively sound-tested and engineered with a unique expansion chamber and high-temperature packing. Instead of a drone, you?re treated to a rich exhaust note that?s authoritative, yet civil. It sounds as great as it looks!

Note: Dual exhaust not available for dualies.
