Very fitting.
This is no cheap, ill-fitting aluminized exhaust. Banks' 4” Monster Exhaust is made of rugged, long-lasting 100% stainless steel. 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 head pipe assembly (non-cat-converter-equipped vehicles only), 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” polished-stainless angle-cut rolled-edge tips have real “show” quality!
Not just flow-tested. Sound-tested!
Many straight-through mufflers deliver an obnoxious drone that overpowers conversations. 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!
