With a name like Monster you might think the Banks Monster Sport exhaust system obnoxiously over-powers in-cab conversations and music — not so. Unlike the noisy drone of many straight-through mufflers, this Monster’s muffler is extensively sound-tested and engineered with a unique expansion chamber and spun ceramic, a very high-temperature packing. The result? A rich, authoritative exhaust note that isn’t domineering — yet massively improves flow over the stock muffler! Now that’s a Monster!

Finish off this expertly engineered Monster with the optional Banks 5" rolled-edged tailpipe of polished-stainless steel. It’s double-walled design features a 1/2" air gap — preventing heat from tarnishing its mirror finish. This Monster’s crown adjusts with a clamp, letting you decide its position on the tailpipe. All considered, the 4" Banks’ Monster Sport is one cool cat-back exhaust system.
