Christopher ★★★★★

Was looking for a weight-savings upgrade without losing that deep rumble, and this 5x5x14 muffler delivers exactly that—the dyno-proven numbers convinced me. Bolted up cleanly under the car, and the straight-through design really opens up the exhaust note on acceleration. Exactly the sound I was aft

Lily J. ★★★★★

Bolt-on install was straightforward, and the weight savings over my old muffler are immediately noticeable. Cruising at highway speeds has a nice rumble without being obnoxious inside the cabin.

Ryan ★★★★★

That deep, throaty tone at startup is exactly what I was hoping for, and the straight-through design really woke up the mid-range on my truck. I’m glad I went with the 14-inch length—it’s not too loud inside the cab but definitely turns heads outside.
