Customer Reviews (4.6 / 5 · 5 reviews)

Zoe N. ★★★★★

Swapped out the stock muffler on my pickup and the straight-through design really opened up the exhaust note without being obnoxious inside the cab. The oval shape fit perfectly in the stock hanger location, and I noticed a slight but real improvement in throttle response.

Riley ★★★★★

Finally got this installed on my old Mustang and it's definitely louder deeper than the factory muffler was. The straight-through design seems to free up the engine's breathing, you can really feel it pull harder from 3,000 rpm on up.

Daniel ★★★★★

Bolted it on Saturday morning and the straight-through design really wakes up the mid-range, exactly the kind of growl I was after for my truck. Fit the oval 4x9 footprint perfectly under the frame, and even with the drone at highway speed, the extra response makes it worth it.
