Steven ★★★★★

Swapped out the stock muffler on my F-150 and the difference is night and day. The straight-through design really opens up the exhaust note without being obnoxious on the highway. Fit perfectly with the offset/offset configuration.

Hannah M. ★★★★★

Installed this on my '68 Mustang and the offset/offset design made routing the exhaust simple. The straight-through core really opened up the sound—deep and aggressive without being obnoxious. Definitely woke up the old V8's performance.

Ryan G. ★★★★★

I’ve got a ’70s muscle car project, and this muffler’s straight-through design gave it that deep, rumbling tone I was after. The oval shape fit nicely into the stock tunnel without any clearance issues. Definitely woke up the exhaust note without being obnoxious on the highway.
