Customer Reviews (4.8 / 5 · 5 reviews)

Carter ★★★★★

Swapped out my stock muffler for this oval multi-chamber and the difference in sound is night and day—deep tone without being obnoxious. The perforated tubing really seems to smooth out the exhaust flow, and installation was straightforward with no fitment issues.

Scarlett ★★★★★

The baffle design really opened up the sound on my truck without adding drone inside the cabin. Bolted right up to the existing pipes with no modifications needed, and the fit is spot on.

James ★★★★★

Dropped this on my '73 C10 and the idle drone I used to have is almost completely gone. The perforated tubing and baffles really do a nice job smoothing out the exhaust note without killing flow.
