Customer Reviews (4.8 / 5 · 5 reviews)

Riley Z. ★★★★★

Installed this on my 5.3L and the crossmember-back design made for a straightforward swap. Noticed a solid power increase in the mid-range, and the sound is aggressive without being obnoxious on the highway.

Emily S. ★★★★★

The deep, mellow rumble at idle is exactly what I wanted, and the crossmember-back design made it a clean fit on my 5.3L without any hacking. Throttle response feels noticeably snappier than stock.

Zoe ★★★★★

I’ve had it on my 5.3L for a few weeks now, and the sound is deep without being obnoxious inside the cab. Definitely feels more responsive when I get on the throttle, and the stainless steel construction gives me peace of mind about rust.
