Kevin P. ★★★★★

The sound is deep without being obnoxious, and I noticed a real difference in throttle response after the install. The 6-inch round body fit perfectly in my stock exhaust tunnel.

Victoria B. ★★★★★

Installed this on my truck hoping for a bit more volume, but the tone is actually deeper and smoother than I expected without being obnoxious. The straight-through core gave me a nice bump in throttle response, too.

Isabella ★★★★★

Swapped out my old restrictive muffler for this, and the cabin drone disappeared while still getting that nice deep tone. The straight-through design definitely woke up the mid-range pull on my V8.
