Thomas ★★★★★

Installed this on my truck last weekend and the dyno-proven performance bump was noticeable immediately. The oval straight-through design fits perfectly under the chassis without any clearance issues.

Eva ★★★★★

The oval shape fit perfectly into my custom exhaust routing, and the straight-through design gave my truck a deep, clean tone that's not obnoxious on the highway.

Chloe ★★★★★

I've been running it for about 500 miles now and the bass note at idle is deeper than my old setup, yet it doesn't drone on the highway. The oval shape tucked under my truck easily, giving me more ground clearance than I expected. Exactly the smooth, throaty sound I was after for daily driving.
