Penelope L. ★★★★★

The check engine light finally went off after I swapped in the CARB compliant unit, and the mandrel-bent tubing made the install flow way smoother than wrestling with my old clogged pipe. Two weeks of daily driving and no codes, plus the welds look clean enough that I'm not worried about corrosion d

Eli ★★★★☆

Bolted right up to my F-150 without any modification needed, and the mandrel-bent tubing gives me confidence it'll flow well. The check engine light stayed off after installation, which was my main worry. Only ding is that the price stung a bit more than I hoped.

Hannah ★★★★☆

Fit was spot-on for my Tacoma, no cutting or extra welding needed. The mandrel-bent tubing keeps the flow smooth and I’ve had zero issues with the CARB compliance during smog. Only gripe is the price stings a bit, but it’s worth skipping the hassle.
