Adam N. ★★★★★

I was worried about getting a CEL after replacing my old cat, but this unit fit perfectly and the O2 sensor bungs were in the exact right spots—no check engine light at all. The stainless steel shell feels solid, and it bolted right up in about an hour.

Amelia V. ★★★★★

Finally got around to installing this on my 2017 STI and the check engine light has stayed off for over a week now. The corrosion-resistant stainless steel construction gives me peace of mind through salty winters.

Emma ★★★★★

Finally, no more dreaded check engine light—the mandrel-bent tubing made installation a breeze and it’s been running perfectly since day one.
