Thomas Y. ★★★★★

The flange and extension pipe saved me a ton of fab time—bolted right up without extra bending. The high-flow cats definitely woke up the exhaust note, and the welds look clean and solid for the price.

Andrew X. ★★★★★

Wasn't expecting the flange extension pipe to save me that much time, but having it bundled meant I didn't have to cut and weld anything extra. Bolted the high flow cat straight up and the exhaust note sounds way cleaner now.

John ★★★★★

The flange lined up perfectly with my existing exhaust, no cutting or welding needed. I did have to pick up new gaskets, but the metallic cat itself bolted on in about an hour. Sounds throatier now and no check engine light so far.
