Built, bolted, proven

Real cars. Real dyno sheets. Here's what owners say after the headers go on.

Spools like a different car

Backpressure gone. Boost comes in a full 400rpm sooner and it pulls all the way to redline now. Fitment was dead-on — no massaging, no fighting the O2 bungs.

Welds are art

Dyno sheet doesn't lie. Cleaner welds than anything I've had under a car and the coating still looks new after a season of desert heat.

They actually answer the phone

Called about fitment on a swapped G-wagon and got a real person who knew the platform. Parts shipped next day.
