We Manufacture.
We Don't Just Distribute.
Most exhaust parts suppliers are distributors.
They buy from a manufacturer, mark it up, and ship it out. When they're out of stock or your application is unusual, they're out of options.
Auto-Jet is the manufacturer. We make the parts.
That means we carry the inventory, we control the quality, and when a standard catalog part doesn't cover your application, we can fabricate one that does.
We bend tube from 1" to 6" diameter and can work up to 10" material.
Our fabrication department builds complete assemblies — the part fits right because we made it right. And if it's in our catalog, it's available for shipment.
You can't sell from empty shelves.
Built to Fit. Built to Last.
Every part Auto-Jet makes is produced to OE standards or better. Our quality policy: check the first one, the tenth one, and the last one on every production batch.
