About STILLEN Parts & Accessories

Steve Millen Sportparts, Inc. and STILLEN humbly started their race to the front of the pack in 1986. Starting with aftermarket mini-truck appearance packages, we quickly found ourselves fulfilling customer's requests to build products for other vehicles such as vans and full-sized trucks.

With that came performance parts, suspension pieces, and upgraded brake products such as big brake systems. Capitalizing on his racing career, and knowing what it took to make sports cars perform like no other, it was only natural for Steve Millen to branch out into the import car scene. Over two decades later, we offer a full array of products encompassing styling, performance, handling, and braking products for just about any car, truck, or SUV.

  1. Happy adeitionrst review by James on 3/20/2016

    My car is a base 2014 Q50 AWD. I added this exhauast along with the Stillen high flow catalytic converter. The tune shop i used was excellent (MacAutosport n Denver). The shop got 40 more horsepower to the wheels! I am not sure what that tranlates at the crank, but there is no getting around noticing the difference. Now you can finally hear the motor and the sound is awesome. The power is finally tapped too - now my car drives like its boosted, it really hooks up... not anything near the same car as stock. I cant wait to drive the new 400hp 3.0 turbo just to compare. This is the first time I've had a car that had all the power I want, and I've had a few, lol! I have been able to relax on the idea of actually supercharging. The Q50/VR37 has awesome potential and Stillen can get you right into it!

    Perfect sound when you want it and quite when you don't. Sound is deep, throaty, and mellow. Love it.
