    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.

    2. true dual review by Jason on 1/20/2016

      I love how it takes the 350Z stock exhaust note and makes it more aggressive. Easy install, sufficient power, perfect sound.

    3. Eric Mason review by Eric Mason on 8/11/2014

      Th Stillen Cat-back Exhaust my 350Z is truly primal. Thank you Kenny Duong for the recommendation of what intake and exhaust to get. I haven't dyno the Z with new setup but will next month. Paired with the Gen 3 CAI my Butt-dyno tells me at least 25-30hp for the pair.

    4. Patrick Ley review by Patrick Ley on 12/31/1969

      This exhaust fits like a glove. Easy to install and the sound is perfect.
