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. 2018 370Z – It’s alive! review by Ray on 12/4/2018

    Installed both intake and exhaust on a Sunday afternoon and am amazed as to the fit and finish of both.
    Air Intake - (Gen 3) Dual Hi Flow Ultra Long Tube [Z34] - Dry Filter
    Nissan 370Z [Z34] Stainless Steel Cat-Back Exhaust Systems - Dual Wall Tips
    Now that the engine can breath, the throttle response and improved horsepower are very apparent.
    Throw out your stereo, the sound of the exhaust is amazing.
    The only downside is the location of the air filters, it will take some work to get them out for cleaning.

  2. The perfect VQ note review by Tyler on 10/27/2016

    I went to Stillen because they know VQ's better than anyone and I'm to spend this much I want the best. I've heard all too many of them with exhausts that sound like garbage, the engine just completely loses its identity. The VQ engine loves fiberglass in the exhaust tract and the system has plenty to keep the tone smooth with no harsh rasp that just smears together at mid range and higher rpms like I've heard on every fart can style cat back. It's got a nice deep tone and at idle it almost sounds stock with a bit more beef. It really lights up between 2500 and 4k I've noticed. Maintaining that beautiful purrrr the VQ is known for and is flawless through the range at WOT. It also has brackets to keep the factory resonance weights on the y pipe. Fitment was great although my 2014 chassis did not come equipped with the left forward muffler hanger for some reason but isn't even an issue. Noticeable low and midrange torque gains. I am certain how ever that it is heavier than the stock system. I look forward to purchasing the Stillen cold air intake to complement Stillens excellent exhaust.

  3. 2010 nissan 370z nismo review by Brandon on 7/17/2016

    I bought this for my Nissan 2010 370 Z Nismo Edition car and I must say I'm very happy with it, love the note and a little extra power. It really does sound good!

  4. Excellent. 5 Star review by Porpoise on 7/3/2016

    Wow. What a fantastic product. The exhaust bolted on with no hassle. Perfect fit and finish. The sound is amazing, there is zero drone at any rpm. It is quiet enough at low rpm to sneak in and out of the neighbourhood, and when you approach 4000 rpm it sounds amazing. Very crisp sound. It is the best aftermarket exhaust I have seen and heard. Great job Stillen. 5 stars.

  5. Sebastian Haque review by Sebastian Haque on 6/2/2014

    Brilliant bit of kit and I really appreciate the way Stillen provide pictorial installation guides and dyno charts for their products. The sound is gorgeous when you've got your foot down and unobtrusive otherwise. Well worth the price, highly recommended.

  6. Marvin Yap review by Marvin Yap on 3/7/2014

    This exhaust and high flow cat are a beast!!! Just got my exhaust and high flow cat today and when to my local shop to install after an hour of install I already felt the additional power on my Z.

    AAnd the customer service is 100% satisfaction, Thanks to Dean for helping me!!!

  7. Brian Nakel review by Brian Nakel on 12/31/1969

    Great service, great quality, and great product. Stillen knows Nissan's and built a great exhaust. Dealer installed a "direct bolt-on" in less than 60 minutes. Looks great, nice boost in power. Overall, very satisfied.

  8. Charles Johnson III review by Charles Johnson III on 12/31/1969

    I purchased and installed this Stillen exhaust after comparing multiple exhaust systems on both YouTube (sound bites), and researching multiple Nissan forums. The sound is not brash at all and produces an exotic sports car note.

    After the installation I went to a gas station to fill up and driving to the pump saw multiple people turn and look for where the non-abrasive sound resignation was coming from (a Beethoven symphony in Baritone). My thought is that this exhaust system should be a standard upgrade part at Nissan dealers for the car (no harm - no foul).

    For those of us whom enjoy driving this system produces no back pressure. I do not know whether I had a 16 or 18 horse power increase, but there is definitely a significant power gain.

    Last but not least, I would like to commend Adam Hume (sales representative) for his patience in working with me and answering all of my detailed questions. Stillen has an excellent built and functioning product which I definitely recommend.
