    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. 05 G35 Coupe review by Kerry on 3/2/2016

      After reading the reviews, this was a no brainer. I still had the original exhaust on my G and i started having issues with rusting through. Shipping and packing of this was extra-ordinary. Even the Fedex driver was complimenting how great this exhaust was shipped compared to others. I've only had this on my car for 2 days now. I also got the hi-flow cats to go with it. I surely feel a nice increase just in throttle response with adding of these two items. Hands down an awesome buy and certainly would recommend this to the next person wanting to buy it. GET IT!

    2. Andy Rovito review by Andy Rovito on 12/31/1969

      This was installed on my '06 G35 when I bought it used nearly two years ago. The system is really awesome. As far as HP and torque gains I cannot speak for it because I do not have a base comparison. However, the sound it makes is intoxicating. I do not get tired of the sound ever, at cruising speeds it is very mild and does not drone, even when at higher cruising speeds and the engine is winding above 3K. Accelerating and on throttle sound is great and I get compliments all the time, no complaints either. The whole system is holding up to corrosion very well, and I live in an area where the roads get heavily salted in the winter. Can't wait to save up some extra cash and get the Stillen cats too just to open it up more.

    3. Matthew Jenkins review by Matthew Jenkins on 12/31/1969

      The Stillen cat-back exhaust system arrived in two large FedEx boxes right on time. My master mechanic offered me an OEM exhaust system installed for one third the cost of this system. I opted for Stillen because durability and performance. I have been working with my master mechanic for years and this was the first time that he has ever commented on anty parts that I've supplied. He said; "man, that exhaust system is beautiful - a work of art"! Like I said, I didn't want to have to ever replace the exhaust system again, and I won't with this solid stainless steel. Performance? Well, I don't know about the number but, my G-35 shits and gets - much more than ever before. This Stillen exhaust system? You will not be disappointed with the quality, delivery or performance. I'm an old guy - I know what I'm talking about. Awesome! Buy it !!!
