370Z Exhaust System

Why do so many 370Z owners choose the STILLEN cat-back performance exhaust system? They know STILLEN exhausts deliver more power, sweeter sound and higher quality than other brands.


Dyno-proven 18 horsepower net gain at the wheels

Consistently wins magazine shootouts for biggest power gains


A refined and melodic engine note both inside and outside the cabin

A touch of added aggression without headache-inducing drone or whine


Polished stainless steel construction Finished with 4-1/2 inch polished 304 stainless tips

Made in USA with pride by STILLEN craftsmen

STILLEN is proud to offer a complete cat-back dual exhaust system for the Nissan 370Z. Each STILLEN aftermarket performance exhaust system is expertly constructed by STILLEN craftsmen. These artisans bend, form and weld top quality 304 stainless steel tubing, mufflers and exhaust tips. Then they carefully polish each component to a high finish for durability and good looks.

You can be confident your STILLEN performance exhaust system will withstand harsh weather and road conditions for years to come. And for added reassurance, STILLEN offers a limited lifetime warranty against rust-through and manufacturer defects.

Count on the STILLEN R & D team to extract every ounce of hidden horsepower from the VQ37 powerplant. We’ve spent nearly 30 years designing and building proven Nissan performance parts. No wonder our performance exhausts systems consistently dominate magazine shootouts for max power output.

You’ll enjoy the fruits of our labor, thanks to an 18 horsepower net gain at the wheels. That’s additional power you’ll feel from the driver’s seat.

And you’ll hear the added power too, thanks to that signature STILLEN sound. The 370Z Cat back exhaust system adds a refined, aggressive edge to the engine note, especially under power. Our customers describe the sound as ‘mature’ and ‘melodic’. And there’s no headache inducing drone or whine to spoil the party, even on extended road trips.

More power, sweeter sound, higher quality. That’s aftermarket performance exhausts systems done the STILLEN way!

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.

    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.

    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.

    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.
