Infiniti G37 Exhaust

STILLEN has developed a new Infiniti G37 Cat-Back Exhaust System.

STILLEN's Cat-Back Exhaust System helps drum up substantial horsepower and torque, giving your G37 the extra edge of performance. This Cat-Back Exhaust System is a true Cat-Back System, and is crafted of Mandrel-bent Stainless Steel for a long service life. At idle the STILLEN Exhaust is unobtrusive, and at higher speeds or under throttle, STILLEN's recognizable, performance sound is evident. This is a pleasing tone, authoritative and yet responsible. Not only does this exhaust system have a sharp, show ready look, but it also offers impressive horsepower and torque gains as well as a lifetime warranty and is easy to install.

STILLEN's Cat-Back Exhaust for the Infiniti G37 is built for power. Power that you can feel across the power band with a big gain on top. Mileage gains during highway travel can be expected as you cruise at steady speeds. The free flowing performance mufflers and tips are made out of polished stainless steel for long life. The Stillen fit and finish is second to none. The improved airflow created by the addition of the exhaust is verified by the significant dyno HP increase.



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.


G37 Dual Exhaust System

  • Nice!

    I received the kit in two large boxes, very well packed and protected for shipping. My son and I installed the kit in my garage with very few tools required, a floor jack and one pair of jack stands. Install was only about 1½ hours start to finish and that was working at a comfortable pace… no rush. The instructions were great, the kit is very well made with quality material and fit like a glove, no modifications at all… Stillen really did a nice job on this kit.
    I was concerned it would be too loud for my taste as it was going on a nice car and did not want to cheapen it (2013 G37S) It has a nice note at idle, cruising but not annoying (almost stock) and sweet aggressive tone at WOT. I paired this kit with the K&N Typhoon intake and can really feel the additional total 33 HP… it was fun to drive before and now WOW! Next is a tuner :)

    I replaced the stock exhaust and intake with the Cat-Back exhaust and Long-tube intake on my wife's 09 G37 and it was a big improvement. Not only does it have a really great sound, it runs great with a very noticeable increase in performance. I'm hooked on Stillen and looking for more toys!

    I replaced the stock exhaust on my 2014 Q 60S with this system and also installed the Gen 3 Long Tube Cold Air intake. Not only does it sound great and perform like a champion I even get improved gas mileage....assuming I keep my foot out of the gas. I couldn't be more pleased. Has that well recognized Stillen sound under throttle but factory quiet at highway speeds.
