Infiniti FX35 Exhaust / Infiniti FX45 Exhaust Systems

STILLEN's new exhaust for the Infiniti FX35 and FX45 is crafted of Mandrel-bent, polished Stainless Steel. This is a true Cat-Back system designed for a long service life, and helps the FX drum up additional horsepower and torque.

Derived from our best selling G35 and 350Z systems, the Infiniti FX35/FX45 exhaust features a carefully engineered double Y design pipe, dual resonators for sound control and dual mufflers.

At idle the STILLEN Exhaust is unobtrusive, however when pressed, STILLEN's recognizable, trademark sound emanates. This is a pleasing tone, authoritative and yet responsible. Not only does this exhaust system have a sharp, show ready look, but it also has a long service life (lifetime warranty) and is easy to install.

An FX35 owner can further complement your new Infiniti FX35 exhaust system and engine performance with a STILLEN cold air intake (see part #402835) adding even more performance to your FX35.



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.
