STILLEN Axle Back Exhaust for 2014-2015 Infiniti Q50 Sedan V37 - 504442 STILLEN has long been associated with Infiniti performance parts. Year after year we apply our expertise to create power-boosting, style-enhancing products befitting the stature of the Infinity marque.

Take our meticulously crafted exhaust systems. Proven to produce the maximum horsepower possible, STILLEN exhaust systems also enhance engine note with the perfect balance of sweet and snarl.

The STILLEN Q50 axle-back exhaust system is no exception. It commands attention with an aggressive tone under hard acceleration. Less pedal pressure yields a mellower engine note - perfect for driving your mother-in-law to the opera. It's that signature STILLEN symphony that Infiniti owners rave about.

The free-flowing performance mufflers and tips are hand-crafted here at the STILLEN facility using top grade 304 Stainless Steel. An updated design makes installation easier than ever, while the piping is mandrel bent for unimpeded flow of exhaust gases. We're so confident of quality and durability, the Q50 axle-back exhaust is protected by a lifetime limited warranty.

Oh, and thanks to STILLEN design enhancements over the stock system, you can expect enhanced MPG at cruising speeds. Even your mother-in-law would approve! Made in U.S.A.
