    The STILLENŒ¬ 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 STILLENŒ¬ symphony that Infiniti owners rave about.

    The free-flowing performance mufflers and tips are hand-crafted here at the STILLENŒ¬ 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. W're so confident of quality and durability, the Q50 axle-back exhaust is protected by a lifetime limited warranty.

    Oh, and thanks to STILLENŒ¬ 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.
