The MagnaFlow INFINITI Q50 Street Series Cat-Back Performance Exhaust System brings out the personality of your 3.0L, 3.5L, 3.7L INFINITI Q50 with our signature resonant, powerful engine tone and dyno-proven performance. Thanks to its fast-flowing, mandrel bent 2.5in. main piping and 3 Straight-Through mufflers ending in a Dual Split Rear exit with 4.5in. Polished Welded-On Double Wall Angle Cut Folded Edge tips, this INFINITI Q50 exhaust kit has the performance chops to match its sporty sound and appearance. Upgrade your ride to the next level with an exhaust that has the pipes to put other INFINITI Q50's to shame. With this system your vehicle will be producing Moderate exterior and Mild interior sound levels while leaving other cars and trucks feeling envious at every stoplight. Exhaust kit 15310 features a cat-back layout that replaces your ride's stock exhaust components from near the catalytic converter on back.

Customer Reviews (5.0 / 5 · 5 reviews)

Jacob ★★★★★

The deep, aggressive tone at startup is exactly what my Q50 needed to feel more alive. Install took about an hour with basic tools, and there's zero drone on the highway.

Steven E. ★★★★★

Finally got this on my Q50 and the cold start rumble is exactly what I was hoping for — deep but not obnoxious. The 5-inch double-walled tips look aggressive without sticking out too far.

Adam ★★★★★

Installed it over the weekend and the resonant tone at cold start is addictive, but it's the highway drone-free cruise that sold me. Fitment on my Q50 was spot-on, no modifications needed.
