Magnaflow Cat-Back Exhaust System
Application: Mazda 3
Part Number: 15861

It’s time to give your vehicle a new soundtrack. Not from a booming speaker system, but from something that will make you want to turn the stereo off: Magnaflow’s Cat-Back Exhaust Systems. You’ll discover that there’s nothing like rocking or grooving to the true sound of your engine.

Of course, Magnaflow Cat-Back Exhaust Systems offer more than throaty sound. Instant horsepower gains, abundant pulling torque, and a helping hand to improve your gas mileage are also on tap. Not to mention, the unbeatable performance looks of single or dual tailpipes running out your back end or sides.

Magnaflow engineers their Cat-Back Exhaust Systems to bolt on easy, giving you more time to cruise. All pipes are mandrel-bent stainless steel tubing from the flanges to the tailpipes. Magnaflow also throws at least one of their high-powered mufflers into the mix to complete the system. Depending on your ride, they even come in both single and dual kits for gas and diesel engines.
