The MagnaFlow Street Series Crossmember-Back Performance Exhaust System 15816 enhances both sound and performance on your 1967–1970 Ford Mustang, delivering dyno-proven gains along with MagnaFlow’s signature deep, resonant exhaust tone at moderate exterior and mild interior sound levels.
Compatible with a wide range of engines from 3.3L to 7.0L, this exhaust system is constructed from durable, corrosion-resistant stainless steel, ensuring long-lasting performance and reliability. The crossmember-back layout replaces the exhaust system from the crossmember rearward, preserving classic fitment while improving exhaust flow and sound.
The system features fast-flowing 2.5-inch mandrel-bent main piping that routes exhaust gases through two Straight-Through mufflers before exiting through a dual split rear configuration. Finishing the look are 2.75-inch polished, welded-on single wall turndown tips with a cut edge, delivering a timeless muscle car appearance and tone.
Thanks to extensive 3D scanning during development, exhaust system 15816 features a direct-fit design that allows for easy do-it-yourself installation. Manufactured using CNC precision robotic techniques, this system is backed by MagnaFlow’s limited lifetime construction warranty.
