2015-2020 F-150 Flashark Exhaust Preview: Mild to Wild on a Budget (No Drone)Upgrade your 2.7L, 5.0L, or 3.5L 2015-2020 F-150 with a Flashark catback exhaust. So, like many F-Series owners, you need a catback exhaust to wake things up a little bit. Or you could save yourself a whole bunch of money and check out a Flashark Racing catback exhaust. Flashark is relatively new in the performance exhaust world, blending affordable pricing — shocking in 2026, I know — with bolt-on/no-cutting-necessary stainless steel exhaust systems with mandrel-bent tubing and polished mufflers. The Flashark systems are audible, but don’t sound buzzy as presented.
