1999-2003 F250 & F350 Heartthrob 4" Dual Exit Turbo-Back Exhaust System HT-4044555

No-Frills Power

The hearty 7.3L Powerstroke in the 1999-2003 Super Duty continues to prove itself as a reliable and strong engine all these years later, but we're pretty sure most owners wouldn't mind some extra pep in its step. With Heartthrob's 4" Turbo-Back, you won't only hear the difference in power with the kit's low, throaty growl, but you'll feel the difference with improved fuel economy, lower exhaust gas temperatures, and better horsepower and torque output too! If you're looking for a great-sounding and effective exhaust system, but aren't looking for the fanciest-looking kit, we've found your solution in the Heartthrob 4" Dual-Exit Turbo-Back Exhaust System. You won't find any polished tips with flashy embossed logos here, instead Heartthrob manufactured a simple yet remarkably solid turbo-back exhaust system with a high-performance muffler that gets you serious gains in power and efficiency as well as a moderate yet rich exhaust note to top it all off.

Solid 4" Aluminized Tubing

Heartthrob designed this Single Exit Turbo-Back Exhaust System with larger 4" tubing to provide optimal exhaust flow for better performance and efficiency across the board, and the larger diameter tubing also allows you to throw down some decent power upgrades without worrying about your exhaust gas temperatures getting too high. For trucks with moderate tuning or modifications, this kit's larger 4" diameter and included 4" down pipe are perfect for handling the upgraded power output. Better yet, this exhaust kit includes one of Heartthrob's high performance mufflers to squeeze out every bit of horsepower and torque you possibly can while producing a clean and refined exhaust note. This exhaust kit has been mandrel-bent by an exhaust technician out of a high-quality aluminized steel in their Minnesota facilities, ensuring flawless fit and function every time. Heartthrob also includes all necessary pipes, hangers, clamps, hardware, and detailed instructions for a complete and painless installation process.
