Give Your Mustang A Thunderous Exhaust Tone

The 2018-2023 Mustang GT gets a great new roar with the Flowmaster American Thunder Axle-Back Exhaust System. Flowmaster's American Thunder 3" Axle-Back Exhaust System was specifically developed for the Mustang owner who's looking for a loud, raspy and aggressive sound. This kit is easy-to-install and pops on right in place of your stock system with a dual split rear exit and 4" polished stainless steel exhaust tips that add the perfect custom look.

Increased Overall Performance And Lower EGTs

It's a sad fact that stock Mustang exhaust systems come from the factory with plenty of restrictions and issues that need to be addressed. Adding Flowmaster's Axle-Back Exhaust not only increases your horsepower and torque, but you'll also notice an improvement in fuel economy. With its mandrel-bent, stainless steel, 3" pipes and Outlaw series mufflers, this system pushes hot exhaust air out of your system quicker and more efficiently than stock, lowering the higher EGTs you'll experience at higher RPMs.

System Features:

• (2) High-Performance Outlaw Series Mufflers
• 3'' Stainless Steel Tubing
• 4'' Polished Stainless Steel Tips
• Dual Split Rear Exit
