2015-2017 Mustang GT 5.0L V8 Flowmaster American Thunder Cat-Back Kit 817730

Performance V8 Mustang Exhaust With Aggressive Sound

The new 2015-2017 5.0L V8 Mustang looks impressive and if you're lucky enough to call one of these bad boys your own, you're going to want an exhaust system that can give you a sound to match those great looks. Flowmaster has a great option with this American Thunder Cat-Back Exhaust System which not only gives your Mustang a moderate-to-aggressive growl when you hit the gas, but also increases your already awesome horsepower and torque while delivering you even better fuel economy results. While this high-performance exhaust has a more raspy race car note when you rev the gas, it's performance oval mufflers ensure that there's minimal interior drone while delivering you all of the results that let everybody know you Mustang means business.

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 a high-performance system, such as this Cat-Back Exhaust not only increases your horsepower and torque, but you'll also notice an improvement in fuel economy. With its mandrel-bent 3" pipes and performance mufflers, Flowmaster's 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.

Durable 409 Stainless Steel Construction

Like all of Flowmaster's Cat-Back Kits, the Mustang GT American Thunder system is extremely easy to install and is manufactured out of mandrel-bent 409 stainless steel. The oval mufflers and 3" tubing are black powder-coated for anti-corrosion and look great, while the 4" tips are polished 304 stainless steel and look mean coming out the back of your ride. The kit frees up some of the back pressure caused by the stock exhaust system for minor power gains on top of the new, cool sound.
