Product Description

Flowmaster announces the release of our new kit for the 2005-2010 Ford Mustang GT. It features a pair of specially-designed 5" X 10" mufflers, which provide minimal interior resonance while delivering a deep and aggressive exterior tone. Through extensive testing this kit has shown some horsepower and torque gains. Features polished tips with Flowmaster embossed logo.

This aggressive sounding system is designed to replace the original rear mounted mufflers located behind the rear axle. With easy fit in mind, the system is mandrel bent for maximum performance and includes specially selected mufflers to support the performance image of the car. As an American Thunder system, it delivers an aggressive exterior tone with moderate interior sound level that is suited to the enthusiast who wants their performance to be heard. Like all Flowmaster systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, the system does require cutting of the factory system and includes all necessary parts and hardware for easy installation.

    5 Stars   Great axle-back system!!
    By on 2/4/2015
    I got the Flowmaster American Thunder system a few weeks ago to replace the stock mufflers on my 2005 GT. When they first came in, I thought that they were the wrong ones, due to the fact that the box said "Force 2". After some part number, however, I found that they were actually the same exhaust mufflers. The installation of the mufflers took me about 2 hours due to the amount of time the stock mufflers had been on the car. I chose not to use the clamps that came with the package, so instead I used the band style exhaust clamps that I got from autozone. After the first start up, I instantly noticed a huge difference in the deepness of the exhaust note. On the test drive I also noticed that my shifts seemed to have a little more power. Overall a very good product and they look great and really fill out the cutouts in the bumper. I really recommend picking up a set of these exhaust systems!

    I recently put these on my 06 GT Convertible. Easy to install yourself. The large tips look great coming out the back. Great for every day driving.

    I just bought these never been happier! If your looking for that rumble and not raspy tone these are it by far. I replaced my pype bombs with these no more raspy sound and with long tubes and no cats it sounds like a beast! This sound has heads turning ever which way I love it! Best buy ever worth the extra cash because they are that much better!

    I bought these since I wanted more of an aggressive sound but also where I don't annoyed the neighbors. It's fairly easy to install but the hard part was aligning the tips.

    I LOVE this exhaust. Just changed it last night. It has a great low moan to it. It's not the loud raspy sounding exhaust and doesn't have popping and other noises. It's actually pretty quiet in the cab and not overly loud outside the car either. If you want a deep low growl, this is your exhaust.

    This is a great product for the money. The fit was a little challenging. With a rusty OEM system, loosening all the hangers to get the right centered fit in the cutouts required a trip to Midas. Midas only charged $30 so now they look great and sound awesome.
