    This was a perfect way to tone down the noise. The person who had it before me had removed the mufflers and resonator and only had an x-pipe. Way too loud for my neighborhood lol. This brought the noise level to a nice grumble but still a good volume to keep the excitement going!

    This is the iconic muscle car sound I fell in love with as a kid. I had previously installed an h-pipe resonator delete. Replacing the stock mufflers with the American Thunder package has improved the look and performance of my 2020GT PP1, and provided the exhaust note that I was hoping for. I’m thrilled with this purchase! Took almost two hours (measured 5 times, cut once)and the fitment is perfect!

    Looks good, sounds good, fast. Shop did a wonderful job and would recommend them. Very professional and quick.

    Quality made product. Easy to install, added power and sounds great. Just what I was looking for.

    Quality product. Lots of padding in box. Exhaust tips are welded on. Easy install and they sound great! Took maybe 90 minutes by myself with basic hand tools.

    I already had these on my car and loved them. It was time for new ones. The old ones did not come off easy, but the install was easy.

    Looks great I love the size of the tips and the sound it makes is just amazing!!!!

    On my ‘07 Shelby gt mustang. Went from stock to these….an instant wow!!!! Love ‘em. Not too extreme with loudness, not too raspy….classic muscle car sound! I only used a socket set and torque wrench. Easy install!

    haven’t really been able to get the full effect car is still being put back together, but I have a convertible and it is considerably louder. but as of right now I don’t have the top on and the back seat is removed so there is no insulation from them. install was a little tricky, there were a couple bolts that were difficult to get to. but have some patience and WD40. new ones fit perfect.

    Had to replace mufflers from a competitor that literally fell apart on the car. These flowmasters are definitely well made and have a great sound.
