"I purchased the American thunder exhaust kit for my 2011 Inaugural Challenger 6.4 HEMI. I took the car to local exhaust shop dropped it off at 8 am. They called me shortly saying it was done and sounded great total installation $105.00 and fit perfectly. I went to pick up car and the staff followed me out to hear it again. I used my remote start and from the first fire knew this was the sound I wanted. It has a very deep aggressive sound. Getting on it going down the road turns every head and sounds like a race car. Very happy with the exhaust! I don't really like the exhaust tips but will be painting the inside black. Just is new and can see the welds."

"This is a great product. I didn't know it was just a rear axle back exhaust system. Regardless, great high quality product."

"I could not envision a better exhaust system to give the desired sound I wanted, especially out of a 3.6 L V6 motor. I own a 1996 Chevy Impala SS that has Flowmasters on it as well and though it cannot compare to the rumbles of the 5.7 L V8, the Camaro definitely does not sound like a punk anymore."

"Placed this one my 2010 Carmaro SS and couldn't be happier. It have the exact tone I was looking for, something that would have an aggressive sound yet not ear splitting. You can hear the pipes in the car and yet still have a conversation or listen to the radio. CAR ID also had great costomer service, polite and very help full. I recomend this site and most of all this exhaust system. "

"it took me about 3 or so hours to completely remove the factory exhaust and install this kit on my 2010 tacoma. however this was also the first exhaust anything i have ever done. the instructions were easy to follow however and explained every step in clear detail. kit sounds amazing especially when you upgrade the intake like i did. truck sounds like a Hoss now even with it being just a V6 4.0 liter engine. ;)"

"Great product and sound, really wakes the car and neighbor hood up. Has some pretty bad drone in the car at 2,000 RPM and steady at 50 MPH but for us this is not a daily driver so I love it. I've had people stopping me in parking lots to find out what kind of exhaust I had because they loved the way it sounded. If it's your daily driver, I would go for the 50 series flows instead of the 40 series but if you want to turn heads go for this kit. Also at 60-70 MPH it really quiets out so a long trip isn't a problem unless speed limit is 50 the whole way."

"I have a 2010 Dodge Ram Quad Cab 8 cyl. 4.7L Engine Truck and with the help of CARiD.com, I have transformed this truck into a top of the line Muscle Truck. I purchased this Flowmaster American Thunder Kit and teamed it up with AirAid 301-232 Cold Air Dam Intake System, also purchased from CARiD.com and my truck sounds identical to a Ford Shelby and/or the Cobra. There is a tiny bit of gas mpg increase but the torque and horsepower increased by a lot; very noticeable and the two products combined, make an awesome sound. I recommend the purchase; I'm very pleased."
