"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."

"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 purchased the axle-back American thunder kit, aggressive sound level for my 2011 Camaro and I gotta tell ya this is the way to go. The sound is great and you are still able to maintain the needed back pressure. The price is GREAT and when I took them to my local exhaust guy he told me that was what he paid for them. Flowmasters are it!"

"Took a few days for the order to arrive. I took them to a local muffler shop and they were installed in less than an hour. Needless to say that the Camaro now sounds like a true muscle car. I had a 69 and 71 Camaro before kids. After 25 years of Mini Vans and SUVs now I enjoy the new Camaro. Like not seeing the stainless steel under the rear end, the performance and look is great. Will see if the mileage will improve in the coming months: without the new kit I was getting 27 on the road. The car looks and feels like a muscle car! Enjoy the new toy! Thank you for your excellent service and products!"
