The Flowmaster Sound is the true tone of American muscle and performance. Available in a wide range of domestic and import applications for automobiles and trucks. Flowmaster mufflers produce more power than OEM and competitive aftermarket products.

This American Thunder exhaust system is the loudest in the Flowmaster Exhaust System Line-up. This American Thunder exhaust system has been individually engineered and dyno tested with the latest in technology. Through this technology you will experience improvements in acceleration, passing power, and fuel mileage. The key to the system’s performance improvements is through the use of mandrel-bent tubing that allows for superior exhaust gas flow. Aluminized steel tubing has been used for its corrosion resistance so your system will last. The American Thunder system comes with a two-chamber muffler that will give you plenty of aggressive Flowmaster sound outside the vehicle as well as inside it. Every kit comes complete with all necessary hangers, clamps, and mounting hardware for an easy installation.

I have the 1lt (base vette non npp exhaust). Installed this part yesterday evening with a friend. There is a video on youtube that was for another manufacturers larger system that helped with removal of the bumper and factory exhaust. On the way to work got a check engine light. Flowmaster is aware of the issue and is going to have me speak with R&D tomorrow!

I watched countless YouTube vids of axle backs for my car. Let me say they're essentially useless! Based on the videos I had my heart set on a ford racing or borla touring exhaust. They seemed to have the deep sound I was looking for without being obnoxiously loud. I was avoiding the flowmaster setup based on a few videos that made it sound too high-end and not rumbly. I was set to spend 700 on the borlas but stumbled on a vid of the flowmasters that sounded good. So I decided to risk it to save some dough. I'm not disappointed. I put them on in under an hour. The fit is stellar. So easy to line up in the valence, looks great! If you're looking for a crazy loud system this is NOT for you. It's not much louder than stock, but has a much beefier sound. There's no drone in the cabin unless you really are looking for it. At cruising speeds with the radio on you can't hear the exhaust. Dip your toes into the gas tank and it roars pretty good, but again nothing obnoxious. I think it's perfect for a daily driver.
