2007 GMC Sierra Crew Cab 5.3

Reviewed By Randy L (EVANSVILLE, WI) Reviewed for a 2007 GMC Sierra —9/22/2015 5:45 AM

I like Flowmaster exhaust so I bought the American Thunder Series and installed it, I like the idea that you have the option of running it straight out by the bumper or 45 degree angle like stock. It has a real nice deap muscle car tone to it which I really like along with the chrome tips that really look nice that set it off.

Honest Review

The exhaust itself is well made, sounds great, and looks awesome. I found the installation was hard. I installed it by myself, with my truck on ramps. If I had some help it would of been much easier. The only complaint I have is the clamps. The clamps are a band style clamp. They take a lot of wrenching to get them tight on the pipes. I will probably have a shop weld the pipes eventually.

Should have done this a long time ago.

Very easy to install I performed the install by myself only needed help for the end when I was aligning the tips. Sound is great not to soft and not overly aggressive just right. No drone when the truck drops into 4 cylinder mode which is why I bought this one. Cruising at highway speeds you only get a whisper from the exhaust note until you get on it then it lets loose. As far as fuel economy gains I can't tell since it sounds so good I have trouble staying off the gas pedal.
