Flowmaster Exhaust Reviews

Eugene S from Roaring Spring, PA says:

Better quality than I thought it was going to be. Took longer to install than it should have (broken nuts at cat) rest was pretty good! Tip bolt snapped when tightening! Quieter than last exhaust but a nice low growl. Read more Flowmaster American Thunder Exhaust System customer reviews.

Aaron F from Gilbert, AZ said:

Awesome sound which is exactly what I was looking for in my Chevy Silverado 1500. Sound difference was night and day. My neighbors no longer need a morning alarm! Street legal. Only draw back I see is the price. It's expensive. But I'm happy with it and if you have the money to drop on it you won't be disappointed. You do get what you pay for with this. Don't use the clamps get it welded at an exhaust shop or someone that knows what they're doing. I installed it myself and I'm not that good with car stuff so it's fairly easy if it's your first time. Recommended! Read more Flowmaster Outlaw Exhaust System customer reviews.

Package arrived right on time and looked well packed, fit my truck. Sounds mean! Only problem was I needed a couple of hangers that broke of my truck, could have thrown those in, guess that was my fault. Nothing a weld can't fix.

Jack from Somers, CT said:

I was searching for the perfect exhaust for a few weeks and found the American Thunder Cat Back to be the cheapest, yet best reviewed product I could find online. After installing it I found that my power gains and sound was GREATLY improved. I drive a 2007 Chevy Silverado 5.3L V8, and the exhaust really woke up the engine coupled with a Spectre cold air intake I bought as well. The cat back is NOT LOUD so if you're looking for a crazy throaty sound this isn't for you, but putting your engine above 2000 RPM's does make a pretty mean sound. This being said it is the perfect modification to make me and the girlfriend happy, and we can still keep a conversation in the cabin, unlike when I had a monster of an exhaust and you could barely hear the radio. Overall rating is 10/10 if this meets all the specific requirements you are looking for.

Bilie G from greenwood, SC says:

I love them. They make my Challenger R/T actually sound like a hot rod now.

JIM A from Boise City, OK says:

Quality exhaust, although didn't care of the left side exit, too close to rear end cover & filter plug. Shipping was prompt.
