"Muffler was very easy to install. Excellent sound and performance. Gas milage seems to be a little better due to the less amount of restricition of the muffler. Sound is a little loud but only if you really stand on the throttle pretty heavy. Would highly recommend to anyone that wants more milage and better sound.Add a cold air intake system as I did to get even more milage and performance. AFE or K/N cold air intake can also be purchased from AUTO ANYTHING" —Denny R from Littleton, CO bought a Flowmaster Super 50 Series SUV Mufflers for a 2004 Chevy Silverado.
"My 2004 Silverado had a dealer conversion Flowmaster exhaust system. The muffler needed to be replaced at 105,000 miles. I was able to get an exact replacement because Flowmaster bothers to engrave part numbers on their mufflers. It doesn't get any easier than that. Everything fits the way it should. I also love the sound." —Jon K E from Stewartstown, PA bought a Flowmaster 50 Series Delta Flow Mufflers for a 2004 Chevy Silverado.
"This muffler is badass, adds the perfect agression i needed for my truck, low interior sound, but an agressive loud and powerful sound on the outside, definatly a head turner, this is on my 5.3L V8 it sounds SO GOOD!" —Patrick H from Snoqualmie, WA bought a Flowmaster 40 Series Delta Flow Mufflers for a 2004 Chevy Silverado.
