Great throaty sound, not too loud, little cab noise but nothing that's bothersome. Had it installed at muffler shop to insure proper installation. Really opens up when I get on it. Very happy with price and quality.

I had a local shop cut the stock muffler on my 2011 GMC Sierra and had this installed. I paid 70 to have it welded on the stock exhaust pipe and could not be happier. if you have my truck you will need the 3" center inlet with 3" offset outlet. There is some resonance inside the cab but nothing crazy that will disturb your conversation or phone calls. could not be happier with the delta flow.

Sound level and tone from the exterior are perfect. Inside I have a bit of a harmonic drone around 1700 -1900 rpm range that is a bit too loud otherwise interior noise levels are about what I expected. This is my 3rd Flowmaster on as many trucks I'm sure it won't be my last.

This flow master has a very nice sound not too loud for my wife when she rides inside the cab of our 2004 chevy short bed v8, and I noticed an immediate difference in power and fuel economy well worth the price it would have been better if it cost less but... still worth it!
