"I was tired of the boring, quiet stock exhaust on my truck and wanted to wake it up a little without waking up the neighbors. The 50 series is a great choice if you want a deep rumble but want to stay friends with your neighbors! It has a deep, throaty rumble but isn't loud in cab all. Flowmasters do drone slightly, but this one isn't too bad. The center inlet/offset outlet fit perfectly in place of the stock muffler. Very happy with it overall and would recommend it!" —Dan W from Fond Du Lac, WI bought a Flowmaster 50 Series Delta Flow Mufflers for a 2002 GMC Sierra.
"This muffler was easy to install and looks great. Exactly what I was looking for of nice tone and loud but not so loud it will attract attention from police." —Nicholas B from Argyle, NY bought a Flowmaster 50 Series Delta Flow Mufflers for a 2002 GMC Sierra.
