"All i can say, is that everytime i start my truck and take off ; It gives a beautiful mellow sound that puts a huge grin across my face. It was exactly what i wanted, i got the delta flow cuz I didn't want it to be super loud but have a mellow sound. And it matched the sound i was looking for. Also gave better acceleration on highway up hill and don't have to downshift to fourth as quickly. not sure about milage, I love the sound so I kinda have a heavy foot for the gas pedal. all a round its an awesome product and i'm very happy to have purchased it!!!" —Treston S from East Wenatchee, WA bought a Flowmaster 40 Series Delta Flow Mufflers for a 1991 Toyota Pickup.
