Had my flowmaster muffler removed this weekend inside the cab on long trips was a killer the kids in the back seat had toi wear headphones to hear the radio. In the front wasnt as bad but still loud. I replaced it with the Flo-Pro Hd oval muffler dual in dual out very quiet on the inside little rumble on the outside.

I know the Flowmasters I had pretty loud. Mine had a "drone" that I got tired of.

You know you are getting old when the loud exhaust gets on your nerves,It used to be " man,that sounds cool! " now it's "can't you afford a decent muffler?"
