Re: What's a good "family friendly" performance muffler?
I just replaced a 20 year old exhaust(sat for 10 years in the garage) which had 40 Series Flowmasters. I too was over the 40 Series drone.
I replaced with the Magnaflow SS system 16643.
I am very happy with the Magnaflow system.
It was quite challenging as far as installation, but the it really quieted down the exhaust noise in the cab.
I cannot address what it sounds like out of the truck during acceleration, but I am very pleased.
Engine is a stock 305, 258hp with rams horn manifolds. Downpipes are 2" aluminized steel.
Original system was 2 1/4" true duals...no H or X pipe.
New system is 2 1/2" with an X pipe.
I seem to have better low end acceleration and a bit more top end speed.
