Post Good Muffler

I'm getting my truck all ready to go, and of course that means new mufflers. What kind do you know of that would sound really nice and powerful on a 402. Thanks for your help.

I have the flowmaster 50 series. I am very happy with them. Nice low rumble when idling. Not too loud at cruising speed 3k@70mph. I highly recommend them.

Thumbs up

I have regular 40 seires Flows on my truck. They end above and infront of the rear axle, without turndowns. It is pretty damn loud, but sounds great . Really deep and throaty.

dynomax superturbos, cheap and sound good, they are fairly quiet, maybe a little too quiet but they roar when you get on it, worth it i think
