I got a single chamber flowmaster on my 05 f150 scab.. dumped. It was a big mistake. the drone is freakin ridiculous. It sounds like there is 5 15" woofers in the back seat unleashing hell. how much of a difference is tail pipes going to make? or should i look into a diff exhaust? Anyone else encounter this?

 

Where is the muffler and where does it dump? You could move the muffler as far back to the axle as possible and dump it there or run a pipe all the way out the back. Or just get rid of the Flow, which is what I'd do. That muffler is going to drone no matter what.

 

yeah i know there is going to be some drone, and i am fine with a little bit.. It is dumped right behind the cab.. maybe a foot or two away from the cab. im probably going to run pipes out the back. hopefully that will help. what about resonators? if not flow.. what would you suggest? appreciate the feedback.
