i just got a 04 f250 5.4 reg cab and was wondering what people are running for exhaust and what options there are

 

I cut my muffler off and replaced it with a piece of flex tube. I love the sound and it only cost me about $20 for the tube and 2 band clamps

 

I have a 6.0 and I had MBRP cool duals installed. They are 4" pipes exiting each side with 5" tips. It does draw some attention to the truck.

 

I just did a turbo back Magnaflow on my 6.0, sounds fantastic and helped with the lag a little. Seems to be a tad quicker as well, but this is the only mod I have right now. Next is the cold air and the chip.

 

Hey Niceguy,
Did the new exhaust make the turbo whine much louder than stock???

I had my new exhaust and AFE Stage 1 kit installed on the same day so I do not know which modification caused the turbo to whine so much louder (Really sounds cool and everyone notices that sound!!!)

Cheers,
Lee
