More whistle

[Cjwilliams1182]

I've got an 04 f250 and I'm looking for more whistle. Any suggestions as far as performance parts?

[Jarrod B]

power max or 03 turbo

Straight pipe it

03 turbo + no muffler or cat strait pipe = all the whistle you can handle

He might already have an '03 turbo if he's an early '04. Do you have the resonator on the downpipe? Build date?

My straight piped '03 is pretty wicked loud and it still has the stock downpipe with resonator.

Just gutting the cat and straight piping my '06 has produced more whistle than I care to have, which is probably due to it being dumped before the axle. So being an '04 it will have plenty of whistle with just a straight pipe.

Thanks for all the feedback guys. My truck is an early 04. I found out the hard way when I had to replace my icp sensor.

if its an early 04 then straight pipe it now and youll be good to go.

Has anybody heard of problems with smogging the truck after going with the straight pipe?

If you could only do one delete, cat or muffler, and your goal was to get more whistle, which would be better?
