just straight piped
just straight piped my 2000 F350 and man does that turbo sound good. I rode home from the store with my passenger window down so i could here it.
one question though. is there any way to quieten the flutter with out quieting the turbo? i'd heard tips at one point will this work with the 3.5 inch exhaust.
for those out there going to cut out a stock muffler jegs has 4' sections of 3.5" pipe for $26 shipped
thanks guys

i got a dumb question now
i was coming to school (work) today. coming up a slight hill running about 1500 rpms and heard this whooshing sound from the exhaust that i'd never heard befor
when i mashed the pedal more the sound stoped is this my waste gate opening and flowing boost out the rear? let off whoosh and on nothing
would a bigger or smaller tip help the flutter?

Thats probably your EBPV kickin on. Usually kicks on when its cold outside and the trucks not warmed up. It makes a loud wooooosh sound, like a F16 staging at the run way. It was probably about 45 degrees this morning, and mine was on as it was warming up in the driveway. Usually it has to be colder outside before mine will also kick on while i am driving. Yes it does shut off by tapping the brakes or pushing harder on the gas pedal, but if the truck is still cold it will usually come right back on.
As for a tip helping the flutter, i doubt it. A bigger tip might reduce it a little, but its probably not likely.

By replacing the muffler with a straight pipe - does this help lower temps also. I know the guys who have changed there entire exhaust to a 4 - 5" say it lowered there EGT's. I'm guessing that staying with the 3.5" exhaust will lower the temps slightly - but not as much as switching to 4 - 5" exhaust.

lower egt's
the stock muffer is restrictive as heck and you would not believe how much quicker the turbo spools up and the egt's come down after just taking off the stock muffler
and it only cost me $26 and about 2 days work after supper

the ebpv usually comes on only at idle (from what i have observed). it is like a hissing noise, most noticeable at the tailpipe. you can feel that the flow coming out is less, that is because the butterfly valve is closed and there is only a small orifice for the exhaust to come out. this puts a load on the engine somehow, creating more heat, to warm it up. blipping the throttle usually kicks it off. if the valve stayed close at anything over a high idle, it could be bad for the components and engine. it stays on untill the computer has felt that the engine is warm enough. i have heard it on mornings before when it was 60* out. yes it may be 60* out, but it is still cold in that engine.

Mine comes on while i am driving, and sometimes i just barley touch the pedal so that is stays on and helps warm my truck up. I can hold 35 mph, keeping the ebpv on by barely touching the pedal. Also the high idle position(1300 rpm) on my chip causes the ebpv to kick on, i dunno why though. I will admit i am not real knowledgable about the ebpv and exhaust brake systems, but I doubt it would be too bad for the engine or its components, unless the valve is closed at a really high rpm or causing a lot of extra back pressure for long periods of time. I beleive its pretty much the same design as an exhaust brake. Many have even wired it to a switch, so it can be turned on manually for an exhaust brake. I drove a 2001 F-450 7.3L for work all summer long hauling heavy loads of galvanized pipe. It had the EBPV wired as an exhaust brake, and we used it all the time.
