    Diesel Truck Shiat - Per Cook's Request...

    As the title says, this thread is all about Diesel Shiat....Per Cook's request...

    im sure that more and more people will be getting diesels and this thread could become helpful...

    ill start...it may be a stupid question, but what is/where is the down pipe? Is this just the tube that is the exhaust side of the turbo to the ehaust? if so why would you need one with an aftermarket exhaust?

    sometimes the down pipe has been crushed, for a lack of a better word, from the factory. i know the older power strokes(97 and older) are like that. same concept as a y-pipe on a gasser.

    so is it the pipe that is the outlet side of the turbo to the exhaust?

    the outlet side of the turbo is the downpipe the reasoning for getting an aftermarket downpipe would be that you could decrease the back pressure increasing the flow of exhaust. thing to remember is air in air out. your greatest power gains without doing any kind of extreme hardware or electronic mods is increasing air flow. i suggest check out Bank's power elbow. if you do not want to put aftermarket exhaust on your truck just cut the muffler and spark resistor off of the exhaust system, that will be a nice power gain. if you do decide to go with aftermarket exhaust go with 4-5" nothing bigger. as for power in go for the afe air intakes i have heard alot of good things about them, i have a k&n stage 2 on my 01 cummins and it showed a little better performance but i have heard better things about afe. if you have any more questions on any other kind of performance email me @ zdocmeyer@msn.com and if i cant help you i will know someone that will.

    5in is a waste in my opinion, big rigs have been using 4in for years with no probems.

    Like Will said the best way to increase performance, gas mileage, and decrease egt's is to increase air flow. Most everyone I know with performance upgrades including myself run AFE intakes. I feel that they are the best quality for the price. As for exhaust I would stay with a 4" from the turbo back, that's the most common setup. If you go any larger you need to be putting out some serious power, I know a guy with a 4" downpipe into 6" straight back but it looks ridiculous.

    approx 700hp before a 5in is needed.

    You have to remember though, big rigs are running at 1500-1800 rpm and the pick-ups are 2000+ cruisin. Even with the smaller displacement you are lookin at lots of air needing to be moved out of the way. I recomend a 5" downpipe into a 4" system with some type of turbo muffler. If you want obnoxious, go with no muffler at all. I do "not" recomend removing your cat though.

    "not" can be read as "highly" in some peoples previous posts.

    is there any reason to go with a stainless exhaust over a aluminum one other then for esthetics? also is MBRP that much better then AFE exhaust system? the AFE one is cheaper for the same thing.

    My truck is pretty sweet. I have done a few mods myself.
    I did some mods to the air cleaner and installed a K&N.
    Adjusted the hood screws to let more air into air box.
    Installed a pryo and adjusted the pump.
    David Oliver helped me adjust the timing.
    3inch straight pipe. I really wanted to put duals on it but I did not have the money at the time.

    I think I got a 1 mpg increase it was sweet.

    I am pretty sure I can pull more than chadnutz too.

    Also when my truck is running it sounds like a pissed off 12valve.

    All of the research I did on the ford showed that MBRP put together a better engineered and sturdier product. There is a few MBRP dealers in H-town also that will install it. With the aluminum, you will never have to worry about rust, with the stainless it is not so bad but you will eventually get some at the joints from the rubbing.
