    Hello Y'all,
    Just bought my first diesel. A 88 7.3 f250.
    First question I got is what affect would straight piping have to my truck. Somebody told me it would make my truck super quiet and another that it would make it sound great.
    Second question is are there anything's I can do to improve mpg besides keeping my rpms below 2000. Thanks

    Technical section all information like that some say turbo it keep a non lead foot helps, welcome to Oildburners pictures of truck.

    Straight pipe helps air flow but a diesel is a diesel it will be loud

    I'm also new to owning diesel power, it is also an '88 7.3 IH-IDI Ford.
    IMO: Diesel motors purpose is work reliably, efficient/ pound/ mile. My thought on open exhaust is potential damage from relatively cold air being drawn back into the engine when shut-off.
    Have you considered the Legal aspect of removing the exhaust -muffler? I see your not a California resident, but you would never get in w/o muffler. LOL

    Ok thanks.
    I hadn't thought about legal aspect some of my buddies have straightpiped theirs and the truck I use for work is straightpiped but they're all turbos.
    I don't have any plans on coming to Commiefornia though lol.
    What mpg do you get on your 88?

    Just straight piping your truck will make it sound faster but in all
    reality there will be little to no effect. Much like flipping the air cleaner lid
    back in the old days. 50yr olds know what I'm talking about. :)

    Secondly, Your fuel mileage is controlled solely by your right foot. Not a tach.

    Welcome to the forum. :cheers:
