    Does anyone have a picture of the stock exhaust layout? Im trying to figure out what I should buy for my truck when its here, and Im not suree what will work best. Like will a hi-flow catconverter mess with and o2 sensors?
    I really would like to take the stock full exhaust off and buy after market headers, converter and exhaust so its easy to put back to stock when I sell. Any help would be awesome

    "High flow" convertors won't do anything. What year truck are you getting?

    Factory cats are already hi-flow.

    If you want a more aggressive sound, you can have a muffler welded in. Changing pipe diameter from the cats back will also help with that.

    What exactly is your goal?

    You're not going to get any power or MPG changes out of an exhaust setup without tuning the ECU, and that gets expensive.

    For sound, start with a muffler, and perhaps adjust pipe diameter from the cats back. Bolt-on catbacks make for the easiest solution, but are a little more expensive than just having a muffler welded in.

    Stock is 1.75" into the muffler, 2.25" out...I think. It's been a while since I had to dick with exhaust.

    Recommended? By whom? And for what? You can alter your sound a bit by twiddling with exhaust diameter, but that's really a matter of preference.

    Header and exhaust might get you 10hp max at high RPM.

    Well I forgot we were int he 4 banger section so maybe 7ish on a 4 banger. 7 horsepower for about $500 isn't that great of a turnout.

    Oh yeah. I agree but after deciding a truck will never really be fast I stopped with the "performance mods" and I'm saving for a car that will actually be fast.

    $500 for 7 hp you will NEVER USE unless you redline every gear.

    In other words, a complete waste of money unless the exhaust note change is worth that kind of cha-ching to you.

    Pretty much. If a blower was on the way like I had planned then you would get more out of those simple mods.
