    Default Straight Pipe or Cutouts ???

    well its time for an exhaust change and i cant decide between just cutting the exhaust right behind the cats... or (the more pricier option) doing a cutout with an electronic switch
    anybody doing these?

    Depending on which truck it is, on some u need the extra pipe for back press.. or the engine will actually be very low on tourge !!!

    There is nothing I hate more than the noise of straight pipes. Some trucks sound like a machine gun going down the road. It sounds cheap. If you add electric cutouts, get a nice set of headers. The headers will totally change the way any engine sounds for the better.

    Check out my old chevy with open headers.

    Personally I would do cutouts so that you can open them when you want to. Sometimes you wanna be a little quiet and others not so much, it will be like having two exhausts and when you get pulled over for being too loud, just hit the switch and tell them they have the wrong truck

    I agree with daredevil.....I had a buddy with an ford ranger and ran straight pipes and it sounded like a pissed off mosquito. Then another friend had a Z71 5.7 L 350 with straight pipes and he would rattle glass as he went down the road. It was a bunch cooler back when I was young.
