    restricted pipe?

    ok just installde the pacesetter headers and ory, love em but it seems like the factory pipe from the y to the muffler is way to small.

    i do have a magnaflow and the inlet is bigger in dia. then the factory pipe, it was welded ti fit though

    the ory pipe for each side is bigger then the pipe they y into, so isn't this restiction, should it replace it with a big 3 inch pipe

    The mid pipe is around 2-3/4" or a little bigger. I don't think you will gain anything from going to a 3" mid pipe. If you find it neccassary,pypesexhaust.com has just the mid pipe in 3".

    its just weird to see the mid pipe where all 8 cylinders flow be smaller than the y that only 4 flow, if i did go bigger would it sound more throughtier or deeper

    or should i just not worry about it

    It will sound horrible and not have enough backpressure. Dont worry about it.

    I doubt it would sound any different, its not worth the money, When you start looking into heads/cam or a new motor then i would consider it but on your current setup it should be fine.

    i had the same question, so i went to my local muffler shop here in the city and the cut the squished pipe off and added a free flowing one in it's place. no real gains, but better flow i'm sure. due to it not being restricted.
