    alec296 i need another buick

    Tailpipes won’t work well, and are shorter.
    The pipes from exhaust manifolds to mufflers will probably work but will need to be lengthened.

    Nice can't find a system in sweden to Lesabre .
    I was going to take the first tube, extend to the rear axle and straight out behind no mufflers.
    Do you think the bend over the axel woke out?
    run with single straight pipe just a small silencer just crusin and have good ear protection like a good stereo lol

    Du kan købe rør der kan clampes sammen, i Biltema.. De har også ophæng, lyddæmpere osv.. Der findes også bagtøjs bøjninger, som slår et loop over bagtøjet, og ender i lige rør igen..

    You can buy tubing, that is meant to be clamped togtheter in Biltema, they've also got silencers, brackets and so on..

    Know, but what I need most is the pipes from the manifolds and down. Have y-tubes that are rubbish.
    Will probably fix it somehow, there is a problem for finding solutions.

    when I have new downpipes and the bended pipes over the rearaxel

    You can probably make the system work you will just have to add extension pipes from muffler to tail pipe. May also need to add extension pipe from front to mufflers too.

    It might be easier to have a shop custom bend you a system... I just did this on my 2012 gmc and custom bent was a great fit and low cost.

    they never made duals for the 350 engine, only 455.
    you could use walker exhaust p/n's
    2 of 43397, tailpipes
    1 of 43315, over axle p/side
    1 of 43500, over axle d/side
    2 of 21617 mufflers
    front pipes will have to be made or possible front pipes of 70-72 gs 350
    1 of 46270, p/s
    1 of 47341, d/s
    check with Waldron exhaust in Michigan I think

    Talked to a local guy and we take the GS 350 first pipes ,

    make them a little bit longer.Then there will be a wildcat system the rest.
    Hope it works Merry Christmas guys

    A H balance tube or X pipe might help performance alittle. And with duals from single exhaust could use a jet up in carb since air flow will improve. Could probably at 2 degrees of timing also.

    Trix and fix.
    newly renovated, 0.30 drill
    10: 1 pistons and comp 268 h.
    73 bottom and heads from 68 distributor 1111260 think it is 30° advance have to check. have an extra 1111334 , some one wants to be rebuilt .
    Works well, but better when i removed muffler and silencer. Has set the ignition at 6 °

    That cam really perfers headers to work best, it needs the extra scavenging . Straight pattern.
