    Sidepipe Location Question - without the body

    Sidepipe location with the body on has probably been asked a million times. How far from the body and how far from the ground. I want to ask if anyone had measurements for the sidepipes WITHOUT the body on the car? I know that I want the pipes to be level (bottom of pipe) with the round frame tubes. The question I have is whether there's a rough dimension as to how far off the 2 inch square tube on the side of the cockpit as well. I'm mocking up a header and the body is off for the next couple of weeks. Rather than wait until the body gets back on, I wanted to see if anyone has the measurements I mentioned so I can get the fabricator moving.

    Hey Scott. I wouldn't recommend doing anything until you have the body fitted. I suspect many will say the same. The body may/may not be exactly symmetrical to the frame. Especially on the left (drivers) side where the body needs to be pulled in/out to get the best door alignment. Since it sounds like you're having the headers custom made, I'd wait until you can get them exact. Whole bunch of variables there.

    If you are building your headers, not bolting on a pair that are made for your car then this may help:

    I've got my side pipes (Muffler Section) about 3/8" above the round tubes.
    An easy way to do the initial layout is to use a couple of very strait 2X4's wedged up to the 4" round tubes to get to a starting point.
    Make sure the mufflers are sitting on the 2/4's and put a piece of 3/8" to 1/2" plywood on top to space them upward.
    Also, you really need to know where the openings are for the exhaust exists because this is a process that works best with the body on.
    Regarding how far off the side pipes are off of the square tubes, I will have to measure that distance for you when I get home this evening.
    Finally, Mark Reynolds at Breeze Automotive carries some super simple, super cool adjustment wedges that you may or may not need.

    If you are using headers that are designed for the car, then wait to hang the side pipes after the body is on.

    What edwardb said. You can't nail down an exact sidepipe location until the body is installed and in it's final location with the doors fitted.

    I'm right at 6" from the inside of the square tube to the centerline of the pipe for both sides of the car.
    Also, when we fabbed up my headers the Body Was On so I'd suggest staying with that program.

    I'm on the band-wagon....name of the song is "Nothin Ain't Nothin Till the Body's on in the Right Place" Can't really dance to it but it's got a catchy hook...da bat

    Message Received. Wait until the body is back on. Should only be a couple of weeks, but I've got plenty to do between now and then. Thanks for the responses.

    For The Record Here Is How Your Respondents Stack Up Regarding Ability & Experience:

    Jeff Kleiner / Master Professional Builder & Painter
    Jeff "Da-Bat" Miller / Master Professional Builder & Painter
    Edwardb / Master Hobbyist Multiple Personal Car Builder
    GoDadGo / 1st Time Hobbyist Dark Side Builder

    If the three folks on the top of this list ever give you any advice, then my advice is to take it unless you are stuffing Small Block Chevy Power into your car. If you want to come over to the Dark Side then I can give you the measurements as to where to locate the engine, where to find the mounts and some affordable modifiable headers that will help you along if it is a Small Block Chevy or Chevy Style engine.

    Good Luck From The Dark Dart Side!
