    I'm putting a dual system on my jailbar truck.
    Cheap steel headers to 2 bolt flanges then to a pair of steel pack mufflers. I would like to fit some simple cutouts just towards the back of the front fenders.
    Could I just fit a t piece with s removeable flange(maybe 2 wing nuts) would I need to have a way of then blocking off the gases to the main system? Don't want it to sound like I just have a hole in the exhaust!
    It's just a stock flathead so not real noisy anyway

  2. Is this what you are looking to do?

    California Bill's Ford Speed Manual, 1952 edition, suggests this exact thing.

    Ian - he is talking about rat rods. Abbreviated because rr's are about the polar opposite of what this forum is about.

    No it doesn't. That's a perfect survivor look and great patina! RR is when people do things that can be unsafe or just to get attention like spider webs on the grill and stuff like that.

    I'm keeping that look, might have some lettering on the doors for my electrical business. Am lowering it all round, brakes and suspension all standard but reconditioned, has nice period recovered seat. Just fancy a nice old school dual system.
    What else might have been done in the 50,s

    So how do the tax laws in the UK work. Can you write off the cost of the truck as advertising for your business? So many of the door lettered trucks are fake for "the look", it will be nice to see a lettered up truck for an actual business.

    Good looking truck, well used, well preserved.
     
  20. Yea, because we NEVER do anything to our cars to get attention :rolleyes:

    Cutouts are illegal (the cops can give you a ticket) but it is not illegal to connect your headers with a flange. You can take the bolts out of the flange, move the tail pipe to the side and put one bolt back in (old drag racing trick).

    You can make cutouts using gas tank filler pipes and gas tank caps, but make a new gasket out of asbestos or heat proof material.

    Have also seen headers that terminate in old oil filter housings. Remove the lid to uncork the noise.

    Manual and electric cutouts available from Summit and other places.

    Here is the cutout on my coupe. There is a flange on the end of the headers, then it wye's into the mufflers and the 35/36 drive shaft as the exhaust that can be seen. I have welded nuts into the inside to screw the caps to.

    I would think that the header pipe should have the cap at the end, and the muffled pipe should Y off the header pipe. Then the open race pipe is a straight shot, and the street pipe has the slight restriction and not verse visa.

  25. Yep, they only ran gate valves for cut-outs on rat rods like this one in the late 40's...

    Another old way is black pipe nipples with either OD threads and caps or ID threads and plugs
