Support

[Johnny]

I don't remember if this has been discussed or not.(probably has) I sure don't want any cracked or broken headers in my future. Does anyone know a way to make supports for my sidepipes? The headers and sidepipes don't weigh that much, but after time and bouncing up and down they could crack or break. (I think)
Yes, no, maybe on supports???
Thanks

If it was a problem, somebody would make and sell them already

They would have to move with the engine and not fixed to the frame.

Well, thanks a lot!

Yes, I know that.

On some road racing cars, what we would do is to cut a tube so it would saddle the exhaust pipe and then stretch 2 springs over the top, then a support tube from the saddle to the frame

Here is the way that I supported my headers. They are rubber mounted and do an excellent job.







I can not see letting them hang out there with no support. You are only asking for problems down the road.IMHO

Plate sandwiched between the trans. & mount , 1" square tubing side to side , took out "some" of the vibration [+ makes me feel better]

Jim,
Are those bolted to your frame? I can see what the front support is bolted to the muffler. Did you just drill and tap the rear attachment point on the muffler? Where did you get them, and how thick is that rubber biscuit on the supports? Looks very nice.

Thanks,
Johnny

Got a good photo of your mounting system??

Thanks,

Yes, they are bolted to the frame. My frame is 3/16" thick so it is tapped for the bolts. The muffler part of the system is attached with a clamp type of set up so I just installed a longer bolt to accommodate the mounting of the brace. The rubber pieces are 1 1/8" diameter by 1/2" tall. These have been on my car for over five years and close to 16K miles with no problems.

Thanks a lot on the info. I'm pretty sure I can do that.

I don't know where to find them but I have seen electric motor mounts that have 3/8x16 bolts bonded to rubber dampers for shock mounting that would be just the ticket for this application.

Heres another way

Mine broke around the header flanges once, eventually made a small rubber mounted support towards the back of the pipes. never had a problem after that. That's a lot of leverage on the header flanges hanging out there, in the breeze, bouncing down the road. No point in tempting fate too much I reckon.

The first summer I ran them without supports, with the heat and the bounce, they dropped about 3 inches at the exit. To create the supports, I used some 3/4 tubing bent it to match the drop. Instead of using a rubber mount, I slid a piece of 3/4 heater hose over the end and bolted it to the frame.

This was during my "Header correction" when I bent the headers to fix the droop.

Went from this:

To this:

With out the supports, it would just drop back down.
