My, my, why am I surprised to see a snide remark for no benefit to anyone. :D
Okay, so is this car custom? I fabricated it from the ground up starting with 400 feet of steel tubing. The only 2 original parts are the front nose, and the windshield frame. All of the interior/exterior sheet metal was fabricated from flat sheets. It is the only one in existence, and I couldn't duplicate it Attachment 7644Attachment 7645again myself.
I agree with Nick that the h-pipe brace is a bad design as-shown, but for a different reason. When the exhaust pipes heat up they expand. The h-pipe needs to be able to move rearward to accommodate that expansion. If it can't move, it will stress the pipes.headers and with repeated thermal cycling something is probably going to crack.
A couple ways to address this....one, put expansion joints in front of the h-pipe. Or use Deeds clamps like Nick suggested or some other exhaust hanger that allows movement longitudinally but not laterally. That allows the pipes to expand and move freely. Also, it looks to me like he's never going to be able to remove the exhaust pipes from the frame....but maybe he never needs to. ;)
This is how I solved a similar problem with Deeds clamps:

He still doesn't understand that the discussion was about "custom parts", not custom cars. But as usual he changes the subject.
If you go back and read the thread, BN said there were lots of custom parts on the chassis (that's how I read it anyhow). I asked what was custom on it because I like to see custom parts people make, and RD has to chime in with his views on what constitutes a "custom CAR", taking the thread off on a tangent like he always does. Let him argue with himself. :D
Thanks again for the kind words, and setting the example for proper forum etiquette. I was never referring to custom cars, only that a custom car is composed of many custom parts made, or restored. I only used my car as an example, because that is exactly what I tried to do, was hand make as many, and most of the parts of the car including most of the body parts, each piece of steel, and every other part used to create the car on the fly. It was only about $15k in money, and probably 3-4 thousand hours, many of which was spent just trying to figure out how to create a car from SCRATCH!!! Too much money in a car always decreases most of the fun of building a car, and the time spent on it is priceless.
I figured that following the rules - good manners and treating others with respect wouldn't last forever here. A real shame.
