I have a custom built autocross (VD RF84 front, sports racer rear with lots of downforce) car running a GSXR motor. This weekend one of my header primary tubes cracked and split. I have no idea on the origins of the header as it was on the car when I bought it. Previous owner/builder says he doesn't know either as it was on the engine when he bought it.
I'm going to see if I can get it welded, but I'm not very optimistic given the extent of the cracks (and it's ceramic coated). Does anyone have any suggestions on affordable sources for headers (or custom tubing that could re-make the cracked primary tube)?
It is a right side discharge with 1.375" ID tubing primaries, 4-2-1 slip-on collector with an integral 45 degree bend incorporated into the exit of the collector. Sound familiar to anyone?
Thanks for any information
Kenton
