Al Colvin ....C &amp; C Reproductions circa 1987-90. Although these are done in S/S , They were off the Original GM Blue prints issued to 2 suppliers. One of which was WALKER EXHAUST.
These C &amp; C Components were nearly undetectable other than the material ... I'm not sure how many sets were made. He built both BB &amp; SB set ups with the head pipes being the only difference. The hardware and hangers were spot on too...
Myself and a friend were original investors and we each got the first sets available... mine for a SB Z/28 , his for a BB YENKO . (mine is still with me, under the car,,,, never been fired up yet)

maybe someone has a set mothballed ....

Update , The system discussed here, has been sold for use on a very deserving 69 Z/28.......
Price was north of $4,000 for those who asked and inquired.

Thanks to all with info and input in getting the facts aligned.
