I think its 76 Bill. Im pretty sure its 30 years before whatever year it currently is. I remember my buddy was waiting for it to be 2004 so bad in 2003 because it meant his 74 chevy was smog exempt and he could stick a 502 in it.


oh btw CaliChevyV8 you might want to keep a tube of lube in your truck from now on. If a cop pulls you over and finds out you have an ORY instead of 2 cats then your out 2 grand right there...but if you can get away with it i would keep the stock setup and just swap them when it comes smog time. But you still run the chance of getting caught.

 

goto a muffler shop and get them to take a piece of 3" tubing and expand one end to 3" pipe. then you'll have a good slip fit. the pacesetters fit damn good with the 3" pipe over it. the ORY is just 3" tubing with expanded ends... just slip fit over the collector and put the stainless clamp over the fitting


btw tubing and pipe are completely different, tubing is measured by outside diameter and pipe is inside diameter and doesn't always have a uniform wall thickness even though it's teh same schedule, tubing is always really accurate depending on what specs.

 

Thanks for the info. That is probably what I will do.
