I have a set of headers that i got and were told they would fit on a 3rd gen camaro. They are long tubes. The only markings that i can see on them is a number 12 on the flange. From what i measured they are 1 1/2 primary and 2 7/8 collector. Any guesses? Also, what is the stock size pipe for the y-pipe? I have a 87 Z28 with a single cat. Its a 305 TPI. Hopin they would fit on my stocker for now.


Thanks,

 

just remembered that LTs wont fit stock y-pipe. Anybody know what kind?

 

nobody has a idea?

 

You didn't supply nearly enough info. How about a photo or something?

 

I dont have a photo. Otherwise i would be able to find them. I have looked at almost everything out there and none are exact. some are DAMN close like hedmens. Look kinda like hookers as well. Was hopin that the "12" that was stamped on the flange would help.
