I just picked up a set of used headers for my '92 rs 305tbi but do not know what brand they are all they have is mr. gasaket stamped in them they have 2 1/2 collectors the problem is where do I find a y pipe to bolt up to them and what size y pipe should I use

 

flowtechs have 2.5" collectors. so it could be a set of flowtechs, or it could very well not be either. post a picture if possible.

flowtech does sell their y-pipe seperated if they do indeed turn out to be flowtechs.

 

Just to be sure are they shorties?

 

thanks for the quick replies yes they are shorties also they do not have provisions for a 02 sensor or air injection I was told they came off a '84 trans am they air injection is getting ditched and I will weld in a fitting for the O2

 

i was under the impression all the flowtechs came with an O2 bung welded to the collectors but not drilled through. thats how mine came, cause I didnt need the O2 sensor. you can probably buy an emissions legal set with the bung already drilled and tapped.
