Do you have the NOS install kit for the tri-Ys ?
Has the Y pipes been sand/bead blasted???

Re: SLP 1 5/8 Tri-Y Headers, New Old Stock
ok, before i get a hundred pms, i just want to clarify what is for sale here. these are original, brand new old stock SLP Tri-Y ceramic coated headers for dual cat f-bodies and vettes. they were original equipment on select gm performance cars. gm contracted SLP for these back over twenty years ago. as far as i know this may be one of the last new sets in existence. this is a collectors item. i would prefer to sell these to someone restoring, say, a '91 firehawk to original condition, or perhaps a C4 showcar or something like that. i should be asking well over $1000 for these but i'm not. i'm only looking to get what ive got into them which is $700+shipping. i have no idea what these are actually worth because frankly, this item doesn't exist anymore and i seriously doubt anyone will ever see them new again. if there are any serious collectors/restorers out there who are interested, feel free to contact me.
