Since there is no classifieds section I'll post this here.

I'm looking for a set in good condition. Please email me if you have a set and are willing to sell.

Thanks,

Alex

 

I have a good set of 1 5/8" SLP Tri-Y's. I haven't considered selling them because I didn't know what they were worth. (sometimes just having the parts is worth more than what they are worth to someone else) They are 409 stainless and I bought them directly from GM. I have the accessories that go with them including the flange gaskets. What are they worth to you?

 

You've got mail

 

I have the tri-y setup and I have no idea what it's worth. I've posted before but I'd really just like to know exactly how many cars have these headers on them.
I wish there was more information about them from like an engine dyno compare. The only tri-y headers now are those Thorely long tube but they're hidious. Then again there are those flowtech 3-2-1 but it's still not 4-2-1
Anybody know what it cost from back in the day when they were still being made?

 

I've had my SLP Tri-Y's since 1989, before GM dealers started selling them as part of the of the SLP package. The retail price for the headers alone was $995.00 back then!
