Does anyone remember the tri Y headers SLP made in the mid '90s? They were sold through GM Performance Parts and were featured on a few magazine project cars: Car Craft's black MCSS with the SLP T shaped EFT manifold; and other's featuring a Firebird going 12's that was 49 state legal over a decade ago using SLP parts.

I guess SLP doesn't make the tri Y headers anymore? Just looking at the tri Y headers, they look like they give more clearance than the current 4 into one headers that they make.

 

I remember them. I was hoping to buy a set when I started my '87 IROC resto, but found they aren't made any longer. I also found out they weren't made in 1-3/4".
