I've been reading and researching. I also went into the archives and talked to the less than apt Jegs "tech" so here it goes. How do these headers come? There should be no Y-pipe since there are 2 pipes going to 2 cats, right? Are there 2(shorty)header pieces and 2 pipes? Are there just 2 header pieces that wind their way to the 2 cats? I'm confused. Please, if someone has DUAL CAT 305TPI, LMK how these boogers appear, un-installed?
Many thanks in advance.

Oh yeah. I'd like the part number if anyone can provide it for me.Dual cats. No y-pipe(I guess?)(no,I'm sure!)
Many thanks.

 

I have a dual cat on my 91' 5.7L,it comes with two small pipes that weld to your stock y-pipe. it doesn't go from the header to the cats. I was looking for the longest time to find a company that comes with a complete y-pipe assembly...no luck

 

I'm pretty sure the SLP's come with pipes to the cats, but no y after the cats though, you serious the TES don't? that seems funny to me.

I mean there should be no y-pipe if you have dual cats.The Y can only happen after the cats.So like I said there should be two headers and two pipes that lead to each of the cats.Am I right?

 

ya, thats the way I figured they would be
