I have a set of JetHot (Hooker) LTs on my LT1 with a coated ORY
I need a set of cats or a catted Y to reduce emmisions, it's a DD and I can't
have those fumes being sucked into the cabin while I sit in traffic.

I see them for LS1s, but none for LT1s.
Any idea what I would have to do to the LS1 version to make it fit?

Alternatively, I guess I can have one fabbed up.
I saw that magnaflow has these 4" round ''Spun-Cat''s available.

I wonder how well they would work?

Magnaflow's website has about 30 to choose from.

Order them from ead performance. 179 for a pair shipped. They are the magnaflow metallic spun cats. Quick delivery for me.

EAD will get you a good price on them, give them a shout. ---->

They are "universal cats", which means you just weld them into your y-pipe and they work. Those cats are very nice and shouldn't rob you of much HP at all, and none untill you're making in upwards of 400rwhp.

A cheaper alternative to the metallic spun cats are the Magnaflow ceramic core cats. They will run about $50 each, maybe a little more. Talk to Tim @ EAD Performance. They don't diminish very much if at all any hp.

Will either ceramic or metal affect the ability to pass a smog visual inspection or emissions test?

They shouldn't because they utilize a similar catalyst architecture, smog should be about the same, visual should be good to go once they see you have cats on there.
