im about to order these headers for my car...there the slp ones and I was wondering if these came with a y pipe...http://www.slponline.com/view_produc...RTNUMBER=30017

Nope, unfortunately most of the headers made for us dual cat guys don't come with a y-pipe. The only one I know that does is MAC. Otherwise you can get the SLP headers and purchase a y-pipe made by Random Technology, but that's $550 just for the y-pipe.

 

what headers do you suggest then? I have a flowmaster cat back right now. Can I put the single cat headers on my car and just run no cats but still use my cat back?

 

If you go with single cat headers, you'll need an s-pipe or custom pipe to connect the y-pipe/offroad pipe/cat (depending which route you go) to the intermediate pipe. You're also going to need to have your EGR, A.I.R., and rear O2 sensors programmed out because you won't be able to took them up with the single cat headers.

 

I installed SLP 94 style singles and you can hook up your EGR and AIR if you want to. You just need an extension for the EGR tube, the driver side AIR requires some modification with a different shape hose to extend it and the passenger side AIR hooked up without any modification. All the pieces needed came with SLP's kit for 94 style headers:

The only thing I didn't like about the kit was their header gaskets, I went with Felpro #1406's instead.

And of course after a few months I removed the AIR and EGR and had them programmed out anyway
