I am in the process of getting some SLP 1 3/4 " Headers for cheap. They however are not coming with the Y pipe cause the guy had them welded to the exhaust and can't get it to anywhere to have it removed. (He's Mechanically declined). I need to know who makes a Y pipe that will roughly bolt up to the SLP headers. I don't know if SLP sells just the Y or not. I've read that their Ys are crap but nowhere can I find whats being done about it. Any help is good. I've searched good bit for this answer, but I'm sure it's somewhere.

 

I was in the same situation awhile back, i couldnt find a Y pipe for the slp headers so i went with hedman long tubes. After more searching i finally found one at yearone.com hope this helps, from what i heard it is a decent Y pipe but a little pricey.
