Sean,
I have to apologize. For some reason when I looked I didn't even see your y-pipe
However looking at the correct list now I don't see a catted version so I have to ask: am I missing this one too?

Well F me twice then call me in for dinner......
After all of the trouble Sean and my wife went through getting me a set of 1 3/4's delivered by Christmas, I just ordered a set of 1 7/8's. Might as well since I haven't installed the smaller ones yet. (Who knows WHEN all my stuff will go on, fixing up an old house with a kid 2 months away)
Sean can you PM me about a couple smaller doo-hickeys I might want to add on for my truck? Thanks.

If you live where they do visual exhaust inspections then you can't delete them.
If you live where they don't then you can, there's several threads on deleting them. You'll have to have the codes tuned out of the PCM as well as removing the hardware.

I have a question about the Air/EGR version. I will be buying a set in the next month but things don't match up. On the web site it says the primaries are 1.7 part # 25-1001, which I would assume is 1 7/8. On ebay is says 1 3/4 part # 25-1001. Can you tell me what the actual size for these headers are, and is the size the actual size of the whole pipe, not just the ends then go smaller. Please PM me so we don't have to clutter the board.

If I ordered these (1 7/8) next friday (June 13th) with a Y pipe when would I expect these to arrive to me?
also wondering about the graphite gasket vs gm gasket ^^

Our Air/EGR version has a 1.75 port with a 1.6-1.7 primary tube. Here is the link again to the 1 7/8" version. We are expecting them within approx 3 weeks:

We recommend the GM multi layer gaskets. The graphite gaskets aren't bad, but they are like any paper style gasket. They have the potential to blow out, and with the flex allows header bolts to loosen up. You wont have any of those problems with factory GM gaskets and stock bolts.
Thanks
