Alternative to Walker downpipe?
Looking to do the EFI exhaust manifold swap on my 4.9L inline 6. The Walker 45166 Y pipe isn't available right now. Assuming I can't get a hold of one, what are the options?
TIA

I just used the stock exhaust that came with my manifolds. I straight piped it to a two into one muffler. Sounds really good.

You're right! Their part number is EXH 45166 and they are asking for a little more than $79 here in Arizona since it has to be shipped from a store back East that has one in stock. But yeah, Summit, JEGS, AutoZone, etc. can't get them but NAPA still has a bunch.
Thanks for the tip! I have one on the way.
By the way, I called Walker and was told that while the part is not discontinued, they are not likely to be shipping any for a few months at least.

The only way I could get a pipe was to get it with the cat also.
IIRC I got mine thru Rock Auto a few months back.
What ever pipe you get take a look inside to make sure the hole is open as some have been really small.
