Over a month, and no replies? Did you find one yet?

MAC Performance in CA used to offer a replacement Y-pipe, but MAC closed up shop during the pandemic. A web search might turn up some inventory somewhere, but not likely.

Jegs used to offer one, I thought, but I don't see one on its site anymore.

So I think the only one still available is from Magnaflow. Here it is from Hawk's and Summit.

Summit also lists the Walker Y-pipe, but says its special order. If it's discontinued, then I guess Summit will find out the next time someone tries to order it.

I tried to get that Magnaflow one a couple months ago. According to the supplier I used Magnaflow has officially discontinued it and they couldn't get their hands on one.

 

Since Hawk's probably has products like this shipped directly from the manufacturer, then they probably don't have/can't get them anymore. Might be worth a try though.

But that Summit link shows "only 4 left in stock--order soon" with a ship date of "today." If really in stock, then those might be the last in existence. Interested parties should probably jump on them soon.

 

100% agree. If I weren't located in Canada I would have gotten one from Summit, but at the time when I was looking shipping was through the roof. I haven't checked recently though it might be worth another look while they still have some left.
