Help finding Y-pipe

Hi, I own a 90' 350 TPI formula and I'm looking to change my exhaust entirely, I found these headers I like, https://www.jegs.com/i/Flowtech/387/16102-1/10002/-1?gclid=CjwKCAjw5MOlBhBTEiwAAJ8e1skum5CAP0bOYQtMOYnPFaUmXoAiv4FdDGmg5utA-vdNbPGvFpiWuRoCQgQQAvD_BwE BUT I don't want to have the same Y-pipe/ the pipe included. I'm looking for a Y-pipe like the picture included but I cannot find any, any help or tips would be appreciated! NOTE the picture is just as a reference of the design I'm looking for, I know it's an ls conversion

Re: Help finding Y-pipe

The picture that you referenced is for an LS conversion.
The SBC y-pipe is completely different, like the stock design.

yeah sorry for the confusion, yeah it's just a picture I pulled off of Google, the headers in that picture are not the ones I want, but i put that picture as a reference as what kind of style I want

This is the hawk's budget one for LS swaps, about the closest without buying an entire exhaust. You could also try just searching for "ls swap y pipe" and see if something comes up.

Re: Help finding Y-pipe

I believe that this WAS the system that you wanted. Now discontinued.

Re: Help finding Y-pipe

Using shorty style headers you're not going to find y pipes like the one pictured in you example, they don't exist, if you're insistent on wanting your exhaust like what's pictured that's all custom fab work. Since most aftermarket exhaust companies headers are mostly all different you're more than likely gonna need the Flowtech y pipe to make sure that the collectors mate up, then get the LS swap y pipe. Cut off the Flowtech collectors and fabricate new exhaust pipe to mate up with the LS y pipe.
