jjones posted:I'm curious how you mate the OE exhaust with the big bore headers. An adapter or cobble up the exhaust to use a larger flange?
You could use an adapter that tapers from 2.5” to 2.25” or 2”. Stainless Headers, GP Headers, or Stainless Works either have what you need or would build it for you. I had GP headers build me a set of headers in 304 S/S with a 3” collector. They are a modified version of the Hall headers. I had a 3” exhaust roughed out. Sent the exhaust to GP Headers to make it that in 304 S/S. I had them taper the end of the exhaust down to 2.5” to fit Pantera Performance mufflers. They did a nice job.
