George, there are short MagnaFlow mufflers that come in 2.5" and 3" center inlet with 2.5" dual outlets....the body of the muffler is 14" long, 5" thick and 8" wide with an oval shape. $85 per, Magnaflow part # 12198, unpolished stainless steel. They also have a polished version.

This is the one I was looking at...$60
PART #:13288
DESCRIPTION:
Inlet/Outlet Size: 3in./2.5in.
Body Shape: 4in.x9in. Oval
Core Size: Single 3in./Dual 2.5in.
Body Length: 14in.

The one above is just wider and flatter than the first one.

I think I have the Hall Big Bores, my collector may have to be modified from a 2.5" crimped down neck near the collector end to a 3" so the there is no bottle neck. I should be able to run 3" from the header collector to the 3" MagnaFlow muffler inlet.

There are many other mufflers available from Magnaflow...you just have to go through the site one by one and find what you want.
