DP-back exhaust ideas :
2x 2.5 or 2.75 inch pipes
The front section (where it mates to the down pipes) would be a detachable 1.5 foot section.
In this section, you would have either an HFC, or a 'test pipe'.
You could sell the same exhaust, and just pair the proper front section depending on whether or not the user wants cats.
Also, then the user would be able to swap cats with a test pipe at will for inspection, etc.
As far as materials go, I'm agnostic so long as it doesn't rust.
I prefer single tips with a 'y' attachment tip for people who want twins.
(I like real tips, 1 per pipe... it's just a personal thing)
Technically, you could have the mufflers themselves be bolted on for people who want to use another test-pipe to replace the mufflers.

+1, sounds like a good way to go. I would love an easy and fast way to take on and off my cats.
