After looking at this thread:

I thought for my set-up I can't do away with the cat. So why not try to add a second muffler(small diameter round obviously) to the catback. Now I don't know how to fabricate so this might not be possible, but if one can add say a small Burns or magnaflow round muffler next to the driveshaft that should work right? Fabricators please chime in. Or better yet if you have had a similar set up made, do it work on quieting down the exhaust.

 

It can be done; I've done it-- I have two mufflers between the cat and axle-back. The mufflers need to be pretty small and the one I have right after the cat needed to be angled down a bit to clear the driveshaft.

 

Did it work on quieting down the exhaust note? What mufflers did you use?

 

Br will build you an exhaust with 2 mufflers. I was looking at it for a while but ended up going stm

 

It definitely did but it'll be hard to compare to other systems. I did a custom aluminum cat-back with a v-banded axle-back-- two mufflers between the cat and axle-back, then a third for the axle-back. This was without a cat. Since I did aluminum, I went with two aluminum Vibrant Race Mufflers, part no 12900.
