The Ultra Flo is supposedly among the highest flowing mufflers available for a given size.
I've used Dynomax Super Turbo mufflers in other applications (truck with true duals) and they were very quiet.

I have no personal experience with the Dynomax catback for 4th gen F-body, but the only real criticism I've seen of it is that it uses aluminized pipe, whereas the more popular catbacks use various grades of stainless.

The super turbo has an internal -S- design with fiberglass packing. The Ultraflow has a straight through design with the packing also. You can see right through the Ultraflow. I had the super turbos on my mustang. They were pretty quiet. I currently have the Ultraflow on my Z. It's very deep and screams at WOT. Click the 1st vid on my webpage to check it out.

If you mean #17406, the one with two tailpipes on the driver side, I have that one. Good fit, reasonably quiet when cruising, but the tailpipes were super ugly so I bought tips from Summit. Still it's a bargain with the $25 rebate.

The super turbo is my favorite muffler. The design gives the neatest, most unique sound in my opinion. Flows like a b/tch too. A little backpressure down low I think b/c I've never noticed any loss of low end.

I had a Super Turbo on my Caddy and it sounded great! Got lots of looks.

But, it droned pretty badly around cruising speed (1500-2000 RPM I'm guessing, no tach! LOL).
