I was researching and couldn't find a thread comparing the super turbo and ultra flow mufflers. I have the super turbo's which are a little on the loud side, if the ultra flow's are quieter will it be a big difference? Am I better off sticking with the super turbo's?
Which Dynomax muffler is quieter?

Bryan beat me to it. The ultra flows should be louder since they are a straight thru design. The super turbos are not. The TR's like the ultra flows better. I'm changing my Dynomax race magnums(getting rusty) to stainless welded magnaflows. Pretty much the same muff. Nice rumble..no drone.

I totally forgot that I have a good size exhaust leak from one of my mufflers, maybe that's what causing it to sound a little loud?

Sorry for getting this thread a little side tracked, I know this thread is about Dynomax mufflers, but because ATR haven't been around for many years, wanted to show what the ATR pit bulls look like to those who have never seen em before.
If you can find some used ATR Pit Bull turbo mufflers, grab em! These were offered in both aluminized steel & stainless steel. Of course, stainless are preferred as they will outlast the aluminized ones.
Here's some pictures of an old set I used to have until I upgraded to a pair of NOS (still in the box) stainless ATR pit bulls that I stumbled across. They don't appear often, but do become available once & awhile. Just gotta keep your eyes peeled.
You can see they are a "straight thru" design, which offer optimal performance on a turbo car as they offer little to no restrictions (but do drone a little at a certain rpm / frequency).

Depends..... On how you want to control your fueling, and what system you have to do it with. I can't speak for how the FAST systems work, but as an example: You can leave the narrowband O2 in place and use it to to control fueling under less than WOT conditions. As I do. The narrowband O2 is FAR FAR better at maintaining a tight stoiceomentric a/f ratio of 14.7:1 than any wideband could hope to be!!!
If at some point you decide to use either the Translator GENII, or Translator Pro (speed density), or SD2/Powerlogger (speed density), the narrowband can be retained to control a/f ratio at other than WOT coditions.
I run the SD2 system, and the Wideband is in control at Idle and WOT, while the Narrowband is in control at cruise condtions. This yields MUCH better fuel mileage at various cruise conditions!!!
I did the same thing when I was running the Translator Pro.
This is ideal for a part time racer, daily driver.
And of course if the car is primarilly a racer, then good fuel mileage isn't a concern and the Narrowband is of no real use.
