Edit: Supertrapps? Didn't know they bought out Jardine Performance Products in '12.
No, a different design than Super Trapp. I'll post a pic I found of the style I'm asking about later for those who aren't familiar with it.
Pic of long version cut-away showing "attenuation rings", and short version (available in both 3.5" and 3.0" ID) that I was wondering about using.

Don't know for sure, but I'd guess-timate the shorter case would only have 3 rings at most.

As shown in the cut-away image, from top to bottom (flow goes w/ the angle of the fins/rings, not against).

I think that is pretty cool. Never seen that. I would definitely say that is a AR device.
Ho well does it knock down noise?

Flowmaster makes no db reduction claims... says it's an option for tracks or classes that "need a muffler, but don't have db limits". Could just as well be an empty coffee can, except somebody decided to put those curved-back discs in there for whatever reason.

If I incorporate them into my street/strip car system, I'd have no expectations at all it would tone down the noise.

FWIW, here are pics of the 3.5"-to-3.0" adapters that feed into the 3.0" X-pipe...

I also saw on another thread where you mentioned using AR mufflers after the X-pipe. I suppose that could also be an option... ?

Yeah, go ahead and stick them in there right after the reducer.

When racing in a class that requires small headers to limit power, would anti reversion devises be of any benefit?

From what I've described, would you recommend that I stay with the 3.5"-to-3.0" reducer and use the 3" ID unit, or change to a straight 3.5" collector adapter w/ the 3.5" version and then drop it down to 3" after that?

BTW, thanks for your input on this. :notworthy:

Get a smaller collector and stay at 3.0"

We tested a lot of mufflers - The Outlaws made the most power.

or you can get it a hell of a lot cheaper, when it's already been through the horse.
