Has anyone used a Dynomax Ultra Flo X Muffler?

I have an LT1 and a '01 camaro fuel tank, I want to run duel exhaust.

I thought of installing this instead of an x pipe , and use a couple of

these MagnaFlow 10416 on each side of the fuel tank because of limited space.

what do you think? have any suggestions? I'd like to have it quite but make some noise when the go peddle is smashed.

I haven't used the ultra-flo X muffler, but thanks for posting. I currently use a pair of old 40 series Flowmaster mufflers. They sound great, but they are heavy. So I am considering replacing the two flowmasters with a single ultra-flo X (somewhere along the tunnel) with mandrel bent tail pipes to the rear.

 

I think the Ultra-Flo X should provide sufficient sound attenuation without additional mufflers down stream (At least for my application: E mod autocrosser).
