Ok guys, my buddy Verbs posted this thread for an arguement we are having...
I agree 100 percent, the Flowmaster catback for F-bodies sucks, our arguement is about a C6 Corvette catback, which uses 2 mufflers, just like a mustang catback, its not the cross flow dog **** like the F-body one...
That means...
We are interested in Corvette dyno numbers, or guys that have/had true dual setups on F-bodies with Flowmasters..

I personally find it hard to believe that a true dual setup with flow 1 chambers would flow any worse than any other non-straight-through muffler.
I do, however, agree that a bullet or similar will outflow it. I think the flows sound a whole lot better though, and I will be going with the one chambers.

I have a dual setup on my car with the 1 chamber Flowmaster race mufflers - they flow great and make good power - a bit loud dumped before the axle though. We are gonna put the pipes out the back one of these days.
Above, I was refering to the F-body crossflow catback - they suck.

Maybe the single large ghey muffler for the F-Bod sucks, but true dual vs. true duals with the same exact mid pipe doesn't show much of a change. I've ran several catback sets on Mustangs of all power ranges and there were almost 0 difference at the track. I remember reading an old Muscle Mustangs and Fast Fords magazine a few years back where they dynoed EVERY single weld in muffler on a 400rwhp blown 5.0 ( Flowmaster, Borla, Magnaflow, MAC, etc. about 15 brands in total). The difference between the best and the worst muffler was only 5 rwhp or so. If you are running true duals, choose a muffler based on sound only.
Please, don't quote muffler vs. muffler numbers if anything else was changed at the time (inlet/outlet size, cats/no cats, mid-pipe design, headers, etc.) Keep it consistent.
