Default Flow numbers for 1 chamber Flowmaster?

Everyone says how much better the 1 chamber Flowmasters flow over the 2-3 chamber flowmasters, but I'd like to see some numbers. Does anyone have any flow numbers of say a 3" pipe versus a 3" 1 Chamber Flowmaster?

I see all these Flowmasters suck postes and flow numbers for the 2 and 3 chambers, but I have the one chamber race muffs. I dont care if I lose a couple HP, the sound it damn worth it!!!!!!!!

I care about the hp loss if it's 5rwhp since almost any true dual setup will sound better than the single I-pipe once you have headers and no cats. The only reason I'm still considering the 1 Chamber flowmasters is because there really is no room under the car for big mufflers. If I can get the Hooker Maxflow mufflers to fit, I'd rather have them since they flow better and aren't as loud at low speeds, yet louder at wot.

1 Chamber Flows sound the best of any muffler I have heard on the LS1, I would easily sacrifice 5 rwhp for them over bullets. They arent obnoxiously loud, and I gained as much hp through them as I would have through any catback~15+rwhp.

Are there any cut-away pics of this muffler? You can pretty much look at a pic of a muffler (inside) and tell if it's gonna flow well....

I have yet to hear the 1-chamber FMs. I'm sure I'll love it though, FM has always sounded good....

5rwhp can be made up with good reaction time and hooking up slightly better than the next guy that has that 5 rwhp on you. or, just spray it and who is really gonna give a **** street sound...you seriously cannot beat a flowmaster muffler backed up with a set of long tubes and off road mid pipe. however the hooker mufflers sound really sick at WOT. perfect for a sleeper car.

That's a 2 chamber for sure. A 1 chamber only has the deflector plates and that's it, no other horizontal metal plates IIRC.

That is a Delta Force 40-Series 2 chamber. The Delta Force 10 Series mufflers have only one V-shaped delta in the front chamber. Basically, the 10-Series race muffler looks like the one pictured only with one V-shaped delta; and without the rear chamber.

It appears you do not have a pic of a Race Muffler. I think you have a Delta FLOW street muffler pictured there.
This is a 30-Series Delta Force Race Muffler, note the one V-shaped Delta:

The 10 Series would look like this inside; only shorter with a singel chamber.
