Muffler help...

[BlackMetal]

A section of straight pipe the length of a typical muffler, rated at the same test pressure as a carb (10.5 inches of mercury), flows about 115 cfm per square inch. Given this flow rating, we will see about 560 cfm from a 2.5-inch pipe.

I wish you all luck getting 1133cfm out of your ultraflows .

I want to order the ultra flows from Jegs, but I don't want to get the wrong ones for the hooker catback system. Can somebody help me out before I order the wrong ones? Thank you,

I have the race magnum welded muffler, that's what jegs calls it anyway. Dynomax calls it ultraflow welded performance muffler. Same sh*t. the part # for jegs is
289-17219 Race Magnum Welded Muffler
In/Out: 2-1/2''
Body Length: 14''

$69.99

Thanks, good luck with your "chambered" mufflers
The bottom line is as long as you're happy with them, then more power to you.

Did anyone ever figure this out?

I did some research and all I could find out is some rate their CFM at 18", 20", and 25".

I am trying to compare the hooker maximum flows to the Dynomax ultra flows.

Hooker Maximum Flow Mufflers: HOK-21604HKR - summitracing.com

Dynomax Ultra Flo Mufflers: WLK-17272 - summitracing.com

just my guess, but since the Hooker is 18" and glass pack(straight through) style verses the Dynomax's extra inch and turbo(baffled) design that the Hooker's flow would be higher.
