I am getting rid of the duals dumped and doing duals over the axle. Which Magnaflow mufflers is everyone using for the duals? I am thinking the Magnaflow's that are stainless steel one that are 4 X 9 and 14 inches long . Everyone just posts 4 X 9 and magnaflow has a bunch that are that size. Please do not bash my thread. I have had Borla XR-1's and know they sound good.

I got stainless bullets from them, forget how long they are. They sound pretty damn good though.

Replied to your PM.

BTW, if you're running TD's over the axle, bullets should be fine. Mufflers + Over The Axle TD's may be too quiet.

Good luck!

The Magnaflow PN 11366 is what I'll be using on my over the axle duals in a couple of months. This muffler has a body length of 11" instead of the other Magnaflows which are usually 14", which will save me some space. The tradeoff is that it has offset/center ports on it, but I think I can work with this for the extra 3" I save in length. It is also not available in stainless.

To answer your question, I believe that most people who talk about 4x9 Magnaflows are referring to the 14" body length ones with center/center ports.

I used the aluminized- offset Ovals on my old setup. Offset In/ Center Out. I believe they were reversible.

I'm running a set of center in/out 3" inlet stainless mufflers from Magnaflow now, and I made 738rwhp thru them. Ask Tom@ls1speed.com for the part number.
