I want to put a dumped Super 44 on my '07 5.4L.

I would like a SI/DO with something like the flowmaster Scavenger tips on the outlets.


Which Super 44 should I use?

The smallest size Flowmaster Scavenger tips I can find are 3" and I am thinking that those are a little to big. Any suggestions?

 

I have a SIDO dumped 40 series on my 5.4, but I honestly don't think there is really much point to have a dual out muffler if you are just going to dump it anyway. It's really so you can have dual pipes. I eventually want to just get rid of it and do true duals and not have it dumped anymore because I dont like how its sooo close to my drive shaft/rear diff. I don't know if its good for it....

but anyway if you want to do that I would probably just go with a 3" SISO super 44 and do a 3" or 4" dumped tip. That would probably sound pretty nice.

 

The reasoning behind the Dual outlet is that eventually I want to put pipes on but I am not sure at this time exactly what I want. So I guess it is just a want right now and not a necessity.

 

3" inlet 2.5" dual outlet muffler, with the inlet being centered.
