Has anyone been around one of these mufflers? I am thinking about getting a SI/DO one for my truck. I am just going lop the stock muffler off and install it there then run 2x 2.25" pipes out the back with 3.5" Magnaflow tips. There is a clip of a F-150 on youtube that sounds very good with this setup, I was just wondering what other peoples experinces are with them.

 

Here is the clip I mentioned, let me know what you think. I ordered tips and they should be here in about a week, then I will order the muffler.

I actually got one of the vortex exhaust kits shortly after i got my 04 5.4 and its a pretty good sounding kit. I was expecting it to be louder as my brother has it on his GMC and its alot louder. The fit wasnt 100% but it didnt take much to get things working good and im pretty happy with it. Right now im kinda curious if they have new y-pipes for the truck to get either high flow cats or ditch the cats all together.

 

The current plan is to just cut off the stock muffler and put the new muffler there and get a shop to bed the duals to come out the back.

I was stating I would like to do it that way instead of a kit, not sure what the three slashes mean.
