Magnaflow 12226 SI/SO
 

So, thanks to all on here and def Darren, I chose this muffler to replace my stock unit. It worked perfectly. I paired it with a 35416 which is a 2.5 in 4" X 18" tip. It sounds really good. Loud when you're on it and basically disappears when driving or cruising. I have absolutely no drone in the cab which i love. I dont know if it is because of the placement of the tip or what but I took some advice on here and put the tip 2" OUTSIDE the bed for a no vibration affect. I love it.

Thanks again everyone and I will post video soon.

Awesome glad to hear you are happy with your set up.
