Ordered 4" dual MotoBlue exhaust from rpmoutlet.com. 14ga system pretty heavy stuff . system installed fairly well, only one pipe had to be cut to lenght before the muffler. I eneded up dropping the spare and back the truck up on ramps to wrestle with the over the axle pipes which exit out the corners. took about 4 hours total to remove old and install new and i didnt have help untill i got to the over the axle pipes. No drone at all barly any interior noise, can be quite loud if you are right behind the truck though!

 

Sweet! I just got through putting the MPRP 4" system on and the fit was top notch! Maybe took me an hour+ to install. How do you like your Jammers? Injectors are next for me.
