I've finally decided to get a DPF delete kit! :woot: Should i get 4" or 5"? I plan on getting the Edge J/A too. The 4" system from PDI is $350 cheaper so that is tempting. But almost everybody is getting 5" and they all say its sounds awesome. What u guys think? Also, is the PDI fooler box code free yet?

i did the 4" and really wish i had gone with the 5". To the point that i am thinking of buying a 5" system, welding in the bungs and using my fooler box.

I only droped the one side of the cross member and the down pipe came out but it will NOT without taking down that side.

I have the 5" TBE to dual 4" and love the sound. It only came with a muffler so it's not too loud, but it's got a good growl to it.
