Good evening everyone,

I recently got a 2009 Challenger RT and am wanting to beef up the sound with some things listed in the title (Already have the LT Headers/Midpipes in mind). I am tracking that I will need O2 extensions, and was wondering if I needed any type of programming or something crazy like that done (MDS Disable?), or if I can just get these things bolted on and be good to go.:bigthumb:

Happily my Belanger tri-y headers and high flow cats didn't throw a code/CEL (as advertised), but it wasn't performing to its potential until I got a custom tune. So you may not need a tune but should plan on one regardless.
