I’m have mine deleted andI know you can get the resonator back for exhaust and CAI and tune, but that is all she wrote. I've been trying to get my resonator removed, but no one wants to touch it. THat, and the size of our exhaust makes it hard too. Not sure what size it is, but it is 3.5 or 4". No clue though.
Anyone have the resonator and muffler deleted??
I've done the same, both the S&B CAI & DPF-back 4" exhaust (I had to put in a mini glasspack muffler to be legal in Pennsylvania. Apparently the turbo, SCR, and DPF aren't "muffler" enough). And I agree that I don't know if it gained anything but noise, though at least it gained good noise- lots more turbo whistle and more rumble from the exhaust at idle and in regen. Sounds more like a diesel truck. Definitely worth it for that alone.I’ve been running the 4” dpf-back Magnaflow on my rig with the S&B intake for about 15,000 miles. Sounds great, and much tougher when in regen. Lots of whistle, but not like the first 6.0L.
