A couple questions about deleting

[Md Jeff]

I know google is my friend but figured I'd ask here as I've been reading posts and comments for 3 days or so and deleting looks like it's the way to go. My truck is a stock 2016 QC with 8k on it, it still has all the factory emissions installed.

1)Considering the MM3 and plan to keep the downpipe, is it ok to leave the existing O2 sensors in place and connected or do I need to remove the sensors and plug the bungs or just disconnect the connectors and seal them up?

2)I presently have a BD Plat GT installed with a TPS booster, I know that will have to be removed but I can read 1st and 2nd pyro with the BD, I take it the MM3 pyro senor will not be able to use my existing plug harness and a new wire will have to ran, correct?

3) If i order downpipe back exhaust with the pyro sensor with the bung come in the pipe?

Any tips and insight will be appreciated. Thx

If you are completely deleting you’ll need to install a 4” or 5” Flo Pro TBE exhaust system along with MM3 from Ray at DRD if your gonna run Emissions Intact Tuning then no need to remove any hard parts but you’ll need MM3 emissions intact tuning

This is where I need help; completely deleting? I plan to leave my CC in place but remove the DPF, def and whatever else is in the exhaust, I was planning on leaving the egr in place but disconnected/deleted by the MM3, is there any gain by removing the downpipe? I've read it will help keep the noise down and has no ill effect on performance or mileage, is this wrong?

I am running the 5” Flo Pro TBE just the first section of pipe connected directly to the turbo you can just go ahead and unplug the EGR and the Throttle Valve after you have the custom tunes from Ray at DRD on your MM3 you don’t have to remove EGR or Throttle Valve if you don’t want to you can do it later on down the line

Sure you got great performance with it, how did the sound inside the truck change? Asking because we tow 8hrs sometimes and I'm worried without the Cat in place the noise inside the truck would greatly increase.

It really isn’t very loud inside the cab of our trucks they are so well sound insulated not to bad you can talk inside cab to other people if that’s what your worried about bud

It isn’t obnoxious at all just sounds mean with a little grumble or growl

Exhaust volume can be managed by adding or using a muffler. Vibration can be significantly reduced by adding a flex pipe between the down pipe and the rest of your exhaust.
