3 bolt downpipe flance?

[05Monsterdmax]

Going to delete this piece of crap 2015. Tired of having multiple issues and only having 2500 miles on it. My issue is this truck isnt a vband connection at the downpipe exhaust connection like in prior years. Figured it swap downpipes but are they the same as previous years? I couldnt look and see with all the crap they have piled on these new motors, but did see it has some sensors on the upper curve of the downpipe. Does anyone have exhaust for a ccsb with a 3 bolt flange?

from what ive read you just have to get the new downpipe and clamp for the trucks with the flange.

Is the sensors bunged in the upper curve dpf or something else?

If it is like earlier lml's I believe you only have the 9th injector nozzle in the downpipe. There may be an egt probe too, I don't remember. Either way if you're deleting it you don't need to worry about them anyway. So any downpipe that fits the turbo will work.

Or cut the factory and the new piece and make 2 into one

Flowpros website says to use 11-14 exhaust kit with their 11-14 downpipe if you have a 3 bolt 15

I've never personally done the swap yet.

We've done several kinda like Riley does. We just cut the very end piece with the 3 bolt clamp off the stock exhaust & weld it to flo pro front pipe. No other way I know of.

I looked at cutting it today. May go that route and just use a blocker plate on the egr, then reroute the pcv

Friend of mine deleted his 15 1/2. Had to buy mbrp DP to avoid the 3 bolt flange. He said it bungs in the DP for sensors and what not.

Easiest is to get a 3" down pipe and exh system for earlier LML's. That's what we do at the shop.
