2018 TD emissions delete

Hey guys, couldn't find a decent thread about this so I figured I would start one. I've got my 18 TD terrain in the shop getting tuned to shut off EGR, Adblue, and all other emissions related equipment. It is getting a straight pipe from the turbo to resonator. I will post an update and some pictures when I get the car back next week.

A little back story that led to this. My car has 25,000km on it. And in this time it has had 3 egr valve replacements and a DPF filter replacement. Leaving wife stranded twice. So it's time for that stuff to go.

If there's been a thread about a FULL delete please share the link!

Following this thread, I just purchased an 18 Terrain with the 1.6L TD like the idea of the fuel mileage but not sure about the DPF and emission systems. please let us know how your project goes. 51K miles runs great so far.... only time will tell

Emissions systems are the Achilles Heel of Diesel engines, they are at the stage that the 70s engines were before the advent of wide spread computerization. With only having 25k on the clock, i guess you are not going to be concerned about your 5 year powertrain warranty any more. I am surprised that you were able to find a shop that will do this for you.

You would be surprised at the amount of shops that will cover you deleted. As you mentioned, they know that emissions do more harm then good to the engine. And generally, if their techs tune ypur vehicle your good. Especially with no HP or TQ adds!
Update: car is tuned and deleted. Runs and drives. Custom exhaust has replaced from the turbo to the resonator as nobody makes an exhaust kit for this haha. They have some programming with the TCM to figure out and should have my car after the long weekend to post up some pics!!!

How’s it sound? Any louder, turbo noises?

I won't have it for another couple days. According to my tech, he said he had to look to make sure the exhaust shop actually did cut everything everything. He said it's not a huge noise increase whatsoever. I left the resonator in, in hopes it wouldn't be too obnoxious. My 15' duramax has that base covered already 🤣
I am really surprised you were able to find a shop willing to something that will cost them big time fines and worse. In the 70's shops were threatened with fines and if the mechanic was certified he could lose it for removing cats.

I'm thinking....because not in the US? Would be a huge deal here. Once upon a time in NJ they used to make sure you had all your emissions stuff in place during inspection. I had an inspector poking around under my hood one time many years ago. Now maybe not so much.

Like John said, with being in Canada things are not as strict. I'm sure eventually it will make its way up here. But for the time being, full send! Haha

I'm not aware of Canadian emissions standards or, more importantly, enforcement thereof being any less stringent than US. Vehicles sold in Canada have to meet Federal standards.

Back to the US, look at the trouble VW got into just for tweaking the DEF algorithm. A friend of mine bought a CC diesel, drove it for 3 years and VW had to buy it back from him for what he paid for it.

Shade tree mechanics can get away with a lot (at least w/o inspection/testing), but shops with with business licenses and certified techs are running real risks.

That's what I'm saying. We don't have smog checks. All you need is a muffler to pass a safety. Once a vehicles registered your good to go

They still look. Inspection station has a undercar camera to see if convertors are in place when they roll it up to the OBD plug in station. Also use a mirror on a stick to look if camera view looks out of place.
'95 and older (non OBD 2 are now emissions exempt)

UPDATE: got the car back, all is good and running! The exhaust shop did a great job. All said and done with tunes and exhaust I was around $1500. Took some time and tweaks as full emissions delete hasn't been done on one of these that I could find. Factory resonator remained in place. Sound increase is very minimal. Mostly just a turbo whistle you cnlan hear now. Smoke is very minimal. It seems I can only get it to puff by stomping on it from a dead idle (before the turbo has a chance to spool). I'll post some mpgs later after the wife goes on a road trip in a couple weeks

UPDATE: First road trip since full emissions delete. Car was loaded with bags and kids. I believe it works out to 50.4 mpg (imp). No issues, no CEL. Cars running awsome!

Just curious on how it has been working. I have an 18 TD terrain as well and I wanted to delete as well. Can you on me what shop you used? Thanks
