'15 Long tubes on an '18

[Screwdgie]

I'm sure this has probably been answered before, but would my 1-7/8" catted ARH long tubes from my '15 fit on an '18? If not, what modifications need to be done?

Long Tube Headers for the 15-17 will work on a 18. However, apparently the oxygen sensor harness on the passenger side for the 2018 is different from the 2015-2017 models. Since you have ARH Headers, may have to reach out to them to see if they changed anything with the hardware, and if they did, ask if you can purchase the necessary hardware.

The reason i know this, i basically reached out to everyone that manufacturer Long Tube Headers for the 2015-2017 to see if they work on the 2018s, and the common thing was the Passenger Side O2 Sensor, some companies were going to include additional parts or they were going to make specific 2018 headers

I ordered a set of O2 extenders from Amazon and one of the extenders was unusable because the connector was completely different. I ended up not using it, didn't need it on the driver's side.

First not all the 2015 headers fit on the 2018. For exemple BBK don't. Other are tight. They slightly change the A/C line on the 2018.

ARH long tube headers fit!!!

For the o2 you may find some slack on the o2 harness if not you can extend the wire of the o2 that's what I have done as they change the o2 connectors on the 2018.
