Down Pipe Install have two questions

GEOS07335i · 03-16-2018, 10:58 PM

So I'm installing my ARM DP's and have two questions. There is a bracket that's attached to the bell-housing with two 12mm bolts one to each cat. Do I remove this bracket when installing my new down pipes?

Question 2. How the heck do you disconnect the post cat O2 sensor connectors. I dont want to break them and cant figure out how to disconnect them.

You may have already done it, but...

1) Yes
2) This video helped me a lot. Watch it from 2:30 and you'll see:

I removed the bracket and left the O2 connectors attached. I just removed the 02 sensors instead. So far I'm really liking the sound / fitment of the ARM DP's. Glad It's all said and done.
