Hi!

I have a JDM FD3S R1 (1993), and I am going to change the exhaust system.
I have bought Blitz Nür-Spec R catback, 3" downpipe, and I have also a hi-flow cat which is welded to 3" midpipe.

I live in Finland so i don`t need airpump, and it`s already decommissioned, but my i don`t know what i have to do with the exhaust temp sensor? If I just take it off will it turn on the heat warning light?

Thanks for your help and patience
