O2 sensor & exhaust Q?

[prodriver1]

my 98' leg GT has 2.5" header back exhaust to a WRX muffler, my question is what the best idea is for the O2 sensor. should I get a dummy sensor or what. there is no cat or anything just the muffler for now (2.5" glass pack coming soon because its too loud for me)

high flow cat, people on rs25 have shown it's only 1-2 hp difference if any, cuts down on noise, saves the environment lol, and *should* prevent any cel issues if you get a good ceramic one

I never got to try but some say using a spacer betwwen the o2 and the bung worked, I don't know for sure though. Are you still on MnSubaru?

Lol, imagine that, we're trying for another big meet in Fargo Saturday dragstrip during the day, meet/food/cruise drinks in the evening. Autox on Sunday.

I assume you're talking about the rear O2 sensor cause you definitely still need the front one. For the rear I've had success with the spacer technique.
