i got a weird story for you, i was installing my 3" DP the other day at work (honda dealership AKA the dark side) and i went home and car ran fine after i put everything back, rather i thought i hooked up everything. i forgot to hook up the 4 wire connector for the O2 sensor, funny thing is, the car ran fine, my CEL did come on, but it always does after a little driving do to the speedo cable not making a connection with the back of the stock gauge cluster. all and all i don't think i did any damage but i wonder if everything ran fine because im running a US91T motor and a 91-92 JDM ecu?
