Celica Forums General Discussion Exterior TSRM and CEL

hey i just installed my tsrm exhaust, sounds great btw, but after a bit of driving i noticed my check engine light is on. is this normal? and how do i turn it off?

unplug the negative terminal on your battery
let the car sit for 20 minutes
reconnect the battery
start the car
no more cel


i think that resetting the ecu will make it go away.

anyone remember this? SIR Isaac posted it a while ago.
