Okay, how tough is this really? My dealer wants to sell me a PPP Stage 3 kit. Everything looks simple enough... except the uppipe. What has to come out to install? The kit requires the TMIC to come out as well as the down pipe and intermediate pipe. It would be less hassle for me to spend a day on it then try to arrange a visit to a shop to install. ECU change would be performed by dealer approved shop. Car is 05 WRX wagon.

Thanx, Mike

 

Remember to take both keys to the dealer for the ECU swap as it has to be "taught" to recognise them both.
