I have a 2002 WRX with a UTEC and an up-pipe. I am trading the car in for a 2005 WRX. I am not taking the up-pipe off and I was wondering if anyone out there has just a UTEC installed and not an up-pipe. The only reason I got the up-pipe is because I was told that I should put an aftermarket up-pipe on because of the increased exhaust temps. I had it proffesionally installed by Godspeed (Detroit), and I am very happy with the results. My question to you is, does anyone have just the UTEC installed without an aftermarket up-pipe? I want to just install the UTEC into my new WRX and just use the same map. I know I may have to tweek the boost, but other than that, should I be worried. I don't want to have to spend another grand for an up-pipe and retuning. Anyone got an opinion.
