I did an uppipe install a few days ago (STI uppipe)......and there are no leak problems for sure. A shop did extensive tests to prove it. Whenever I get to really high rpms or when I get on the gas (expecially when launching it) the car makes a screeching noise which I can't figure out. I'm not loosing any power when this happens but the noise is so irritating I can't stand it. I asked a shop that has been doing work on many WRX's and they said this noise is really common on many WRX's that do an uppipe install. I did a search and a memeber with the name "BobbyD" seemed to be experiencing the same problem as me. I still don't know where the noise is coming from and how to explain it. If anyone has experienced or heard about this same screeching noise at high rpms after doing an uppipe install let me know where the sound is coming from and why.
Personally I think it's coming from the turbo spooling but the sound is too loud.
Thanks
