I want to put a straight pipe exhaust on my Subey. Do i need to get the fuel/air mix adjusted so I don't overheat, or will I be ok? I'm just starting to put together extras on my car, any other tips and stuff let me know. Thanks

 

turbo back with straight pipe??

 

Im running cobb high flow cat downpipe to straight pipe. My CEL is on but the car runs fine and sounds like secks. !

 

Are you referring to your Forester? If so, I may be wrong, but straight pipe + NA car isn't that great for performance...
