So I am a new evo owner, but not new Turbo car owner. I'm considering the concept g exhaust, does anyone know if the test pipe (where cat would be), have an o2 bung? I know about the cell fix But if there is no bung then I'm definitely gonna have a cel at least until the ecu gets flashed. Also what's the best price to get a turboback?

If you buy a different test pipe you would have to get a bung installed or when you order it you can tell them to add it..The cel fix goes in the mid pipe they usually have a bung for the cel fix to be installed..As far as a turbo it depends on what your looking for do you want it loud,light,looks,and make the most power???
