I have an 02 Subaru wrx. Not sti .. Anyways I was wondering about the TBE and removing my catted uppipe if there is any relation.
If I were to set up a TBE is that my downpipe or up/dp or neither? I'm really new to the car world but have at least 5+ hours in the past 2 days researching my new beauty. Any tips it suggestions will be awesome.
