This might be a dumb question but I'm very new to owning a 2009 subaru Impreza WRX. The car came with perrin headers and perrin intake. It used to have the exhaust and a tune as well but the dealership took them off in order to sell it to me. I am wondering if my car is going to run into issues having the aftermarket headers and intake but no tune to support them or exhaust. Please let me know.
