Hello - I just purchased my 1st. WRX - 2009 Premium with SPT Catback Exhaust and I'm hoping this forum group will accept me and help with a few questions:
Does the Catback Exhaust increase horsepower?
Will adding a SPT Cold Air Intake increase horsepower?
When should I do my 1st. oil change?
When can I drive the car hard? Should I adhere to the 1,000 mile breakin period?
Will adding a hood scope grill protect negatively affect the turbo intake?
I really appreciate any responses and other advise.
