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.

Welcome to the club,.

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?
NO

Will adding a SPT Cold Air Intake increase horsepower?
NO <Somewhat debatable but the short answer is no.>

When should I do my 1st. oil change?
Debatable but somewhere between 1000-3000 is generally accepted.

When can I drive the car hard?
Debatable As it depends on how you adhere to the break in.

Should I adhere to the 1,000 mile breakin period?
Debatable but I would.

Will adding a hood scope grill protect negatively affect the turbo intake?
Yes it will negatively affect the IC but how much is debatable. IMHO they look far far worse then a minor dent on the IC fins.

I really appreciate any responses and other advise.
