The Invidia N1 is one of the best sounding, fitting and looking catbacks you can get for your GD WRX/STi. It's easy, remove old quiet exhaust, install Invidia N1, turn car on, profit. Just kidding, but it's really that easy.
Note: If you're using the factory downpipe, you will need to add a catback adapter as well!
