Here is a video of my 9th gen si (sedan) with the Greddy supreme SP exhaust. Also paired with a RV6 catted downpipe. Not to many videos with this cat-back other than coupes so I decided to make some exhaust clips with the sedan. Cold start, warm start, revs to 1500, 2500, 3500 and 5000 with limiter. Hope you enjoy. I love the sound.
