So I normally autocross my S2000, but I've always had the itch to see what the accord is capable of. Check out the videos, I have some additional information/tips below the vids. The car has an electronic exhaust cutout so this is how I was able to switch setups for each video. Let me know if you guys have questions. Enjoy!! Open Downpipe-275 WHP https://www.youtube.com/watch?v=RlY8ZPDaeDw Stock exhaust - 215 WHP https://www.youtube.com/watch?v=rfDnTOKDY1M So these runs were with the front Anti-roll bar(ARB) disconnected, I would highly suggest not doing this. It does make the car really easy to toss into a corner and it made it rotate a million times better. However, for multiple tight corners it makes the car way too slow to transition and quite sloppy. Also, the open down pipe made it much harder to steer the car with the throttle. It made the car seem very laggy in transitions. This in combination with no front ARB was unpleasant. Therefore I was 2 seconds faster with the exhaust cutout closed and running through the stock, yes I said stock, exhaust.
