Exhaust Cutout/Bypass

Anybody have an exhaust cutout similar to this (http://cgi.ebay.com/ebaymotors/ws/ebayISAPI.dll?ViewItem&item=1831557912&r=0&t=0) on their civic. Are there noticable gains? Are there any drawbacks other than noise and pollution?

never seen anything like that before...where exactly is it installed at, right after the dp/before the cat, or after the cat??

i have no clue...
i'm assuming its before the cat for max power gains.

it should actully be installed after the cat, and its essentially having two exhuasts, a regular back to the muffler and tip, and switch the plate inside and its like dumping off the headers, very loud for track use only. ive heard it gives good power increase if you have some mods done to your car, but would prolly hurt your perferomance on a regular car.
