Well for those who considered a cutout it did nothing for my blown grand Prix as far as performance. I tested it on the track and with an accelorometer. But as far as booty callin goes and scaring ricers it did the job well.

Also I use to open it up instead of honking to get peoples attention in a parking lot (idiots who stop for no reason and talk on their cell phones). It was fun too every time I saw a cop I would open it up and then close it right away. I would consider this over a droning exhaust though.
