Pi3yeargrad did this on his truck. He's since traded it and bought an Armada, but if you pm him, he may be able to relate his experience with the cutout. From what I recall, it was unbelieveably loud and raucous, which is pretty much what it's good for. It adds a bit of HP & grunt since the exhaust isn't baffled by the exhaust, but if you leave it open on the street, you will certainly attract some VERY unwanted attention..... and possibly a ticket.
