They had an exhaust cutout to bypass the exhaust when at the track that you can open without taking any exhaust off. Keep in mind that this corvette was dynoed with all belts on with the stock GM water pump and had 4.10 gears and big heavy 19 inch wheels and tires and is a vette with IRS too as well as having a heavier clutch and flywheel in it. With the stock gears and reg Z06 wheels and tires and an EWP and belts off it probably could have put down 640 or more RWHP easily in true dyno queen mode but they tested it exactly like it really rolls on the street. I know they are getting ready to put a less restrictive cat back on it too. When I drove it I couldn't believe how quiet it was. I am sure they will have a video up soon though.

Thats pretty incredible power out of a 408. Is it mostly a track car? I ask because with 4.10 gears I can't imagine you'll be able to get traction without slicks. Congratulations to everyone involved.
