I just installed this system on my 2001 LS-1 6-speed (mag red convertible). If anyone wants to know more about it, let me know. I can hook you up with a good distributor to work with. Anyone that is reasonably mechanically inclined can install this system themselves as I did in just a few hours. It is specifically designed for the C-5 and is well engineered with replacement parts so that if you ever want to return the car to stock, you have your original pieces intact without any drilling, cutting or modifications. I highly recommend it. The car should now be running about 550 h.p. on a stock LS-1 with Corsa cat back exhaust. I'm now looking to bag my first Viper or some other car that some fool paid too much money for....
