I know the LSX guys like to shorten thier mod list buy saying things like "cam only", which is stupid, but moving on. On this 12.9 run, was it actually just with a cat back? Street tires? Stock suspension? If so, you've got one HELL of a driver mod. I used to be an LS1 guy, so this isn't meant to be taken as an insult. I've just seen ls1/ls2 goats at the track, and it seems to take more then a catback to get them into the twelves.
