Re: What do you think about this package? (NYtoCA)
Sorry, but there is no way an exhaust and headers is going to add 100 RWHP. Most stock LS1's dyno around 300 RWHP and to make a claim like that is rediculous. I could see it possibly with a cam swap and better flowing heads, but not without.

Re: What do you think about this package? (tscales)
Yep,
I believe it. Look at it this way, they start with an 02 Z06 which is already 365 to the wheels say, then they have many mods such as the pulley, intake, exhaust, etc...iI think they may get lucky and get 400 once. Then boom, there is their claim!
