Any Dyno #'s On Kooks Lt Headers Has anyone dynoed there car after installing kooks lt headers and off road Y pipe? I am starting my install but their are no dyno shops anywhere close to where I live. Just wondering what to expect.
What year car? The 98-00 LS1's will get the most power gained after a LT ORY setup is installed due to those years having more restrictive exhaust manifolds compared to the 01 @ 02 cars. There is not much difference in the power different LT headers make so expect 20+ rwhp and 15+ rwtq over your manifolds. More than likely you will be running rich after install and won't get the maximum potential of your LT's without tweaking the Air Fuel Ratio. HTH
