Well.. nothing yet.. I just received the exhaust and i am still waiting on the intake. Good thing i guess as I am taking the Jeep for a Dyno run next Friday (04/18/2014) with everything bone stock with about 7k miles on it. Then i am going to install the intake and exhaust, run the rig for about a month and re-dyno it to see the gains.
Now, my question is this... Dodge is releasing the "scat" edition 5.7L Charger/Challenger with a MOPAR ECM flash.
"As we detailed in our original post, three different Scat Packs will be available that will allow customers to upgrade their cars without voiding the warranties. Starting with the $2,195 Stage 1 kit, owners will net an extra 18 horsepower and 18 pound-feet of torque thanks to a Mopar-branded cold-air intake, exhaust and ECU ref lash. Stage 1 is also the only package that could be installed outside of a Chrysler-authorized service center without voiding the warranty (a mechanically competent owner could even do it at home, we're told by Dodge)."
