read this thread again, theres 2 good links for hp etc. Search cat back exhausts or cat deletes too. Most folks use magnaflow. A cai is good for simple bolt on mod. TVT just closed so whatever you read about them is obsolute. I think eurocharged will tune ecus.
Again, search!!!! write down stuff you need further explanation on and PM Beaner, hes a wealth of HP knowledge and takes time to assist the new folks. Welcome to the beast forum going
