I have a 1999 Trans Am. I currently have LS6 Heads and Cam in my room. I am also planning on ordering a FAST 78MM Intake Manifold and Throttle body. As well as some headers. I already have a CORSA exhaust on the car as well. I was wondering what kind of gains I should see from this. As well if I will need any accessories to install all of this, or if they will just bolt on?
Thanks
