for the header in 2011 5.3 chevy. how much gain should I expect? do I need to replace exhaust , muffler etc to see the gains? How much is the Y pipe needed? Will it still pass smog in CA? Thanks Jeff
Average dyno results after installing the Kooks 1-7/8 in. Long Tube Headers show gains of around 20hp from just the headers. With headers and an exhaust system combined, we have seen gains of around 30-35hp. A Y pipe is required for use of these headers.
