You can pass emission if you keep your set up simple. Don't try to shoot for some all out race type of deal. My gas is about the same and far as passing emission yes i can pass. I drive my car every single day. So yeah You can daily drive i only get on it hard when i am at hangouts and playing around. GET A PROFESSIONAL OR SHOP SO YOU WON'T HAVE ANY PROBLEMS. That is where alot of people mess up do it right the first time don't get cheap parts
