    first of all remove cng
    install a long ram air intake which sucks in more air then get headers made form a proper silencer guy get a 2.5 inch downpipe with a branded exhaust and install iridium plugs with good quality plug wires. All these mods come in the stage one category in N/A modification and will add approximately 50hp to your engine with wich u will be able to beat 2010 civic prosmatic

    This is not NFS - where you can add 50hp to a car by such parts. Specially on a car whose original HP is about 130ish, - you adding 50 means that you are adding 38% of the original HP - WOW OMG, I think you need to get a job at Honda, they obviously dont know how to build engines.

    btw - this car comes with extractor headers equipped from the factory, they are hidden under the exhaust heat shield - it also comes with a cold air intake system with a huge silencer in between. Whatever you try to modify - usually downgrades the power you want.

    If you want real power gains you need to look into deeper stuff, like getting a wilder cam and rewriting the ECU to that cam profile. For headers, take a look between the holes of the exhaust shield, you will see that your engine originally has extractor headers installed.

    Gain will be 50HP
    Even 5HP gain is difficult to get and you're saying 50.

    ^^ That is used to reduce inertia effect of an engine. It also introduces roughness as your engine is a 4 cyl.
