After I port and polished the motor I replaced the intake cover with a rain sock and some extra foam filter then replaced my "lawn mower" exhaust with a header pipe. RESULT: noticeable performance improvement and WAAYY more badass sounding. I also want to give a shout out to my ROCK BROS. pedals. These are awesome

Getting an engine to breathe good is what just about every performance part others than a piston does.
