this chip is a logical step to go along with exhaust/filter upgrade to make your engine run better. port polishing- this is a grinding and polishing process for the intake manifold, to improve air flow and engine response. horsepower increase is small, but port polishing compliments naturally aspirated engines very well.

porting the exhaust manifold on a car is a great way to optimize the performance of the engine. when most manifolds are manufactured, they are not optimized for performance, since the amount of time it would take to do this would not be cost effective. however, tuners and engine builders have been porting exhaust and
in this video i show you a real simple way to achieve a nice port and polish on a exhaust manifold without the hard man hours. the benefits of porting your turbo exhaust manifold are: allowing
~~~~~ port polish ~~~~~ the game says: "smoothes the internal surfaces of the inlet and exhaust ports, allowing air to pass through with less resistance and inproving engine response. although the increase in power is only slight, this is considered essential for tuning natarally aspirated engines."
i was surprised when i checked my header pipe that honda would do such a terrible job of making a pipe. never seen anything that compares,old british,spanish,german bikes,no one makes as bad a pipe as honda on the 250 and 400's.i would guess it restricts 1/3 of the volume of pipe header,you have to see it to believe it.
katana header flow & grinding page: this page started as a small how-to by trinc (tim) and has been modified by the cyberpoet to show more information and images. enjoy! the sloppy weld problem. stock katana (gsxf - gsx600f, gsx750f, etc) headers are mig welded on the inside of the header port of the exhaust header.
