i also gutted my cat and drilled little holes in the baffles , after that i threw it in the garbage and had to spend money to get the parts again , nothing was gained and it sounded crappy , and it ran crappy with gutted cat too.
i imagine your air box mod probably added more whistle while it destroyed the bikes proper air intake requirement .
if you can not mod the bike with high end parts , properly, dont think by punching holes and cutting things will gain anything .
everyone would be doing it if it was good, you will lose performance .my stock fz6 will smoke any of your ghetto modded fz6's any day
im sorry but you have been told wrong, and really dont understand how a engine works. first theres is 0 difference between a decat pipe and a gutted cat, 0. is there a big gain from doing that alone...no. drilling holes in the exhaust wont do anything but change the sound of the bike some people like it and some dont, like you. i never drilled mine but i made my own exhaust, why dont everyone make there own exhaust...becasue they cant, and the few that could have done so and do so on a kickarse level. the air box mod....really, half the forum members on here has it becasue it works and its free, dont beleive me look up airbox mod dyno runs. it works simple try running a marathon breathing through a snorkle and see how fast you can go, for the bike its the same thing, the engine is really just a air pump the faster you can get air in and out the better it will run, and wether you beleive it or not my bike is moving some air on "ghetto mods" and havent met a fz6 yet who can keep up in a straight, and theres some guys on here who can attest to that. so in a long story its better to be thought of as a idiot then to open your mouth and prove it....read up and learn up and if your ever in the south ill give you a nice view of my "ghetto" exhaust till you can no longer see it only hear it......
