mate my mod made it really loud. the baffle removal would have done most of the damage there. removing the cats wasnt easy but it did get the bike flowing better. I also removed the AIS (most just block it off), and the snorkel from the air box. I did notice a difference in power, it seemed snappier, and didnt stall after the mod.

I did it in asia so there was no problem with emission standards there... dont know about here in oz though... later i fitted a new baffle to the bike that worked sweet, made it quieter, but deeper sounding with the same performance. ill see if I can dig up he pics of that final mod.

just running them straight thru like that did make the pipes kinda cackle loudly if thats the right way to put it! cheers!
