That's an awesome site, great prices! That's exactly what I'm looking for. they even offer a cat free header pipe! I've e-mailed them for some info. (I'll post back once I hear from them). Much thanks!
Let me know what you find out about this cat free header pipe.? :s
I would get rid of the cats. Also you mentioned you "didn't want to get into the tuner thing," if you meant that you didn't want to discuss it here that's cool. But if you are not going to add some kind of fueler I would reconsider as these bikes are already lean from the factory and even more so after you free up the air flow a bit. Good luck deciding what pipes you get.
