So after reading old posts and threads regarding aftermarket exhaust for the VF500, and after searching everyday for an Aftermarket exhaust on Ebay and finding NOTHING....I have 2 questions:

1. a) Can I just get 2 Slip-ons made for a similar cc bike and have them custom installed by myself or some Muffler shop?
b) ...and will this require rejetting of the carbs?

2. a) I read about drilling around the main exhaust hole in the can to increase sound...will this hurt performance?
b) Will this also require rejetting?

I just want to have a little more sound from the bike to make myself known in traffic.
