What's the best bet for my 08 R6 as far as an N2O system ? Not really wanting to build a race bike but just want an edge !!!!!!!

you can find a single nozzle dry shot setup for around $300 from schnitzracing.com or multiple other places. You will need to get a PC3 or techlusion box to make sure you're getting enough fuel to compensate for the nitrous. I wouldn't just rely on or trust the ecu to add enough.

check out this site, has about the cheapest kits i can find

+1 on the PC3 or techlusion
