What's best to upgrade first?
Hello all, I bought my 2016 zx10r abs thinking I was going to keep it stock. That's now changed. I want to get a full system exhaust and flash the ecu. My dilemma is which full system should I go with. I want what will do the most for the money. Akra seems so over priced. There's got to be something as good for a bit less $. As for the flash, I was looking at woolich, but don't really know what to buy. Their website is confusing. Also, should I get a K&N air filter? Thanks for your input.
