This thread fell flat, but I fear not!

Some news on the matter. I have more or less decided to go with the original headers after reading up on exhausts and what to look for.
Seems like wider might not be better as I first though when the engine isn't a high reving one. As a bonus it's the cheapest option too! Now I will save some money to buy the cans, headers, stage 1 and 2 DNA filters and a dyno run. Thankfully my bike was already fitted with a PC3 when I bought it. Probably all of these upgrades will take place next year but pictures will follow when I'm done!
