Fast Intentions exhaust is here!

You don't Have to reflash it for it to still function with the new mods.

However, your engine will benefit from doing so after all these mods. Right now it is taking the increased flow from the free-er flowing intake/exhaust and is using its current maps to regulate fuel flow. This can hinder the performance gains of these mods. If you reflash your ECU, then crank and let it run for 15 mins to 'Learn' these new flow rates, it will adjust the map to work with the free-er flow. If you have already done all of the performance bolt-ons you would best benefit from going to a shop and getting a tune done. That way you can pull the max amount of gains from these mods.

I myself just need pulleys and then I'm going for a tune.
