Hi and welcome Jonny, glad to have you along, hope you enjoy the forum as much as the bike! No, Triumph support their own aftermarket can (TOR) and the Arrow can with fuel maps, but most people here won't pay the prices Triumph charge for remaps (typically 20-30 mins labour @ £65 ph). The cheaper and more sensible alternative is to get yourself some freeware called Tuneecu and an OBD cable from eBay for under a tenner, that way you can remap it yourself, read and clear error codes etc, you don't have to be a computer whizz or a techie to do it either. Anyway its a way round paying Triumph. Oh and....
I've had both akra and arrow. Both sound fantastic when they're popping, much better than standard. Would say its down to personal choice then. Welcome along too.
Thanks for the info guys, got myself an arrow fitted it straight away, sounds bloody great, book in with triumph in a couple of weeks time for the mapping!!! Roll on summer[SMIRKING FACE]
