In favour of an after market exhaust for this bike: the standard system goes from a three into one into two, with the two heavy mufflers mounted high on the bike, to a three into one, and a low mounted carbon fibre can.
Against: some bikes can't learn a new system, they will need a new chip, or a Power Commander, or similar. Fortunately the Triumph can learn new tricks ('the fifteen minute tune up') and those potentially expensive mods aren't required.
Anyhoo, you pays your money and you makes your choice.
I put a low pipe on my 2011 675 for the same weight up high reason. And then spent several hours on the dyno with a af meter and a PC to reflash the ecu. I think you hot a bit lucky there. I never got the 0-15% at 4-5000 quite right but it was a minor inconvenience at speeds I rarely encountered.
Actually version one was too loud so we fitted a primary muffler which helped and still produced a reasonable increase over stock.
On my 765 the fueling was so good despite being euro5 I'm keeping the (fortunately under) stock pipe.
You could of course take out the baffle and strategically shorten or open it.
My old 1050 Tiger was so quiet it was ridiculous. I gave it to cycleworks and said make it like a stock 1990s bike. The design was a large can that was mostly empty with 3 Chambers connected with small pipes. We drilled a couple of holes to short cct some of the gas. It really made sod all difference.
I've been told. Dreaming`s free.
Think I'll go, back to sleep.
