My plan was to do the sas and cat delete, and probably do the airbox - and then get the akra map. with the austin racing system this would be half the price of the full akrapovic system. but if the shorty will make the bike run less smooth its not worth it even at half price
A more common story is the shorty with the cat deleted sounded to much.
Id do a 1290 with the cat and a shorty exit but get self mapping tuner on board asap, spend the 700e on the pcV or another self tuner and have the power and smoothness and a little stealth when you need.
I put the fake one that they sell on eBay on mine. It isn’t quite as clean as the AR, but it is still a very clean look and pretty much exposes the entire rear wheel. IMO looks decent.
It is basically a short straight pipe, with the cat still on. Truth be told they probably have $30-$40 dollars in material costs in the thing (and no R&D), if that. Probably just an automotive exhaust tip with a shroud. But it is still a lot cheaper than a true name brand slip-on.
I mainly got it for the aesthetics and a bit more volume.
As far as power, I feel no discernible difference from the stock exhaust. I am sure there are some differences in the power curves if you put it on a dyno and actually tested/compared, but nothing I can notice in real world riding.
You still have the exhaust valve/flap servo, which creates back pressure.
It is just the right amount of volume for my taste. At a cold start it sounds kinda like a Harley, but after it warms up, it simmers down a bit. At speed/higher rpms I really like the sound.
I also have the fueling dongles installed which makes it easier/happier in a higher gear/lower rpm for those times you don’t want to be too loud in a neighborhood.
I wasn’t trying to put a bunch of money into this bike in aftermarket parts, like I have before, and it already has enough power for me. So this was an economical solution.
