Arrow twin under seat exhaust HELP

Or just remove the can and give the baffle a wack from the other side, it only takes two minutes each to get them off.

 

I'm looking for help, it's the first triumph I've had and I frikkin love it, I can undo the hex screw, and have removed the baffles, but I've heard that you have to have the bike set up or risk damaging the engine, please help as it sounds awesome without
Cheers fletch

 

Presumably you already have the correct map on for your cans fletch. There is no differing map for baffles in or out.
If you're unsure just download tune ecu from http://www.tuneecu.com/ which is free but you'll need a cable. Best from lonelec http://lonelec.co.uk/index.php?route=product/product&product_id=52&search=Triumph then put on the appropriate map.
