    Looking for some baffles for the twin arrows I got for my 2011 speed triple for MOT purposes any ideas where to get them from

    Getting genuine OEM Arrow baffles is highly unlikely, though that unlikelihood probably hasn't stopped you google searching for some. I would think your best bet is to measure (or search for) the internal diameter of the Arrow can's outlet and look for something like these

    to fit/suit. You may need to do some creative mods to secure them into the cans but I'm guessing they won't need to be long-term secure - just long enough to get to, through and from the MOT!

    What's the arrow cans part numbers?

    I have some, with baffles in, but don't know if they would be the same as fitted to a street. If they are, then I could post measurements and a picture.

    Mine are 'baffles out' and my local MOT place never even mentioned them. Think the Arrows are relatively 'quiet' compared to some other cans.....

    Ok mate cheers a lot of people are saying they run with no baffles and say they are not excessively loud so I think I will just put them on and see how it goes

    Likewise, I've run twin Arrows without baffles more or less from new on my 2015, now been through 5 MOT's without a mention.
    I have the baffles (but not for sale), the diamond shape flange required to fit them will limit your options.

    I'll have a look tonight.

    On a 675 street they have a lovely overrun pop on deceleration when baffle less but, the drone at constant speeds around 50 mph does my head in hence I run with them in.

    That's what gets me with loud pipes - the long trip drone. Almost as bad as having a toothache even with earplugs.

    The DB killers stay in my Arrows. Still sounds good.

    Just enquiring if the baffles from the arrow twin exhaust on a speed triple 1050R 2016

    would fit the arrows for the 2011 to 2015

    Thanks

    I can't give a definitive answer, but I would guess so. At some point they started fully welding in the baffles, this was to satisfy EU regs that mandated they should not be easily removable. A forum search should bring up the procedure some have done to remove the fully welded in baffles. Mine were held in with a single screw with a small tack weld on the screw head, so were easy to remove. I bought them around 2016 but were old stock that a Triumph dealer was clearing.

    Just to add to my previous post;
    The 675 street Arrow baffles are fastened in by a circlip so it sounds like a totally different arrangement.

    Ugh. The first thing I did to my 1050 rs was to remove those huge ugly things and replace with a competition werkes can and then retune.

    Looks better, sounds better and 15 less pounds above the COG
