    Just purchased a standard 2010 Bonneville. so purse strings pulled tight by the wife, I like a nice sound from a bike so until I buy TOR,s can I drill the shit out of the standard ones. when I had my Thunderbird sport I welded a large drill to a rod and drilled a hole through. what im asking is do I need to remap etc. cheers

    Hi FF, if you change for any exhaust that sounds more fruity than the std.one, it means it is more 'open' and therefore flowing more air.

    A good, cost-effective approach is to do the popular airbox mods to allow more airflow into the engine at the same time as a change in exhaust, then do the re-map to take account of all the changes at one go.

    Have a look at www.squaredeals-ltd.co.uk as they do 'silencers' for Bonnies from £100 to £600:eek: for your pleasure and enjoyment! :D:D
    Norman Hyde seem expensive, and Sprint Manufacturing would appear not to do any at all, which seems surprising!
    Can't think of any other suppliers off the top of me head!

    I liked the RE Clubman. It ticked a lot of boxes ... I like the café style and the sound was proper, an old bike with up to date brakes and electrics. easy starter and no oil drips. I wanted a bike with longer legs and smoother at 60-70 mph. I think it would make a great second bike in the garage. but needed the part ex dosh

    I've recently put a pair of these on my T100 and like the sound, the way the bike feels and the price. I bought mine directly from an Ebay seller for £73.

    As I write this I'm waiting for a delivery of a new rear inner tube, so even though I'm very happy about these pipes I can't go and ride - not that I'm frustrated or anything :mad::mad::mad::mad::mad::mad::mad:

    Hi FF, my bike was already re-mapped,as I've done a variety of mods on the airbox as well as VERY free-flowing exhausts before these latest ones.

    Might I make a suggestion? Once the new-bike-purchase-dust has settled and you start to think about modifying her motor, do a few mods at the same time then go for a Triumph Twin Power (TTP) re-map.

    The popular changes to give the bike better running are:
    1. Removal of the Air Injection (AI) system - this is part of the factory anti-pollution system and makes the bike run hot and blues the exhaust downpipes. Also can popping on over-run and throttle roughness. Costs peanuts to remove.

    2. Removal of the O² sensors - this is another part of the factory anti-pollution gubbins and definitely causes low throttle opening snatchiness. Cheap to remove.

    Mods 1 & 2 really should be done at the same time imo.

    3. Remove the air restrictions related to the airbox:
    A. the rubber snorkle -file it somewhere far, far away;
    B. Replace airfilter with DNA type;
    C. Remove airbox baffle plate

    These mods allow the engine to breath better,therefore more oxygen into the motor.

    4. Change the std. pipes for more open,better breathing versions.

    If these mods are all done at the same time, 1 new map from TTP will take care of the lot and the result will be a smoother running, more powerful, more torquey bike with better mpg.

    Also you would be wise to download a free program called TuneECU and go here to do some reading:

    Have fun :):):)

    I'm liking what I'm reading Big Lad, mine pops and bangs a bit I'll have to have a closer look at the AI system removal, and the O2 sensors.
    Is there a link to a "how to" any where on here.

    If you do a Google search for "Bonneville AI removal" you'll find shitloads.

    AI removal kit ordered from TTP, also gonna open up my air box to check what air filter is fitted and possible baffle removal.
    Then see if I need to order a Breathe air intake cover.

    Just out of interest. What's the postage like on ebay to France. It's a killer here in Ireland
