    full exhaust, filter and a dyno tune on gen 1

    Thinking of a full exhaust, filter and a dyno tune on my gen 1 but concerned about the exhaust noise level. Personally I do not like owning a noisy bikes. If I use a DB killer will it keep the noise down to a reasonable level and will that kill the gains from the exhaust ? Will the exhaust be an realistic legal issue in other EU country outside the UK on vacations ? The dyno tune is a bit of a no brainer to me but is the full exhaust really worth it ? Has anybody else done these mods and what should I expect ? Is there anything else I really need to do before it goes on the dyno ?

    Full headers will be loud, no way around it. What fuel mapping are you getting done, PC-lV, Brentune, Rapid Bike Evo or similar..??  DB killer helps but will just about negate any gains. Some European countries won't allow non standard exhausts, some won't even allow a stock XR exhaust as they're quite loud to begin with.

    All EU countries are outside of the UK now.
    Cannot see any problems here in France as we don't even have MOTs nor road tax on bikes, almost anything goes.
    The trouble is that the UK is now not in the EU so who can be sure how EU countries police will treat British registered bikes.

    Thanks Smithy. So would you recommend not bothering with the exhausted and filter in my case and just going with the dyno tune/ECU flash. what can I expect to gain from that

    I plan on getting the bike on the dyno at BHP UK and letting them write a custom map flashed to the ECU. They have recently posted a stock XR they have just done on there web site and on U tube which looks very impressive.

    Posted plenty on here about mine....Akra headers/MIVV end can PC with custom map with photos of the dyno runs, loud it isn’t, have a bike with a Rexxer map runs well but prefer the feel of a PC, the end game?? It isn’t about HP it’s bottom end fuelling, can ride mine like an auto, will pull as clean as a whistle two up in 6th from under 30mph, and no glitch at 4250 revs curtesy of the TUV.

    So if yours isn't noisy, I'm guessing you've got a DB killer in?

    Considering we've got two bikes are full systems really worth the cost if we're going to put a DB killer in and want to take the bikes around Europe? 

    Any chance you can post your dyno charts and opinion?

    I have dyno tune results for a standard XR bike with a custom which looks well worth doing from BHP UK

    From my experience the re-map will make the bike much nicer to ride, better throttle response and a few more hp here and there. The decat headers give really big gains in midrange, quite often in the 10hp region and another 4 or so on the top end - just look at the Akrapovic website for before and after graphs as it really shows this. Combine the re-map and the headers and you have a great, strong engine. But you will need an end can with a baffle if you want to keep the noise down.
