    Linked from BlackDog - AdventureTank sells a 2 into one pipe and states that it drops 16lbs - Improves torque from 2500 - 7500

    KTM 990 Adventure 2010 - 11

    >>>>>AND NO Rejetting or Reprograming is required <<<< IS THAT TRUE?

    Does anyone have this with the Remus TI?

    Would this be too loud for forest roads? (Tennessee ... Not SoCal)

    I have the 2-1 mid pipe with the Remus titanium can on my 2008 990A. It is louder than stock but not too bad.
    There might be marginal improvement in the mid range, the big benefit is the weight savings and the reduction in temp of the can(s). Plus it frees up space for the adv tank. It is plug and play no programming required.
    Do it!

    Don't know the exact weight figure, but it is noticeable while riding, as is the torque bump at the low end. I also don't know about forest roads, but my Remus is indeed loud enough to annoy people in trailhead parking lots, which in turn annoys me.

    We've found that no jetting was needed when adding just a 2-1 to 950s, I can't see why it would make a huge difference for the 990's.

    Loss of heat and Weight is a great thing. Be sure to use a High quality silencer w/ a 2-1 as you are running more heat and pressure through it. I've had a couple ALUM silencers fail on me, before I new more about the Remus silencers, but my TI Remus is still going strong after many miles. I have about 50,000 on our 2-1 system and about 30,000 on my TI Remus.

    Dropped off my CJRacer 2 into 1 at the shop while they were doing a valve service and carb rebuild.... they said later over the phone they think the rear shock needs to be removed to get the two into two off? Any one know what truly gives on this?

    I removed rear wheel mudguard to get my 2-into-2 off. Removing rear shock was definitely not necessary.

    Not true. Worst case, they might have to remove the lower subframe bolts and swing the subframe upwards to make (more) room for the removal of stock H-pipe and fitting the 2-into-1.

    If they are convinced that they need to remove the rear shock to fit a 2-into-1, take your bike elsewhere OR better yet, DO IT YOURSELF. You will learn more about YOUR bike.

    What are some other good options for cans?
    I don't mind a little bit louder but don't want a drone at freeway speeds.

    If you are riding the forest, don't forget your USDA approved spark arrestor.

    I fitted a 2 into 1 from HT Racing. The kit included a FMF slip on that was made for a Yamaha R6. It fit perfect and it is louder than stock but I feel ok riding with out ear plugs. It does come with a spark arrestor that I have not installed yet.

    I'm running the FMF Q can on mine. Sold off my no longer used left can. It sounds about the same as my 525 does with a little more R's. I noticed no real jetting diffs. I happen to have the flex mixture screws and have adjusted them some for other tweaks. If anything, I feel like I gained more bottom & mid and gave up some on top. Since I mostly rid under 6000 rpm's no loss to me. :D

    I think "FUEL" which is a UK brand are pretty quiet.

    I would have thought that if you get any can with a removable baffle, you could probably make a larger baffle to reduce the sound some more? Worth experimenting for the cost of a bit of pipe, perhaps :)

    Don't install the spark arrestor if you are riding highway speeds (>5000rpm). The filling at the end of the FMF can will melt away and clog up the sparke arrestor. DAMHIK :lol3

    Ht Racing advised me not to run the spark arrestor if I am on the road, just off road riding

    Hi there,

    In regards to these 2 into 1 exhaust systems, I'm trying to organise parts to get the dealer to put one on to a 2010 Adventure in the UK that I've just bought. I've ordered a 2 into 1 adaptor from a company called "Adventure Spec" http://www.adventure-spec.com/shop/...vic-wings-leo-vince-fmf-neptune/prod_224.html

    So my question is when I order an after market muffler, do I also need to buy link pipes? Or do the OEM ones work? Say for example if I choose a Remus single can/muffler, do I also need extra link pipes to 'marry' them or is the 2 into 1 adaptor, original link pipes and aftermarket muffler enough.

    Also anyone in the UK have any suggestions for a place to source a decent after market Remus muffler/exhaust?

    Thanks in advance!

    Dave
