2 into 1 Exhaust ... Q

[Platypus-3in1]

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!

This is going to be my very next mod exactly.

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.

+1 I just removed my own using this method

Is this true if you are using a Uni pre-filter?

My jetting is stock except for needles in 3rd position and mixture screw 1 1/2 turns out (so 155/160m and 42p). Was running great, 0-4000'. After installing the 2:1 when I started it on the stand it was bogging.

I just did the valves and pulled the carbs apart to get above specs (I'd never opened them up before, previous owner made the clip change).

Was just curious as I added the pre-filter 2 years ago and bike still ran well after. Hence curiosity on whether the combo of pre-filter and 2:1 changes things?

[fishbird]

Try Adventure Spec...I think they have stock at the moment, couldn't have been more helpful in conjunction with KTM dealer.

[sidestand]

I have a second hand neduro link pipe and wings exhausts spare if any u.k guys are after a mod to there katoom.

my mods went this this order so I didn't see any issues.

1) stock to twin FMF pipes. -No jet changes required.

2) Uni prefilter - Ran really rich, Installed Head2Wind jet kit. All better.

3) Built 2-1 pipe and installed w/ single FMF pipe. Ran no different, just felt more bottom end torque.

4) Blew up 2 FMF Alum pipes- Swapped in a Remus TI , No issues since.

I did not do any Dyno checks along the way, but felt no difference in performance or power along the way.

Last Sept I put the 950 back on the Dyno at 70,000 miles. I got 86 Rear wheel HP, same as it did when I did #2 mod after jetting and 30,000 miles.

5) Oct to Now-
I'm running an open air filter system b/c I can't fit an air box. (AWD mod) I went back to a richer STOCK jetting. No dyno A/F checks done, but it felt OK on the 5000 mile trip to Moab and back to Milwaukee.


Does that clear it up????

I should learn to leave things STOCK.

[mdfehrmann]

My uni filter upgrade was easy with the Head2wind jet kit, no issues runs great. My winter project was installing the Cjracer 2 to 1 and a Remus Ti exhaust. Looks fantastic sounds great and made all kinds of necessary room on the other side. I did have to remove my inner fender / splash guard to get the stock "y" pipe out but 4 bolts later it was easy.

Pics to prove it...

Hey CJ
with all these inmates running Remu Ti pipes, what are the chances of supplying us wth USDA approved inserts? I know you are way busy but it looks like there is a market. Ill volunteer to test the proto.
