So for a few months now i have been tryting to decide on an exhaust upgrade and i've come to the conclusion that it needs to happen. however i have a few questions. i would appreciate any knowledge or insight you could share with me/us.
1. so i've decided to go with the Austin racing (AR) high slung gp1 can and mid pipes. how ever i dont think im going to buy the $1900 pipe that connects to the headers. is it foolish to not buy the header pipes? i was told that the amount of airflow you gain is minimal and your really only gain weight savings (i weigh 300lbs in my eyes it would be stupid to spend $1900 on a header pipe that would reduce my bikes weight by a few lbs)
2. i have been told that buying a can and a mid pipe that is a "decat" is considerd a full system, is that true and if so should i remap my bike? i plan on leaving the db killer and baffle installed. is it stupid to buy a exhaust and mid pipe and not remove the baffle and remap it.
3. i know very little on remapping however the information i could find from internet / calling ktm dealers is that there are two ways to remap. a ktm flash, and doing some sort of "power commander" would it be wise to remap the bike with just the decat can installed and mid pipes? if i go this route do i need to remove the sas? im looking for the bike to run its best i dont want to half *** this and let my bike run lean or rich.
4. if i do end up remapping the bike is there anyway i can do that safley without a dyno (or is a dyno needed to optimise the ratio?) if i go this far should i install a rott intake? i guess what im asking is at what point do i need to remap and should i do an intake aswell..? i relize i will need a power commander to remap via a dyno. what type of powercommander should i use? are auto tuners worth it? once i remap the bike is there things i need to change/ update/ check every few months?
my reasoning for buying an exhaust is becuase i think the stock exhaust is a joke especially for a 18k bike. i want the bike to run great and sound amazing. im not necessarily looking to pinch every ounce of power that i can get out of the bike. its fast enough i just want to know whats the best way to go about a decat exhaust upgrade. id prefer to not spend upwards of 5k to make the bike sound good and run good but i dont want to do more harm then good :/
thank you for whatever light you can shed on this topic.
Ok, first keep stock header pipes,just do a decat,and remove db killer in stock can(unless u want to spend $500+ on a can that doesn't improve performance and only removes about 3lbs) then u can remove emissions & add fuel dongles,or u can go pcv and download one of there maps to start.
It all depends on what u are looking for in regards to performance and how much u want to spend.
okay so what your saying is i should do a decat system (AR can / mid pipes) remove the sas and add a pcv with a predownloaded map for the system and it wil be fine the bike will run with a proper fuel to air ratio for the added air flow? (i hate the stock can)
Arrow can with an arrow mid pipe,ok,pcv comes with fuel dongles,SAS will eliminate popping
All good...There is a free map u can get from Powercommander that will work (#3) ....AFR's
Should be fine....I did similar mods ,but used a Remus decat and just removed the db killer in stock can, and used #3 map....quite honestly u can just use the KTM full akra re flash (installed by your dealer),and ar can& mid-pipe,I did just those mods initially and did a dyno to check afr 's and they were ok....if you intend add a rotty air box u should use the pcv with a "Kev map".
The ar exhaust is different enough that I won't try and talk you out of it but if you buy one of the decat link pipes you may be surprised how nice the stock can really is. I, personally was disappointed when I swapped the Akra from stock and there was no increase in spl ant least my can was free. my bodis link pipe opened it up quite a bit and I heard a stock can with an arrow link pipe I thought was even a bit better sounding. My akra was like Drnick said 3 lbs lighter and losing the cat will lighten it up another 13 lbs if I remember correctly.
I've done many an exhaust mod on all my jap crotch rockets,because "they needed it ",but this is the first bike I've owned, that the stock muffler/can is staying in place!,I refuse to pay
$500-$600 on something that has NO performance gain,other then u lose a couple lbs!
If you look through the stock exhaust,it's straight through! Except for the so called DB killer,it's a straight through exhaust glasspack!
I agree with the stock exhaust can being no better than an aftermarket one besides weight. But. My issue is that to open up the bikes exhaust the main hindrance is the cat. So you get rid of the cat. Now you have to do an sas delete. Now you must do a reflash. Than pick which link pipe you want. And stay with the stock can or not.
If i I touch the exhaust I might be inclined to just spend th money on the Ktm/ akrapovic package deal that was designed start to finish for this application. But the cost of that is a tad high. About $200 per horsepower. Horsepower that in my opinion is not needed for street riding.
$200 for Remus decat,$40 for rotty fuel dongles
$50 for Akra remap flash( dealer installed),& throw in the SAS,so you don't get that annoying
Decel popping....and if your at sea level,and ambient average 70-80 temp,you should be ? ok?
I had the same problem at first,dealer first said I had to buy whole Akra exhaust
Which comes with a"code" so they can install akra/ktm map reflash,but I was insistent
And brought a printout from another website ,proving it can be done! Side note,
Most KTM dealers & and techs are new to this (mine was) so call around and ask first
If they have done this without the purchase of the whole akra exhaust system.....dealer charged me $50 for reflash,took 10 minutes
Thanks for info. I will make some calls tomorrow. I was searching internet and found more info about it. I think there might be other dealers I can get this done at if I can't get local ones to do it. I really want tha map . I'm running Remus de-cat with slip-on . The bike is running good . I would like benefits of map.
If your not going to go the route of buying
A PCV and with the mods you've already done
Buy the rotty fuel dongles & the SAS and the bike will run much better(that's what I initially done)
Awesome great suggestion and info. I was not sure if I was going to get PCV. I had the bike dyno'd after de-cat pipe just to make sure it was not lean. It was fine and was producing 150 hp so I was happy. But I would like to see a bit more if I can make bike run better. I had looked at Rotty SAS kit and dongles. I will order them after akra map. I already have the KN filter but did not want to install until I figured out what direction I would have to go to for mapping. I had also read that you get better results if you had akra map as base map before doing PCV and rotty kits. I don't recall why that was the case but I figured it would be better to have that map and decide how much more of the beast I want to unleash. Thanks again for info.
That is good to know. It helps in deciding which way I want to go. Once I get this akra map thing resolved. I'm thinking I will just go ahead and replace airbox while I'm removing SAS. Instead of installing KN filter and being disappointed in results.
Earlier this year I met a guy with 1290 at bike hangout in Georgia mountains and was impressed with full rotty treatment on his duke. It ran much better than my basically stock bike. He had full rotty kit and running Austin racing exhaust and I think he had Austin racing map. At the time I thought my stock 1290 was fast and powerfull until I saw what his could do. Wow did see the potential for my bike. Not that I needed all that ..but it was impressive.
Rotty airbox & 2 80mm stacks is the way to go! But that will need a PCV!&
Map(there are a maps out there for free)...so total approx cost for all that
Approx $160 for two 80mm stacks,
Around $250-$300 for PCV,& approx
$350+ for rotty airbox....if ya wanna go fast!! Ya have to empty your wallet?!
` if you do all that plus the AR decat and mid pipes and sas removal, must you do a dyno run on your bike? or can you just have a pcv with an AR mapping predownload plug and play and be good to go ( no problems with bike)?
I like it:grin2:. Thanks for those recommendations. Those prices are not too bad considering that I won't need to by full akra system. LOL just my way to justify it. I had seen the stacks on web site but was not sure about them. It is good to get a confirmation from someone that has them. Your right I think I will just give them my wallet..because I wanna to go fast>
Drnick thanks for help on this. After some phone calls I was able to find a dealer to load akra map. I talked to 3 dealers. The one closest one was where I bought my bike, they said could do it after I pressed them about but they seem generally confused by my request and they said I could bring it in and would charge me $140 plus whatever Ktm wants to charge?. They also seem to indicate it could be more if it took longer.? . I found another dealer about a hour away and they were familiar with akra load and had done several. I have appointment for akra load next week. I'm looking forward to that. I have been checking out rotty site and I think I'll be ordering the stage 4 kit with extra velocity stack. They have free shipping till end of end. I'm still thinking about whether get stage 4 or I can start with lower stage. I guess I'd better get wallet out?
It only cost $50.00, $140.00 + is a rip off! Stay away from that dealer! Most if not all KTM dealers ( who know what there doing) only charge $50.00. Again if you go for the rotty intake , whatever stage, you should also install a pcv with proper map.
Thanks guys , I appreciate the info. I will be getting a PCV with whichever rotty kit I get.
Yeah when I heard $140 + for map I knew this was ripoff. I was surprised since I bought the bike from them. I'm glad I have not had them do any except replace last of tires. They were reasonable and I thought I would build a repore with them. That has definitely changed.
Do you know how much this bike from the factory saves you in $$$$$$$$$$ ?
Every bike I've ever purchased in the last 10 yrs ... 5-6 got Ohlins suspension and a dyno tune ... that alone is at least $3500 per bike! The new SDR ... is already saving me coin! WP suspension is on par-
-Gutting the suspension -I think the electronics are already on it !
Hmmm obviously there are people on this website that have tons of expendable income
$3500 per bike for shocks and dyno! YOW!
Me thinks I shoulda stayed in this business ?
