Was there any noticeable power increase? Did you need to remap?

You are not going to get noticeable power off a set of slip ons. Also remapping will not be necessary, unless you just feel the urge. If you get the 900rr setup then you would have to remap.

I'm very curious to see how the stubbies look on the 9er. . .post those pics! Both standard and stubbies are also available in titanium for $399 plus $18 shipping. Not bad.

Here are the standard length Titanium Slip-ons:

I wonder who makes the stubby system on that 9er. Anyone know? Just curious, they're not my cup-o-tea. They look cool though.

Do I get a prize if I can I.D. that bike + the original owner? Hmmm, struggling for hints that don't give it away too quickly. This could be fun.

1. That isn't any factory shorty system.
2. The really crusty guys from the old, defunct forum might have the edge.
3. Some careful scrutineering may get you started on your way.

Wait - More pics:

Do you mean on 919s or in general? I'm fairly new to 919s, but I saw a 10hp increase from a slipon on another bike, per dyno.

How was the torque curve affected? My understanding is that with decreased back pressure, you will see a slight increase in HP but a slight decrease in torque.

EDIT: I recall reading in Popular Mechanics magazine recently that lawnmower engine manufacturers are now assigning their engines a torque-based rating since torque is often more important than max HP.

I could be totally off-base on all this, but that's why I log into this site...Share what I do know, and learn what I do not. Of course the occasional argument is fun to watch.

Press Any Key To Continue.

It was a serious question, not meant as an arguement...

Peak HP was up 10hp, peak torque was up 3 ft/lbs. However, the curves weren't ideal. There was a 'flat spot' that could be felt when accelerating through the midrange. The 'flat spot' could have been fixed with a custom map, which I didn't feel like coughing up the $$ to get. If you're curious the bike was a Buell XB9S.

Actually, all Buell exhausts were compared on a dyno using a Stock ECM, Buell Race ECM, and a Custom Map. If you like to 'geek out' on torque curves and fuel ratios the results are available online:
ftp://ftp.americansportbike.com/outg...est_Report.zip

I've never seen a more complete comparison of exhausts for any brand of motorcycle.

I'm not arguing...just adding to what was already said. I guess what I was trying to say is that you will see gain, but probably not a full 10 - 15% gain by just changing the pipes. So...to get the most from a new set of cans, you would need to drop cash for a PCIII, and a run on a Dyno at a DynoJet shop for a completely custom map.

Winner, winner! Chicken dinner! I got too greedy with those extra pics? Cut down Remus cans and Hesa cowl, Buell conversion, modded F4i rearsets, etc. Kicked outta bed for a Husky SMR. Sad demise, too. Likely sold to Castman there in August 2007. Flipped again not too long after that, but involved in a DUI by the last owner and then impounded and likely auctioned. Too bad.

No. Basically controls & pegs from an F4i mounted to custom machined brackets that bolt to the 919 points. Pretty simple, just need a machine shop and accurate measurement to do it.

Photobucket is just fine and very EZ. Simply copy and paste the IMG code of the selected photo into your post.

Dang, those Delkevic stubbies are GREAT looking and sound great too, esp for the price! They tuck in close to the rear cowl. . .nice. ---No wonder they can't keep them in stock.

Thanks. I am very happy with the look and over all fit.

I like the sound also. Nice low runble at idle and not excessively loud under power. I am hoping to get some extended riding time tomorrow to see how they may have or have not effected perceived performance.

I was wondering when someone on the forum would get around to talking about and showing Pic's of them. I bought some myself on Ebay(278.33) shipped. I mean, it took me a couple days to decide about buying them because I have not heard of this brand and there were no write ups in this forum. So I went and did a search on YouTube and found some clips to get an idea on the sound quality and liked what I heard.
I found this tidbit doing a search on Delkevic Ehaust:
( Delkevic used to work for Akrapovic, making the pipes.They split, and now produce under their own name.The quality is good for the money., and they fit OK..) Anyway, I have yet to install mine because I tore my Bicep tendon and had to get surgery(no bike riding for a couple months).

Any chance of getting a video posted up with some sound maybe??

Yep...those look pretty sweet! I've been lookin to change mine out and came across these on ebay the other day, I wasn't sure about them since I never heard of them. I know the price is defenitely attractive.

well I've rode a couple times with the new pipes on and I can say they are keepers. Bike runs great and sounds fantastic. Not excessively loud but a very nice tone. I'm no expert so I can't say if it has any more power but it definately doesn't have any less.

Do or Do Not... There is No Try.

I visited this site after seeing these on Ebay to see if anyone has bought them yet.

Did you have any problems with exhaust stink before or after the swap?

I bought a set of stubbies this weekend, they are supposed to be shipped this week. I will do a pic spread/ write up on the install and performance eval when they arrive
