WI Winter Project Plan

[hallada]

Evening folks...been looking at many of the bikes on the forum and come to realize that I really need to make some upgrades this winter while my '08 1125R is laid up waiting for the ice to go out.

Seems like everyone gives big respect to the EBR ECM but the house divides on which exhaust is best.

I am skipping Christmas and going to do both this winter but I am unsure on a direction for pipes. Looking for the a good bit of "wake up the neighborhood" roar and trying to avoid the big silver can sticking out the back...

I know that there are opinions out there on the perfect set up and I would like to hear them...

While picking up my Race ECM from EBR I was told to go with the Barker exhaust and matched ECM. I for one am not a huge fan of the look of the Barker but the bang for the buck has me pretty much convinced that, that is the route I will be going. For sound I have heard that the KEDA systems are amazing as well as the Drummer. My ideal setup is the full exhaust from Free Sprits..

the EBR ecm is tight, as for exhaust sir, keda-design all the way, keeps it under the bike, a bit louder and gains hp, a little more than the drummer but more aestically pleasing. i believe is what youre looking for, i'll post a vid of mine when i get it on the bike,

I have the FMF-apex on mine. I think it looks good and sounds pretty wicked too. however it isnt the best on power (nor the worst)... however, if you are more concerned with power output, have you seen the test numbers?

You can find HP rates with the EBR ECM here, as well as a sound board of each of the pipes. Do some research first, and decide from there.

Hope this helps, the Barker is (according to the tests) the best performance wise.

The one thing I haven't done to my 1125 is an exhaust and I am still torn on the issue.

I don't much like the look of Barker's, but it is certainly the best bang for the buck. I do like the Jardine and to a slightly lesser degree the FMF slip on but too many others perform better. The Drummer is nice but overpriced IMO. I really like the KEDA RT-3 and RT-4. They give good gains and aren't too expensive and look awesome, but if I can get a full system I would prefer it.

I am disappointed that no full systems were tested in the ASB comparison, and EBR only offers an ECM for his full exhaust. I would love a Free Spirits or FMF full exhaust, but getting the mapping will either mean a Power Commander V or having Twin Motorcycles monkey with my stock ECM, which is the last thing I want to do.

This is good stuff guys...

Sounds like really could be a contest between the Barker, Drummer and the Keda-RT 3 or RT4.

From what I can tell, EBR makes a ECM to match the Barker and Drummer but I am not sure if the Keda exhausts are plug and play as the Barker / Drummer seem to be. On their site they mention that "Tuning is Highly Recommend" and I am not too sure what that means exactly...? Really trying hard to keep my bike out of the shop and get comfortable wrenching on it myself if possible...

Appreciate all of the insight and links to helpful info...

My understanding is that they mapped a KEDA can or two this summer. For some reason it is not available on the website yet, but it should be soon. Of course, been hearing that for a while now. I've also heard that the generic EBR ECM for slip ons and pump gas works well with Deans pipe. You can get one and for a fee have it remapped with the specific map when it is available. Any richer map should be an improvement over running the stock map with an open can. Al said in the ASB test that he wouldn't want to run the stock map on his bike with a can because it comes out way too lean.

Highly recommended is exactly that. It will run with the stock ecm, but it's lean and needs a lot more fuel than what the stock ecm will adjust for. What I make is as "plug-n-play" as any other pipe out there, but will potentially make more power than just about any other system available on the market. I sent in 2 pipes for the shootout and they both just barely edged out everything to take the top spot for hp and torque. Yeah, it's just dyno numbers, but when one shop/guy/dyno does it all on the same bike for 3 days straight with tightly controlled conditions, that says something.

These are dyno charts direct out of the shootout report if you haven't read it yet. One took the top spot for hp, the other took it for torque. I'll stand behind these numbers all day long, I've seen the exact same thing on other dyno's, including the Superflow dyno at EBR.
If you look at about 8k rpm, the spread for both pipes is 20+ hp over stock and 12 ft/lbs higher for torque. If that's not enough to get you moving, then you need the EBR full race exhaust. That's about the only way you're going to get more out of an 1125. The big difference at that point is going to be how much $$ you've got. Mine start at $549 for the RT-3, the full race is $1800 from EBR.

Now, after all that, I will say this for sure. Regardless of who you buy an exhaust system/slip-on from, get the race ecm. Hands down, it will be the best thing you can do to/for your bike. It will run like it should have from the get-go. They smooth out the fueling so much that it actually feels down on power initially because it's not so abrupt with the delivery. They don't have tunes for every pipe combination out there, but even so, get the ecm. It's worth every penny.

Hey Dean can you list your pipes for me in db's, quietest to loudest. I am looking for a little more sound but I dont like something super loud like the EBR race exhaust. Are you tig welding ur pipes?

 

[d_adams]

I think Al tested them and they were 98-99 db at idle, maybe 112-115 db at 4 or 5k rpm. They're pretty much all the same at idle to me, the RT-3 is the loudest, the RT-2 and 4 are in the middle, the RT-1 is the quietest, at least to me. Tip angle and style does have an effect on how it sounds also, the slash cuts are a bit louder to me. I only have a tig welder, so yep, that's what the welds are. I'm not perfect at it though, they're more for function to me. I weld a little heavy sometimes and I know the welds are solid.
