Are you original owner of those slip-ons, how old are they?
I must have misunderstood about 2 into 1. I thought that they are designed for top end, and low and mid suffers...

If they have been repacked recently, and have no damage and minimal fading of the carbon, $500 is way too low. You could probably ask $700-800 and get it.

As far as I know, you have your thoughts on 2-1 exhausts backwards. They have dips in the midrange and higher top end power.

Did you read this part about 2-1 exhausts:

I have seen many 2-1 systems yield better topend hp & weaken the mid-range like on the Erion Superhawk & numerous Hawk GT systems. *That's not to say that with enough piping & tubing you could get just about any result ya want, but it will most likely be a point of diminishing return as the overall power output will most likely be significantly lower (if you were to purposely build an exhaust just to prove a point)

I firmly believe that on the HRC Superbikes that the extra length of piping is taking the jerk out of the mid-range making it a less powerful hit of power & thus more useable, but not "more" mid-range power. Along with that I suppose that top-end may be suffering some, but with 190hp on tap I guess you could stand to lose a couple here or there.

Either way I think alot of people are going to be dissapointed when the final product comes around & it doesn't give you this miraculous mid-range power gain that you have all been dreaming about.

Several manufacturers are currently working on 2-1 exhaust for the RC51, once some of them are on the open market & we can test them then I may need to revise this page, but until I am proven wrong I will stick to what I learned over the years.

Update 06/05/02: The Erion 2-1 full exhaust on the 02 bike is producing dismal power curves even worse than stock & has several issues with overheating the motor as well as scorching the single cannister.

Update 07/18/02:dyno charts of the Erion 2-1 with a terrible mid-range dip

Jardine has admitted that they are having problems with the mid-range with their 2-1 system & Arrow is being very tight lipped about their 2-1 after having made a big showing of the prototype many months ago which to me is most likely indicative of their failed attempts or at least performance issues stemming from the design.

UPDATE: Jardine has released their 2-1 full system & the performance numbers aren't bad, nothing spectacular, but no major drops in performance either. A few owners have commented that it leaves a flat spot in the mid-range, but overall with a price tag of $499 it sounds like a pretty good deal for those that want more performance than stock, less weight (credible reports have it at a whopping 19lbs of weight savings & a price tag of $390) & something fairly unique dyno chart for Jardine 2-1 another dyno chart for Jardine 2-1 supplied by an actual owner (the mid-range dip is pretty severe on this one). There have also been numerous issues of the welded tab breaking off on them as seen here 2-1 Jardine broke

600 is a fair price..... i would keep them though. Sounds like you made your mind up, you'll get 600 easy. let us know how you like the Jardines in comparison.

Why would you trade down ? You seem to keep your bike in pristine condition. Here's a Jardine system for sale http://pittsburgh.craigslist.org/mcy/2792389612.html Take a look at the discolouration on it.
I had a 2 into 1 Jardine on my bike when I bought it. There was such a bad dip in the mid range it felt like it had a badly tuned 4 barrel carburetor. Although it didn't have a power commander on it yet I put a stock header on it with 2 into 2 slip on's and sold the Jardine. I don't think your going to be happy with the Jardine 2 into 1 system.

I have the Jardine 2into 1 set up. It's loud as shit tho. I cut 4 inches off so the end would sit flush with the tail. Plenty of power all over for me

Getting top dollar and selling something for what it is worth are two very different things. I agree that paying it forward is a good thing. I've sold a set of almost mint high mount leo vince titanium cans for $450, and an Ohlins shock for $500.

Heck, you could price those cans at $900 and get it, eventually. I just have to agree with cantonrc here. You are selling a set of discontinued, highly rated, expensive cans to get one of the cheapest exhausts out there. At least do yourself a favor and buy the Jardine before you sell the Akropovics, because you won't be able to find another set for a while, and not for $500 or $600.

+1 Keep the Akropovics till you know how you like the new setup.

I have a 2-1 sitting in a box at home with a Black dragon can. mid pipe is a little smashed but with a Tune I got rid of the massive dip. I would be willing to sell it. for pretty cheap if you just wanted to give a 2-1 a try.





there are the only pics I have on the bike.

i am running the jardine 2-1 pipes currently (pictured). they sound like a demon garggling whisky and spitting fire :)



i recently found this dyno chart from an owner:


this is the dyno chart from jardine:


so the owners chart shows a clear drop in the mids but increases in the highs where jardines chart only shows slight dips in the mids.
