Akrapovic or Remus

Hi everyone, I would like to change my exhaust system on my 2007 GS 1200 to have better performance. I'm not sure if Akrapovic is better as a Remus. Anyone have expeience with those 2 exhaust?
Thank you

In all seriousness, if you want a bit more performance, leave the exhaust alone and richen the mixture with a pair of LC-1s from Innovate Motorsports. Or try a powercommander V.

These boxers already get plenty of air through the engine. What they need and be fit from is 4-8% more fuel. The stock bikes are too lean and the exhaust won't change that.

Definitely Akrapovich, I put it one together with a BoosterPlug and I have to say the bike runs better...

A friend has the top system. Sounds brilliant and apparently makes more power than the single can system. He can do power wheelies easily in 2nd gear and loft the front end off bumps in third.

Iíve got this set up on mine. Came with the bike so I canít comment on power boost from OEM, but they sound awesome and every BMW rider will look at you when you pull up!

I replaced the OEM headers with Remus (no CAT) and later replaced the OEM exhaust with Akra (got the Akra for free). '09 R1200GS. I have ridden extensively with both baffle in and baffle out. On balance I prefer baffle out. Bike runs smoothly and there have been no issues except a little decel popping (not much). Oddly, mileage per the bike's computer has improved somewhat (baffle out -- no improvement noted with baffle in). If there is any performance gain it would probably be to reduced weight of the no CAT and Akra can. Bike feels livlier and runs just fine with no add'l mods needed. ECU adjusted to the set up with no problems.

Esthetics Trumps Performance and Common Sense is Nowhere to be Found

I too dream of changing my exhaust from end to end. I also dream of modifying both my A/F and ignition maps. I try to convince myself I can't live with the lean conditions that effects certain throttle responses. Back in the day, I started riding in 1965, YOU adjusted to the bike. You didn't go out and buy magic bullets because they didn't exist. If you sit down and think about it, what is it you really can transfer to the way you ride after put on all of this "stuff?" There are some bikes you can make significant improvements to, but IMO the GS AIN'T one of them. To steal from a friend's forum name Just Efn Ride.

You can keep telling yourself that. But I saw firsthand what the Akra full-system duals and a PCV did to my friend's '08. Turned it into a fire-breathing beast!

The R11xx and R12xx is delivered running lean, and as a result it is easy to make significant improvements by adding fuel.

Here is a GS story: Richer Mixtures on R1150GS.

What every good exhaust manufacturer recommends is to add fuel, which is exactly my point. If you want performance, add some fuel, a $160 upgrade. Then if you want a different look or sound add a $1,000 exhaust.

I will second that, on my 2012 the exhaust, air filter and power commander with a custom dyno tune has made all the difference in the world! I left my 2010 GSA motor bone stock, there is no comparison. People make lots of assumptions based on what they read etc. come take my bike for a ride and then tell me there is no difference.

I did the Akrapovic full race system with no cat but I still have the flapper mod.

If you are in the Portland area come ride it and then tell me there is no difference. You will be amazed.

I wanted the duals like that for mine (2102) but they only made them up to 2009 so I was stuck with the single canister version. Still sounds great but doesnt look as good!
