Akraprovic exhaust

[bbbvito]

Thinking of changing my std exhaust on my 2008 gs1200 for a new akraprovic

Whats the views -

Is it worth the 500 quid price tag ,

Is there a cheaper place to buy one from BMW = 499 Nippy norms =500+

Sound / Performance is it much improved.

Is it different from the 2007 model

All i can gather is that they are like rocky horse s--t to get hold of second hand

 

[Slowdown]

I'd spend £500 on trackdays, or going to Morocco or Norway or something a bit more tangable than a 2 foot metal tube.

But it's your cash - have you listened to the MP3 files on the BMW site ??? They do sound nice, but not £500 nice, to me at least

I have an Akra can, bought on here from a fellow tosser Sounds nice but not a whole lot changed on performance. Most would recommend changing the headers to Remus and keeping the standard can. This seemingly does give noticable performance gains in the mid-range.

 

[GSmonkey]

Spend the cash on headers and a second hand Ti Remus. I did this for £350. Full system sounds the business and actually improves performance.

Had Akropovic can on 1200GS and then on 06 GSA. Sounds great and does free up some performance (or do you just ride it harder cos it sounds better?) Then put it on 08 GSA, but also put Remus headers on to get rid of cat. With baffle out bike was too loud (My other bike is a ZX12R with race Akro system!) and bike bogged down and cough on fast throttle opening. Put baffle back in can and runs fine, pops on over run and is much lighter. However did this a zero miles so can't say whether improved performance is 08 vs 06 GSA or the exhaust....

I have an Akropovic Can and Remus Header on my 05 1200GS. The Can was too much money, but so was the Bike too. Anyways, I like both of them.

As had been said, getting rid of the Cat by putting on a Header is what opens the bike up.

Yes know what you mean 500quid is alot too spend on a bit of metal! (or is it )

Cheers anyway

I have one although I got it for almost nothing, someone hit the bike and lightly scratch the stock exhaust, Mr. BMW dealer said better replace it for the akra, only an extra 100 notes.

It changes the sound of the bike completely, I've got the baffle out and I don't notice any increase in power, but it does feel faster or maybe just sounds faster.

Changing the headers is next on the list.

 

[Robbo1200ADV]

Remus Headers +Akro pipe -baffle = Mucho FUN!!! Feels sharper less like a domestic appliance and pops and bangs on the overrun nice snarl on full throttle.No faster but feels it!!

 

[John Armstrong]

Got a Bos for £200 IIRC, that was a reasonable performance / sound / weight option IMO.

£500 for an exhaust, which apart from having a cool name and a slightly better sound does what?

 

[Sgt Bilco]

Any power increase come from the change of headers. New headers with the standard exhaust also improves sound if that is what you are after.

Akro end cans are good but you are paying a shit load of money for a name.....

 

[WindyChuffer]

Akro Carbon can on mine with baffles out. Sounds really nice. On a long trip I'd put the baffles it, but round London its perfect without them. Baffles slide in and out so easily.

I noticed better mid range with the can compared to the original, like a flat spot being removed, but no idea if its true or just in my head. But I'm happy.

Remus headers + Akro can on next GSA arriving in cple of weeks...

 

[ExpatinIstanbul]

Standard headers, no cat, Akra endy on my '05. Feels a bit perkier, but again that may be because it's loud, oh so very loud. Putting the baffle back in soon.

 

[Sgt Bilco]

Just to put the cat amongst the pigeons here which may help you save a lot of money.

All end cans use the same basic internals because it`s neither a black art or rocket science so they all do exactly the same job i.e make a nicer sound and look nice and shiney! The cans do very little, if anything for performance.

The only differences are in the bracketry, the odd cosmetic addition and finish i.e titanium or carbon fibre.

With the bigger manufacturers like Akro, Remus etc you are paying a large percentage of the purchase price for the makers name on the can.

 

[talonfs]

Not to seem ignorant,
but does this mean in theory you can use any end-can that takes your fancy providing you get the bracket and connecting pipe right??

for example could I use the end can from a R1200S on a K1200S????

looking forward to informative replies.

Bilco if this is right why in Bike (Ride(?) was one or the other) magazine dyno tests on ZX12R does Akro system produce 15 bhp gain and Remus and others on 5-6 bhp? I agree a can is probably the least important bit but if doing system or down pipes, shape, internals etc all make a difference.

Maybe they (the more powerfull ones) have diffferent views on the legal noise levels, just like Harley and Ducati.

I suspect they are using full exhaust sytems and not just end cans which will obviously make a huge difference because they design the "enviromental" issues out. The manufacturer has to design his system to comply with TUV and emissions where Akro etc go for power. It`s a different design philosphy. I know that a good race system increases the power dramatically but costs a fortune.

I`m not talking about race sytems here but purely end cans. However, if the end can contains the CAT, there will be a difference.

My point is that a simple end can change, specifically on a GS, will not increase the power by much, if anything. It`s the removal of the CAT which makes the difference. Because of this, all end can makers for the GS and bikes with the CAT elsewhere, use the same basic spec because there is no point in wasting money.

As long as the CAT isn`t in the end can, I`m guessing (I don`t know for sure), you could use any end can on any bike.

The only thing you have to be aware of is the OEM cans may contain more sound deadening and other forms of restrictions to confirm to emission and noise laws.

My point was all aftermarket cans for the GS are basically the same

An educate guess here is that this will be correct for similar engine size / number of cylinders. That is a 250 single wouldn't work on a 1000 cc single, or a 600 four cylinder engine exhaust can wouldn't work properly on a 600 cc single, IYSWIM.
