Akrapovic VS Muzzy systems: any differences?

[ScreaminKaw]

I'm replacing my Muzzy exhaust (ss header/mid with round aluminum can) with an Akrapovic system (ss header/mid with titanium can).

Besides gaining a huge muffler compared to the little Muzzy can and also gaining a quieter exhaust (should be more pleasant during cruising now, which will be nice), are there any performance differences between the two?

I've read in threads about some systems performing better than others, even though some say you'll never notice the difference. Well noticing or not is fine with me (as long as I'm not LOSING any power lol), but how does the new Akra compare to my outgoing Muzzy? More/less power? More/less weight?

I know it's all meaningless for street riding (as far as noticeable performance differences), but it'd just be nice to know what changes are coming to the REX that I probably won't be able to tell. I have a postal scale in the garage, so I can weigh the parts when the time comes to swap systems, but do any of you guys know any power differences between them?

From everything I have heard , on a stock engine you will probably gain maybe 2hp with the Ackro. If you had a modded engine (cams, porting, high comp) you will gain a little more. However you will have to pull the Ackro midpipe in order to change the oil filter .

and you have a cooler logo IMO!

Little power gain, sweet.

Little nuisance now just to change the oil, not sweet.

..and u gain 2 more HP w/the Tsukigi...

It's (2) springs and (1) nut, no big deal.

I know, that's why I said "little nuisance". Instead of taking me only a couple minutes, now it might take me a few minutes.

Muzzy complete round can system is a little over 11 pounds complete .
Good power over stock alot of bang for the buck .

Kerker ( first generation ) made for 1997 to 1999 zrx with race baffle produced great Tq / Hp but was a bit heavy @ 14.5 pounds . Due to its thicker steel . It can take a tip over were other cans wont survive .

Acropovic Stainless with carbon can was very nice . Quiet under cruise , and developed a nice tone under throttle . Not overly loud though like Muzzy , and Kerker ( supertrap )

Acro was around 12 pounds , but I can not remember for sure . Acro is my current pipe . Another friend has the same Acro , but in full stainless . His is a few decibels louder on my meter at idle along with throttle applied .

I made a quick release on my passenger foot peg mount by marking my bolt with pressure applied from the back of the mount . Then drilling it for a hair pin like used on the ZX12 rear axle castle nut . The carbon can is cool to the touch no burns from a hot can . Oil changes were quick , and easy .

I will have to pull out my dyno charts as I have many pulls with all three systems . The Acro is a few more hp up top but I think the kerker had the best curve of the three . All on the same dyno in similar weather conditions .

^ Thanks for the little write-up! Honestly, that's probably the most comprehensive exhaust comparo I've read for these bikes so far lol.

Nicely done!

I had a Muzzy meg for several years, now a ceramic coated, Kerker meg. I've not dyno'd the Kerker, but it feels stronger down low, whereas the Muzzy was better on top. Sound? the heavier Kerker gives it a mellower bark, that suits the retro look of the bike and pipe.. very "old school". The Muzzy has a different sound to it, just depends on what you like.

and then there is that quality welding you get with a Kerker..

i need to know these things as i will be making an informed decision by this christmass

it takes 30 seconds to pull the mid pipe, and you gain the gawd awful roar that ear plugs wont stop

the muzzy is a small tube dia systyem, it was built for the1100 motor,and it suffers when installed on an 1200. while the akropovic is three times the fit and finish as the muzzy. and if corning hard right you can drag the muzzy, not so on the akro, thats the main reason you have to pull the mid pipe to change oil, it tucked under the mid section of the bike.

Where does an Arata rate on power to these 2?

[Hogan]

Akra's got the crossovers which let it play nice with Ivan's pod kit

The smaller diameter SS muzzy header also seems to be ok with Ivan's air box kit maybe even pods ..

Larger diameter 4-2-1 Muzzy full Ti - not so good with Ivan pod kit.. ymmv

[saxjonz]

Interesting that this post is over two years old. I have both Muzzy ti/stainless and Akra ti/stainless, really like both very well. The akra is appealing to look at and is quieter. I like to hear sound but the Akra seems like it is a bit better constructed and thought out with the cross pipe sections. I really like both pipes, wish the Akra had more sound then I would be sold 100 percent. I like to hear a little engine when I spank her.

When i did the Muzzy meg, pods and jet all at once....woah huge differnce over the hindle can and stock header. Great induction sound and LOUD.

[Neggy]

Anything that is not the stock header with a stock can or slip on is going to be an 10 HP improvement before you even touch the carbs

arata big tubes lets it flow more up top end, and mid to upper torque, off idle mine seems to be a little sluggish to throttle until it gets to 3k, that was on a stock motor, now since i have gone zzr cams and porting and hi comp pistons she sings from idfle on up
