Hi Guys,

I was wondering if anyone has had any comparable experience with mufflers that utilise a smaller can (along the lines of SC Project, Austin Racing, Leo Vince).

I've recently fitted Delkevic headers to my 2016 Z and as much as I absolutely love the look of Brawlers, it is unbearable to ride, even with baffles. I felt like i was losing my hearing by the minute.

I've since refit my old akras but I really dont like the look of the big cans that are the akras, and would like something smaller.

Are the smaller can mufflers going to make that much difference compared to the brawlers? Or are they going to be quite similar?

Ideally I'd love not to fork out a thousand bucks just to be in the same place as I am with the brawlers. There's only so much you can get from youtube videos.

They are Delkevic 4-2 headers. I'm thinking I should have just bought their full system but I wasn't a huge fan of their mufflers.

The bike had stock headers and the akra mufflers when I bought it. I later bought a set of brawlers, purely for the fact I love the look of them. Going from the akras to the brawlers i noticed a change in tone but overall didn't really seem that much louder, or atleast hadn't hit the sound I like.

Later on I bought the Delkevics and fitted them with brawlers and it was just painful to be honest. I guess no amount of advice would have stopped me from giving it a crack though haha, but it was legit the loudest street bike I have ever heard. I like the throaty bark that it had but i would have gone deaf if I kept that configuration.

I ended up buying some db killers which made it go from absolutely intolerable to borderline tolerable. I've since put the akras back on just to preserve my hearing but I'm not much a fan of the look or the sound of these cans.

I'm hopeful that I don't need to decide between the stock or Delk headers just make it look the way I want.

Well, ive had twin exit arrows with brawlers on the end which as you say was deafening, even with the db killers...nice thing about the arrows is all the parts can be bought as individual parts - i was up in the air with the twin pipes so bought the single exit collector...then i had a stubby austin can, sc project bean can and then tried the akra from my rsv4 which was shortened by 100mm so not stubby but not full length....out of all the pipes ive had thats the best - loud when it needs to be and when not being caned quiet and at idle glugs quietly. Thats my 2 cents....

I went exactly the same route as you. Brawlers were OK with the standard headers but ridiculous when I fitted Black Widow headers.
The Akras sounded great with the new headers but they are too big and I hate the look of carbon fibre. A long hard search took me to Scorpion Red Power.
They sound great with the baffles in. One day I'll get round to trying them with them out.

I remember buying urban brawlers the first few months of ownership (after installing Arrow headers), and then immediately ebaying them off and getting Mivvs.. Weren't they (brawlers) basically straight pipes? Unless I am mixing up my memories or unless they made "improvements" after 2015. If it is indeed the straight pipe urban brawler, then it is safe to assume any short muffler with ACTUAL muffling properties will work out better than brawlers with after market headers.

That is a nice small can, is it substantially better than the brawlers? Hows the sound?

those austin and sc projects are up my alley in terms of looks, but bloody expensive over here in aus. What are your thoughts on those? I agree the akra checks those boxes but the look of them just isnt for me on this bike, atleast the cans ive got here.

Yep that is them, as straight thru as they come.

The bean cans are too loud - sc project and austin....as i say a 100mm shortened single akra is the best....(for me anyway) put it this way... mine consistantly gets through a uk MOT test with no advisory about noise (with a full system and no db killer in there) !!

How does it possible with full system?
Which is the high level of noise in UK?
With full system and Mivv Suono with dBkillers (omologated with stock exhaust tube system) I have 104-107 dB on 5000 RPM.
Max 101 dB legal (96+5 max).
I am now going to play with fuel map on Bazzaz maybe it possible to reduce noise with help of reducing Fuel during the test???

No idea what the noise level is in the UK - over here if the tester thinks its too loud (his discretion) then you either get a fail or an advisory...(advisory being "i think its a bit loud but ill let it slide...) - type thing.

In Russia you should go spent time and money to make legal a tunnig of exhaust, but nobody don't make it, because penalty is too funny low.

Even officer never issue the fine for it.

But mayor of Moscow seriously is going to increase penalty greatly for loud and unlegal exhaust.
Now there are debates in government.
