Anyone know where to get a yoshi from? I emailed them and they've said "The next batch of the 2021-22 MT-09 exhaust are scheduled to be getting made mid to late June (as long as our manufacturing department does not slow down)." I'd prefer the yoshi but am considering just getting the akra since I'll have it months before I can get a yoshi.
I got word from someone on Facebook that Yoshi told them over the phone that they are redesigning the header section so there will be delays. This was late last week

I think from the issues they had with the V1 version they are trying to change it in between the dozens of other bikes theyre working on.

I want the Yoshi bad but jeez we're going to be waiting until fall at least.

I can't do the stock system anymore Im just going to grab another system and change to Yoshi down the road
 
I must say Biohazard Cycles has phenomenal customer service and great prices. I had purchased a Akrapovic Carbon exhaust after quite a bit of emails and internal struggles of the looks (I prefer the low mounts). I wanted a Yoshimura AT2 as it has a nice deep sound, but people have been waiting months to get them. I then saw SC Project announced their new S1 Exhaust and I like the sound but love the look of the exhaust, what turned me away from them was the numerous accounts of non-existent customer service. Companies that make quality products and great customer support get my money.
 
Just wait. I have the 2021 Akra Racing Line. The bike runs a lot smoother with the stock pipe. The high flow pipe makes the fuelling grabby at very low throttle. Sounds lean. Hold out on exhaust changes until the ECU is cracked I reckon. Then get it tuned with a good exhaust.
Excellent answer, don't change exhaust UNLESS you're going to have it flashed at the same time. ECU IS CRACKED NOW. He is right, if you're not going to flash it, don't waste your money on exhaust, runs best with stock exhaust if not flashed. Very dead off bottom stock. I have an '18 with yosh r77 flashed by 2wheeldynoworks and it is FAST......right off the hit! So, I know how these bikes can run when you wake them up.
 
Austin racing exhaust available
Video on their website



I’m still keen on the spark exhaust system though
So disappointed that it’s a de-cat system. I know they do a lot of those but the demand on their social media comments for a full ti header system was huge. I’m definitely disappointed to say the least.

I have the M4 on my ‘21 SP and it’s great, but I only bought it to tide me over until me over until Austin released one.

Maybe I’ll consider the Yoshi again
 
I wonder what they changed. It looks like the middle might have a bit more of a kink in it now? Does anyone know? I had one preordered last year, but didn’t want to wait for it so I bought an M4. Then I was going to wait for the Austin but I don’t really want to hack up the factory header so it looks like the Yoshi might be back on the table.

I love the sound of the M4 and it doesn’t look bad but the Yoshi definitely looks nice with the AT2 can on it

yes. Me too!
I was certain that the Austin Racing was the one for me. But as I started to obsess over their systems for the previous gen, and seeing some comments on the forums, I realised that it is not a full system

looking at their release yesterday, I am also a bit disappointed that it is not a full system

I’m keen on the spark, but if the price is too high, then I may just get an arrow or Akra and be done with it

I did want a full ti from spark but if that is gonna be way much more in cost or take many more months, then I will just leave it

i can’t believe I missed this on vcyclenut’s page - thanks for pointing it out!!

i didn’t think Spark were ready to ship any exhausts!! Let alone have a full ti system ready to go out

that’s awesome

I’m gonna check with the district again on Monday when spark come back from holidays

I believe they've made some changes so the can doesn't scrape the ground on leans, saw some reports of that with the originals.
 
EDIT - found your dyno results here - thank you! They are the best I've seen :) 128hp and 73ft/lbs!

Hi Aleks

Thx for sharing the video of the dyno run of your Dominator - do you have a dyno chart of the performance that you can share? I've seen the chart that Vcyclenut posted with the mid-pipe muffler and I'm wondering if the exhaust without that is much the same?

I've had both the old and now the new design Yoshi AT2 exhausts. Yes, they added more of an angle on the midpipe section, changed up the brackets, the muffler has more of a tilt to it, the welds look much better, and they now weld the header crossover tubes. Has better clearance for lean angles and is overall a much better system now.
 
Hey guys, I'm struggling to decide which pipe to get out of yoshimura or carbon akraprovic pipe. I used to have an fz6r with a delkevic pipe on it and it was obnoxiously loud. I have tried to find people around me with those pipes so I can hear how loud they really are. So my question to you guys is, if you have heard both of them in person, is either of them 'too' loud?(I'll let too loud be to your digression) (Also I have looked at YT videos but they really don't give me a good idea of the overall volume of the pipes)
