Glad I watched this and read the comments! I have a full Arrow on my gen 1 but I was thinking about a black widow for my 2020 Katana, had no idea they had bad fitment and less than stock HP, bummer, they look nice and are reasonably priced.
I'd say this is totally different than what would happen on your Kat. But, a cat delete and slip on will make around 17 hp with a Sprint Air Filter and dyno tune.... But we're no longer in business at 57 Motorsports.
I do like the sound, not to loud. I like the look of the dual exhaust. I have a 2011 Hay Bus, 167hp before tune and only got 175 rear wheel horse power after tune. Im thinking hp should be around 170-175 base and it should be 180-185 after tune. It's pretty much all stock except for BMC filter, cat delete and Two Brothers Black dual exhaust. Any input would be appreciated. Just found your channel. Where are you located?
Hey Rad Rock... We're located in Tuscumbia AL. We've had bikes come from Chicago, Arkansas, and many of our surrounding states... As far as numbers go, I've never had a 2nd gen with just a cat delete on our dyno. The few we have done have had full 4-2-1 exhaust. This is where you'll end up with more horsepower at. But 8hp gains over baseline is pretty good. What brand is the cat delete if you don't mind me asking? I'd like to look into it.
@@radrock6249 so I went and looked that cat delete up.... It's designed exactly the same as this full exhaust is... That's what your problem is and why it's down on power. You suffered from the same issue we did in this video. We lost 8hp. You probably were down 8hp as well by the time it was all said and done.
@@TEAMWRIGHTEOUS if this is true then this power loss will have to be rectified. I guess i shot myself in the foot by cutting off the catalytic convertor. I will have to save my pennies and get a new header/mid pipe. I would really like to stay with dual exhaust.
Hey Chad hope you're good, wanna just ask you about my bike. I modded my stock hayabusa header to 4-2-1, i did a 60mm tube outlet in the end tube and 50mm in the secondary two tubes but i didn't modded the 4 primary tubes of the headers. for the exhaust it's an akrapovic carbone with a 55mm inlet. would this mod work good ? (btw i just did your external fuel filter mod and it works realy good thanks for your videos man)
Honestly... I couldn't tell you how it would work. Never seen anyone make their own header before using the stock header. But I'd be interested to see the results. And glad that video was able to help you. Makes it run so much better.
I have the Lextek header like that black widow...mine lost 6hp as well vs. stock....you are dead-on with your assessment... looks good and has a different sound, but is garbage for HP.
Yeah man.... People wonder why Brock's and a few other brands cost so much... Then you throw these things on and they show you exactly why. The stock header isn't a bad design at all. I think I could make this thing work if I had the capability of working with exhaust pipe to do what needs to be done.
@@TEAMWRIGHTEOUS I agree, I'm one of those people that like the look of dual exhaust on the busa...I searched for months trying to find dyno info on these black widow/lextek exhausts, I didn't find anything, so I became the guinea pig and tried it. Looks like they copied the stock design but screwed up with the H-pipe section. The header tubes are the same O.D. as stock but use thinner wall material, so it "should" have a little more flow, but the H-pipe section necks down....if I could do pipe work, I would make an X-pipe and let it eat. HMF big bird is the only worthwhile busa dual system as far as I know (if you can find one).
@@sc63sr20det yep... And that's why we made this video... Because someone is going to be where we were and wondering is it going to work. So now they can see, and hopefully the companies will make a change to fix the issue.
@@warrenprice2408 I'm learning it's all duals. There's not a dual exhaust on the market that doesn't lose power. The only reason to go with duals is for looks.
There wasn't really any weight reduction. We ended up leaving the stock header on the bike as it made more power. And then we built the motor and made even more power. Idk about fuel mileage... I know he rode it all over and never complained about it being worse. And he rode a couple of hours on a tank a few weeks ago, so I'm guessing he's getting 35-40ish maybe. Not sure when he filled up.
@@TEAMWRIGHTEOUS i have the gen 3 hayabusa and considering this since i want to get rid of the car and have dual slipons r77 oynx…otherwise the akrapovic full titanium is perfect
@@chinmayn73 if you want duals, stick with the stock header. It'll make more power than these. The most power will be made with a 4-2-1 quality exhaust.
What makes you believe you have 133hp? This is a totally different bike and made less hp due to the design, not just because we swapped exhaust. I think you would gain with a good full exhaust and a power commander is a waste of money. We can dyno tune your bike for a little more money than what a power commander cost and get you way more horsepower.
@@TEAMWRIGHTEOUS ive only googled the horse power for that bike and it says 133 but i dont know how accurate that is...i live in debary florida , so i would have to mail you the computer ?
@@silversorcerer9316 gotcha. So they're advertised as making 150 at the crank. And on the dyno they make about 120 to the wheel. That's completely stock. Once tuned, they're generally in the high 120s. I've seen one make 131hp with a slip on. Most of the time it takes a full exhaust and air filter, plus other mods to get into that range and higher.
@@silversorcerer9316 yeah... If you get the black Widow header, you can slip the muffler you have on it... As long as the piping is the same size. If you do that, we have a flash for it. You can contact me through Instagram. Links in the description.
160 Hp? What!! There's something seriously wrong with this busa! Stock, the Gen-1 Hayabusa makes 172 @9500 rpms from the factory. the 1999 model makes 175 with 138nm torque, with a top speed of 192 mph.
You're reading what the manufacturer rated hp is. And that's measured at the crank. A bone stock Gen 1 Hayabusa generally makes around 150-155hp at the wheel. There's driveline loss between the crank and wheel. Our dyno measures at the tire.
Yeah, the quality is actually really good... The fitment missed the mark for the right side slip on, but mainly it was just the loss in power that killed it for us.
Lol... For Hayabusa's, yes. I've heard good things about their 600/750 Headers. But really there's nothing else to compare it too since no one else makes them besides Yoshimura... Which gains torque and loses hp.

Never had any trouble fitting to a bandit.
thank you for the video from germany !
Have you tried the lextek header systems? They look to be better built and has a x pipe for better flow.
I have not
Obviously it sound different in person, but through my computer it sounds like it has a dead cylinder in it with the Black Widow on it...
It's the design in the exhaust. It makes it sound like two v-twin motors running side by side.
People said mine sounded like it had a dead cylinder on my bike on video. Maybe the dual exhaust sound
@@radrock6249 it depends on the design of the header and collector.
I heard the same thing.

Blackwidow are known for bad fitment bad quality here in Ireland hopefully there quality has improved a tad in recent years
