SOOOO much WORK - Thanks Chris!! BTW, just to be mentioned in the same sentence with Akro and Yosh is humbling.

Akra sounds and looks better, especially with how beautiful the welds are. Its amazing how they own their own foundries, the hydroforming process and the actual craftsmanship. I’ve been seeing alot of poor welds and exhaust leaks with the Pentacarbons as of recently

Akrapovic for the win!!!!!🤘🤘🤘

Dude I LOVED this vid. Really enjoyed how you went back and forth between the 2 bikes. I’d go with the akra, sounds nice but as I’m a daily commuter it wouldn’t send me deaf.

There is only one thing left to do. Take the samen bike with the same flash tune and switch the Brocks for a Akra.

That brocks with the flames hits different 😱💯

They all sound great, the Brock's is nice and shiny, the Yosh has the nice carbon fiber end cap, and the Akro brand is commonly acknowledged as having a quality build with excellent performance Guess it would ultimately come down to price (which wasn't mentioned?).

The Akro sounds very very good. I can imagine that exhaust wailing away here in the Arkansas Ozarks.

Brocks, all day, every day....for sound, power and definitely looks!!

I had my zx14 flashed by Ivans Performance. On his own personal zx 14 the akra made 10 more horsepower than the Brocks in the midrange. Both exhaust are good but for a fair comparison we need to see the akra bolted up to the red bike.

Akrapovic all day, everyday!

akro looks and sounds beautiful

Great test ! But With same tire, same filter, same wheelbase, You will be surprised what pipe will pull the bigger top speed . This was found with some ZX10 and hayabusa testing years ago. The brocks will show more horsepower but the Ackropovic will pull 2-4 more MPH on top, most people dont know this. I had both pipes on a hayabusa. Brocks looks better(Can wise) , and sounds great ! The Ti Ackropovic are a work (Header wise)of art ! Pick your poison that both great !

When you stalled the bike and looked back ...lmao priceless

Watching this video in Pennsylvania with snow on the ground and 24° temp. I see a good spot for me to move in for a month or two, right above that vortex sign. Just need room for my 14 and a cot, not concerned with noise.

I got gsxr bcuZ of this one (red) I’ll be seein you soon brother thank you for all your videos , brocks by the way for the win lol

There's too many variables for this to be a VS or even a comparison vid. Same bike same day I dont see there being much difference between the 2 exhaust. Both companies have countless hours into those systems to maximize performance. Would be nice to see this done on the same bike same day to show which one really is better.

Brocks has an old school look I feel. I think the akro looks more refined but the brocks looks more down home garage build drag race time

Great video but for the past 15 years usually the Brocks and Akro ran neck and neck give or take 1 to 5 hp either way, but the trick is Akro is lighter but cost more and thats the toss up

I like Akros sound more. Nothing against Brocks, but it's becoming the Wonder bread of the sportbike community.

BROCK for sure I have only bought Brock mods for my 2019zx14r extremely satisfied with the service

To truly compare exhaust, you really need to put them on the same bike, same ecu , gearing and tire combo as well as close to the same weather conditions. That's the only way to get an accurate comparison and to dyno tune each pipe not just throw it on which could be rich or lean etc. So that would take some time. The akro def sounds better and for sure and is a way better quality pipe, you can't compare that. Akro makes custom Moto Gp pipes and car exhaust. Pipe A really isn't a manufacturer, they don't have a ex building facility that I'm aware of. I would bet if you left the ecu alone and dyno tuned both ex suppliers top performing pipe that the Akro would beat it, then you could try a SC project, Arrow and I'm sure they would as well. Get some of those in and dyno test them for us KZfaqrs, we really want to see that. Thanks again Chris, you're bad azz

I like the looks and sound of the Apro better, this guy is obviously a Brock fan boy.

Brocks make a good looking product. I like all his full exhaust and his sidewinders are gorgeous.

Ak sounds perfect all the way thru the rev range.

I have my favorite full yoshi r77(no baffle), that said, I do like that sound and looks on that Akro. Air filter shootout would be cool. 👍😎

DW 170-190Hp is totally enough for drag-bike. Even if you have more power it would be hard to transfer it on the track with those tires.

Great video & work and time you put in, I have a GSXR 1000 and I have the akrapovic exhaust, I never had it on the dyno, but I like it, I like brocks to.

Ill tell you man your videos are exatly the shit im looking for on you tube for a month and a half I was torn between going with the akra,yosh, or brocks penta carbon I finally went with the penta carbon after seeing your 2020 1000... Then your video with the sounds of the different exhaust pops up and this one just strengthens my choice of going with the brocks penta carbon and the 185 sprint filter I cant wait for it to get here in april im litterally checking my email daily waiting for that email confirmation saying my order has been shipped ...great videos bro keep the GSXR videos coming

the exhaust someone gonna choose is depending the job he want to do, if you go 0-400 need brocks if you go roll race need akrapovic more speed

Dude….. absolutely no question. Brock’s all day. Sound is not comparable. The brocks sounds 10x meaner plus I’m an ohio guy so that makes it that much better lol looking at getting back into a Gsxr 1000 this spring hopefully. Brocks alien head with ur mooremafia flash 💯👍

That’s exactly what my 21 Zx14r sounds like when you let off the throttle. Brock’s is awesome.

Brocks sounds pretty amazing

I love akro exhaust. It's nice stuff

Arko sounds sweet... the Brocks exhaust sounds very deep and full. But great video! I need to link up with u to get my gixxer hooked up by u.

Just put a full alien on and man I couldn’t believe it.. can’t wait to get flashed and tuned

Both pipes sound great, but I prefer the deeper sound and throw back look of the brock's pipe. I ran a Bassani exhaust on my built GPZ , wiseco pistons yosh cams. Street racing, small time stuff. Im currently running a Two Brother's exhaust and juce box combo

But even with the fact the akra gsxr doesn't have a sprint it's still swb the brocks alien head gsxr has a small stretch on it so that in itself is robbing a little hp. I personally think the brocks, Moore mafia flash and sprint combo is just that good lol

Brock's exhaust, he's a good dude with excellent customer support also.

Akropovic Evolution WOW!

Evolution for sure that thing is sounding damn good with that qs

I like the sound and looks of the Akro but you can’t argue the performance of the Brocks

Maybe not the best comment...But i think Yoshimura has the most knowledge about exhausts. So i bet on Yoshimura - the one from SERT EWC 💣💯

Love the Akron sound but would love to see it with the flames post tune. Guess you can't have both 😢

Blocks sounds better and love the flames

Cant wait till I do some small mods on my bije so i can send my ECU to you. Love ur work and videos!

I’m stuck with that yoshi slip on from the factory for now ,,, but ,,, Brocks all the way !!! I’m switching to that full system! Brocks sounds and looks the best !!! Both akro and brocks performe awesome!

And clearly Brock's performance for the win I bet you it would sound epic even on a V-Twin big bore kit cammed predator 670

Thank you!👍Akropovic!) Wow look how smoth that power band is😊

Come on Chris.... that black 1000 was a slug out of the gate. Not a true comparison of pipe to pipe... gotta be done on the same bike. That said, the akro gained 10 before tuning on the black turd 1000 and that matches anything I’ve ever gained from any pipe, including Brocks CT Meg. That said, I run Brocks pipes on my stuff, but Akro evo is the Gold Standard for anything other then drag bike systems.

I would like to know the torque differences between those!

Brocks all the way ackro sounds smooth but the brocks is letting everyone one know I'm here

Brocks is killing it

Was that a Brock's slip on with a factory header? And how much do you charge to flash tune an ecu? My bike has a power commander 5 on it now. And I'm not impressed with it to be honest. I'm riding an 04 R1. Not sure if you can even tune it's ecu.

Apparently no one knows how akrapovic is spelled lol

Brocks all around! Akra is definitely top of class just can't afford lol

I like the brock but I would like to see what a racefit, m4, and a toce would make

I personally like the Brocks on looks also the M4 but, I like the shorty's. I just think those huge exhausts coming from under the bike look gaudy.

I have the alien head on a zx14 and I really like it. It definitely is a flame thrower. I had the Brock carbon fiber muffler before and then I switched to the alien head and put some zx10r wheels on it and it was a noticeable difference but I don't have any after h.p. numbers

Akropovic have on my 02 Gsxr-1000 still sounds and runs great 👍

Arko for me would love to know what the numbers on a full system m4 would be since it is like 500 cheaper than both ( quick shifter pop🥰)

I'm liking the Akro, nice job with the tunes

man that akro spit fire look nasty nice vid also ways Morre mafia for the W

Ackro. . . It baffles me how all these bikes & claims of making 200 & more hp . All the bikes & dynos I have seen you do have nvr seen you get over 182 hp from your pulls . What is your personal favorite of combos of 1000 ' s for flash & parts ? And is over 200 actual hp possible with flash tune & parts possible ! Thanks much for all your hard work & commitment to the sport !

When you comming to California to dyno here

Def, Brocks to my ears. When I buy mine Gsxr 750 2015-2018 cuz we dont have anymore new ones in Europe. I think what exhaust get and doing decat. Wish I could win Gsxr 1000 from your site but unfortunate my job situation in this summer is horrible lot of changes companys...

Akrapovic sound could be for daily drive but brocks sound for who want to so crazy 🤣🤙🏾both of them amazing sound and power 💥 💥 💥

akropovic for the win!

Suzuki had a deal going for a long time that if you buy a bike you get that slip on free, I think that’s why so many have it

AKRO SOUND BEST I LIKE TO SEE FIRE OR GRAVES IM RUNNING ON MY 2023 GSXR1000 FUN AS HELL PIPES STARTTING TO TURN PURPLE MATCHING FACTORY BLUE RIMS LOL LOL FAST AND FERIOUS

AKRAPOVIC looks and sounds better imo

I like the akra 🤤🤙

Akro all the way. I have one on my DL650. I usually run it with the baffle installed (quiet). Like to have it dyno tuned but they want nearly $500 at my local place.

My riding buddy had the ecu done by Brocks, full Hindle ceramic coated, stock air, chain and 93 gas with dyno and getting 188 at the wheel on his GSXR 1000. That’s pretty good I think. 👍 . He is very happy with the whole setup

AKRA FTW🤘

Yessirrrr I've got a 2011 zx10r with a full Akrapovic evolution system and it sounds and looks amazing, I've got the homologated shorty can on it but want to grab their racing can they make. Either that or a racefit exhaust 🤷‍♂️ I've wondered how a racefit exhaust would fair on the evolution headers and midpipe

Geeezzzz...advertisement for Brocks with skewed stats.....a Brocks full exhaust is no better than an Akro full exhaust and def not a 10hp difference..LMAO I had my 2015 s1000rr flashed and dyno tuned by Bren Tuning with just a yoshi slip on and a sprint filter and 4 pulls into it made 197hp and 97ftlbs torque. Bren said if I had a full exhaust on it I would have made another 3 to 4 hp. So enough with the BRocks is great shit! And the Yoshi slip on sounded just as good as the brocks and had all the pops.

I would have (and have got) akrapovic on my supercharged busa . Top spec quality , great dyno numbers (360 at wheel) and most importantly it goes through on the decibel testing (105 in UK) Brocks sound great but would not get through tech spec this side of the pond . Great video's , add 1 sub from England

Akro for me.

LOVE the content!! Question, why don’t you use the Yoshimura ALPHA T TITANIUM FULL EXHAUST? Is that not a good system? FYI you’ll be getting my bike this summer, I will be personally dropping it off from Cali 🙌🏾!! 💙

Great Vid !!!

BROCKS IS BEAST

Akrapovič sounds sweet, it's a toss up as the black GSXR was on 93 pump gas, GSXR with Brocks was using race fuel if i had to guess..

I love the akrapovic. And if I would send my ecu from Ireland could you flash it ? Is it then when you send back to my plug and play or I need do something like trothel lerning etc . Thank you so much

brocks alien head for me love the flames!!

“Brocks AlienHead II” for the win…

I wonder if stretched swing arm helps or hurts on the dyno, I know it helps put it down on the track but extra weight and distance seems like it would hurt on a dyno, albeit a tiny bit

Akro sounded amazing

Awesome. Keep them coming please! 👍

What fuel was in the red bike? And as far as looks and sound.... I love the look of the brocks, but the sound of the akra.

Like the akra sounds slick wit punch but i rock a brocks myself too

Chris, Anderz here from South Oz. Loving the flames and your footage. A question. I just bought a 2019 GSXR 750 with a slip in yoshi, after seeing this comparison, could you give me some recommendations on a full exhaust system, i want flames to toast marshmallows.

Would u recommend a shorter slip on for drag racing or long canister ? For an 02 750 . I’m debating on taking my hinde/Brock’s long can and getting an alienhead

akro all day long .

Great video

Akropovic for me. Nice video

both are great exhaust systems but after owning a brocks street meg and an acro exh, ill say the build quality is better on the acro but i did like the brocks sound.

Just had my ecu flashed on my 2020 gsxr1000r. Full akropovic exhaust. 198 hp.

Moore can you make some videos with slip on exhaust with ECU flash. GSXR OR ZX10R. just wondering how much HP if some bikes didn't get a Full system. thanks loved the videos

Did The Brocks had stock headers correct or was that full Brocks exhaust?
