2017 GSXR 1000 Exhaust Dyno Comparison Brock's Performance Alien Head vs Akropovic Evolution

[@BrockDavidson]

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

[@snootchie86]

You have one hell of a product my friend. The proof is in the pudding. I hope to invest in a full system one day. THE GAINS!!

[@mopar1465]

@@snootchie86 do it. You will not be disappointed whatsoever.

[@joejac07]

Brocks= the best. Had his exhaust on multiple bikes

[@klewis3530]

3 bikes. 3 Brocks full systems. Well worth it

[@gaddy8964]

Brock's c'mon now...you know your products are the reason why Akro and Yosh had to step their game up...lol And honestly, the other competitors are still trailing behind IMHO (especially street/drag). However, Akro has always been high quality while greatly improving their products since the dominance of your systems. And man do they cost a ton of $$$ more. I've always bought your exhaust/products since 2000's and will always continue to support you. 👍🏽✌🏾👊🏾

[@BigBro87]

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

[@Ldub556]

Akrapovic for the win!!!!!🤘🤘🤘

[@SirSpinalColumn]

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.

[@leonvanheerden8054]

That brocks with the flames hits different 😱💯

[@stevesmith6236]

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?).

[@erickvanes1285]

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

[@mikeparrish8976]

Exactly my thoughts as well.

[@oldschool6268]

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 !

[@BrockDavidson]

Test our CT series VS. The akro. Lighter, more power, better welds. They have a great pipe. We have a true performance pipe. What does it mean? Add our pipe and the bike runs like shit... Because it flows FARmore. Map it, and it all comes together. They would Never sell a pipe that wasn't OK without mapping. It would crush their rep... Who would make it work?

[@scottieray]

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

[@Hampus3313]

its akra-povic. Not akro-povic.

[@DeYanko]

Akrapovic all day, everyday!

[@mmorgz6622]

akro looks and sounds beautiful

[@greglynn49]

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.

[@tysta2]

Yap akrapovic it's going to make more numbers always. Only fake stuff just to full people.

[@randyheiser5367]

Ivan's does impressive work.

[@mopar1465]

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.

[@Glee1k]

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

[@bvailes775]

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

[@F_B-sh1cl]

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

[@jeremyeubanks2387]

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

[@meltingpotracing]

That man done stalled on the dyno 😭😂

[@stevelubosco7286]

8:05 stall. Bikes nasty. Awesome videos.

[@robertgoffjr2450]

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.

[@alexrendon5484]

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

[@RyanScharf]

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 💯👍

[@EnviedKing]

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.

[@Evan-nl2hg]

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

[@cameronbaker6115]

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

[@maddbadman4932]

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

[@James-jy2lg]

Ak sounds perfect all the way thru the rev range.

[@chriswade3986]

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

[@jeremyeubanks2387]

I love akro exhaust. It's nice stuff

[@docmoto6477]

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. 👍😎

[@KillSpawn47]

Doc Moto yes definitely would of been good to hear a full yoshi instead of a slip on

[@rharkless5]

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.

[@owl1873]

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

[@erickholm9563]

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

[@Nsimy1]

Akropovic for me. Nice video

[@Ldub556]

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

[@reinhardbredenkamp3618]

Akropovic Evolution WOW!

[@mopar1465]

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

[@ericadelgado8250]

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

[@cryptoairdata4417]

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

[@robbeck3316]

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

[@w.stanford5662]

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

[@MrDamient5]

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

[@reggier2343]

Brocks is killing it

[@haydengrant1796]

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

[@beckers1330]

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

[@ballintundra10]

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.

[@antonioneblett7181]

Brock’s definitely sounds the best

[@llerradish]

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

[@jerryjones297]

I would like to know the torque differences between those!

[@adult1122]

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

[@saadalsaad2914]

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

[@Popsm0ke]

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

[@darthgixxer5451]

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!

[@DavidKuszaj]

Brocks sounds pretty amazing

[@123goonme]

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

[@MajorPerformance101]

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

[@sickadigeup9053]

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

[@chadtucker2875]

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.

[@TeamMooreMafia]

I can not do the ecu on 04 r1. I actually have a video coming out Sunday with an 04 R1 in it! You need to have yours dyno tuned. I charge $200 with power commander

[@bacchusthompson5834]

@ Chad Tucker... You can send your ECU to ECUnleashed, they will be able to flash it. Then you can have Mr. Moore fine tune through the PCV. The real set back is you can't adjust the timing without an Ignition Module from PC. ECUnleashed will adjust the timing when they Flash it but, it won't be dialed in like it would if Mr. Moore was doing it on the Dyno. Honestly, best scenario would be to purchase a Ignition Module through Moore Mafia and have him completely tune it... Not a sales pitch, just makes the most logical sense.

[@nimeshvala1793]

2:51 cilencer price?

[@cocosloan3748]

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.

[@perrihoward4673]

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

[@1pipepro]

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

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...

[@samholcombe3129]

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

[@NoControI]

hurts dyno more chain more rotating mass.

[@hussienhassen1997]

Which one the best sound?

[@robl1417]

Does the O2 sensor blowing out the pipe change the readings? 47 second mark.

[@cali8221]

What is better for power brocks or akrapovic?

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

[@antoinegauthier7027]

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 would have (and have got) akrapovic on my supercharged busa .

Great video's , add 1 sub from England

[@peterherrington3300]

@@300zxdriver 2 chargers available (that I know of). Procharge and rotrex. 230 ish horsepower options right up to 500 plus for full drag use. Substantial upgrades required obviously , forged rods , pistons, base spacer to lower compression , lockup clutch to start with . Not a cheap option but plenty of power and over 200 foot pounds of torque from 5 thousand (without any lag ) makes for huge grins and mid 8 quarters .

Or better yet can you just bring your dyno with you to XDA at maryland international raceway 😂

[@markday2198]

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 !

[@b0xhead96]

Bit of a late reply but manufacturers power claims all come from measuring power at the output shaft in perfectly prepared and monitored lab conditions rather than at the wheel. Dynos measure wheel horsepower which will always be around 15% lower than the actual engine output but even then, no two dynos will give identical results.

[@pcs38nau]

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.
