"But officer, this is just the stock exhaust!"

[@Farlig69]

Cool job - a wee comment, the first layer or two of fabric around the hot pipe should be stainless steel wool to better tolerate the heat. Glass wool tends to burn out quite quickly so you will notice the sound getting louder fairly soon. It's okay for riveted mufflers where you can change the wadding very quickly but for a welded affair it's gonna be a pain in the arse to replace...

[@traskabraska]

top notch job. you're a legend

[@corjohn4]

This sounds awesome!!! Better than actual exhausts too! Wish you could do this for mine lol

[@michaelmitchell5909]

Bad ass man. Great job, nice work

[@ramonesteban5473]

Increíble trabajo , espectacular... Muchas gracias por el vídeo.

[@livingon2wheels]

I am shocked and amazed!

[@BBFazer]

Whoaw this impresses me. I'm going to buy a second hand exhaust for my tracer 7 to experiment in the same way you did. Thanks for the inspiration.

[@jackmcminn2520]

Pretty nice and sounds as good as the expensive ones

[@ivosilvestre9687]

Awesome! Thank you. can you please list the material that you used? like the diameter of the tube and angle tubes plz? Thx.

[@rexcarlyle5914]

Where did you get the piece of stainless steel piping?

[@RAYQUAZA_X]

You inspired me. I will not by akra axhaust right now. First ill try to do the same but with a smaller diameter tube and try to make a S shape with holes, not a straight large pipe like u did.

[@ar2043]

Genius!!! Thanks!!!

Thank you Luka 🙏

[@alexrice1451]

Much cheaper than a new system. Good job

[@haydendavid3248]

@Empty-07 I mean yes and no, expensive af gear but it looked like he just had that gear, now for the average joe, you can usually find someone with a welder or any of the grinder material stuff. (As for why he used a stick weld, I couldn’t tell ya)

[@sam_music555]

@@haydendavid3248 welder and grinder are probably the least problem, you buy once and forget. I wonder about vertical drill, and the ability to weld properly...

[@chrisfr3480]

Super boulot mais félicitations 👍🇫🇷

[@thewiredfox2691]

Maybe a bit late to ask, but do you know the lengths of the tube sections? I have a different idea and that info would be very useful.

[@nodwaa9227]

sneaky straight pipe :D

[@kulungshow]

AMAZING

[@HandicraftChannel-bj6nw]

hahaha amazing 👏

[@beno6687]

Can you do Yamaha R3/MT03 as well ? Ive been looking for R3/MT03 but I cant find one

[@googlelimp9834]

fair play mate not bad at all

[@Robocoppat]

I'm not easily impressed but this is the most impressive thing I've seen on KZbin regarding a MT-07. It sounds Awesome 👍😎. Consider me a subscriber.

[@vinceianni4026]

Hello AV good job well done

[@AVmake]

Thank you!

[@ojonfpv]

You're a genius

[@stekiboy]

Dobaaar!

[@alesandrocircu8919]

Hello what wadding do you use for it?

[@Bon-mz5kb]

Why do you need the cotton? And why make multiple holes in the inside pipe in the first place?

[@Cesar-jg8hm]

Mucho trabajo, para el sonido final,a seguir probando, yo ya he hecho varios,y mi consejo es que solo modifiques el tubo final de salida,es sonido será mucho más bonito

[@AlekR1]

I did the same thing on my exhaust, and got a great sound. But the engine lost a little power, is it necessary to remap after the exhaust modification?

[@erlcarmen]

Nice good sound

[@eatingelizabethsfrizbee]

Nice job.

[@cobe_nisam.radio.trrraku]

Hi mate! 🙋🏻‍♂️ Do you think this modification is possible also with the new generation od MT07 (2021+) where CAT is located in the pipes (and not in the exhaust chamber)? Thanks in advance! 🤙🏼

[@XatRingtone]

very good. I also have Honda CBR600RR motorcycles the sound is very loud. the police make a remark😜

[@MiguelCastillo-xm5iv]

just what i need

[@motoreli103]

Can you do this on Yamaha MT03?

[@gamesettings101]

Is it possible to let the catalytic converter on with the same result?

[@moonchild5364]

Questions! @2:55 is this stainless? @3:05 what is the material name he is holding? the curved short pipe.

[@Tortillo_Adventure]

Hi, wich dimensión for DB killer?

[@JAMM9713]

Alguien sabría decir las medidas de los tubos?

[@MT-THNDR207]

It probably costs more to do this whole operation than it does to get an aftermarket exhaust system.

[@Bon-mz5kb]

I dont think so. If u include cost for the machine and tools to do this, then maybe. But just the steel pipe, then it would cost very little. A full system cost over $1000 where I am from

[@vennemans9113]

Even if it does cost more which i doubt , having his own made exhaust is a lot more fun 👍

[@MT-THNDR207]

@@vennemans9113 That is true. An engaging project

[@lonescoota9542]

If you have got the tools I don’t think its expensive

[@MT-THNDR207]

@lonescoota9542 He literally had to buy all the packing, though.

[@sam_music555]

And What about emission checks? Would it pass an inspection?

[@NickParkerPhoto]

Can I mail you my stock exhaust to have this done?

[@Sinister_fartbox]

Yes go ahead.

[@CLS55-Fonz]

You'd be paying more than buying an aftermarket slip on

[@stardust6385]

Nice job, it looks stock but it's not. Please remove the db killer when you use the bike :)

[@AVmake]

Way to laud without it, I like it but others dont 🤣

[@arcadeshop8636]

Muy buen trabajo, lamentablemente el sonido no es el mismo escuchado desde youtube, presencialmente es otra cosa. Saludos desde mi país CHILE 🇨🇱

[@demon817]

This is a great idea, BUT for $130 or less you could have got a China exhaust, with all the labor does not make sense and you still have a ton of weight. A+ for effort.

[@bacano4400]

It makes sense for plAces where copa fine u for have customizations

[@Allen-Doe]

amazing 😍.. Can I do this to my honda Cb500x .. Bike is too silent 😢

[@secretagentrandybeans5298]

Trust me if you just get an aftermarket muffler it will be plenty loud

[@itachi_mj9924]

Well shit that sounds good 👍 🤔

[@copeland691]

what size piping did you use

[@copeland691]

also what is the spacing and size of the holes you drilled

[@thextraordinaregine]

wish this comment will get notice, i have a questions. 1. does the holes on the perforation part give it less power? 2. does the size of the chamber choke performance? thank you

[@traskabraska]

in general, to my knowledge, it might happen that if you "open" the exhaust you lose some power at low regime and gain some power at high regime. nothing a good map can't fix btw

[@cousinstu]

"Factory" 🤣

[@eumsm8185]

so pecou em não usar palha de aço n2 ao redor da flauta, antes da fibra de vidro, e depois da fibra de vidro podia encher mt mais com a lã de vidro, daria um som mais grave, menos estridente ....mas ficou um trampo legal, porem trabalhoso, e caso se arrependa, ou queira o som original, terá que arrumar um escape original, que é muito mais caro, do que se tivesse comprado logo um esportivo

[@jasonlawrence8302]

you can basicly get the same sound by just drilling some holes around the front outlet under the cover and it takes about 5-10 minutes LMAO!

Here in the Philippines we call it "kalkal pipe"

[@Sobrevivente762]

Ficou excelente, porém, bastava colocar um difusor é muito mais fácil e tem a probabilidade de obter 13 tipos de sons no único escapando, com abertura total em apenas 3 segundos. Teria o som original e + 13 sons diferentes.

Might as well start a company

[@iamvenk0]

I like the stock sound, very nice not worth in my opinion to buy akrapovic or something else.. 1. you going to have problems with police 2. you cant pass the motorcycle service if you dont have stock parts.

[@Lukas-px1sx]

Lol if you buy a original Akrapovic full system you will never have any problem w police or service bcs you have a homologation cards

[@iamvenk0]

True, but can you give me 1700 euro for a full system :)

[@Lukas-px1sx]

@@iamvenk0 In my county is about half of price :D

[@iamvenk0]

Good for you man. I like the stock sound, so for me there is no point paying 1700 euros for not almost but close sound. Because if i wanted the good sound i have to remove the db killer. Doing that i will have problems with police. This is what i sayd in the first comment. So yeah :)

[@Lukas-px1sx]

Исполнил, конечно классно, но такие "перделки" под окнами очень раздражают!!!

[@Reeds_World]

Sharing my experience, just finished this for my 2018 XSR700 1) This takes a lot of time and is a pain in the ass. Easily 8 hours in disassembly, drilling & prep - At least 6 hours tig welding the thing back together 2) I used a cheap AutoZone 2"-2.5" exhaust reducer - Summit 1" - 1.5" vibrant fitting - 1" bent pipe that was inside the exhaust & packed with HLX-160-1112 from Summit too 3) The jump at 2:08 is very deceiving, cutting the can in half on the outside is not terrible, maybe an hour. Then you will spend forever cutting out all of the seam welds, and you have to cut them all out or else the thing wont come apart. When you go to weld it back together I cut scrap stainless pieces to fill all the massive seam weld holes, there was like 8-10 patches. 4) Drill as many holes in your pipe as possible, I didn't have enough the first go around, it was unbelievably loud and sounded like dog water. So I had to cut it back open and drill more holes. Fortunately, cutting it open 2nd go around is very fast to weld back together, took maybe 20 min. 5) I left the header attached the whole time. I ended up cutting the top half off, unlike the bottom half in this video. Id probably recommend cutting the bottom out, sucks either way and there wont be much difference. To get the cat out I cut the 3" pipe holding it in down the top, pried it open, cut the pieces i pried off, leaving you with half a pipe, then pried away till i got it out, then cut the rest of that 3" pipe. Reason I did this in the first place is I've cut several other exhausts open on bikes I've owned, all can style though, like on my duke 390, crf450x, crf250x, klr650 and removed baffles. All of them were very easy and quick. This was a different beast. If you can cut and weld, you can do this, and id still recommend it.

[@nobbystyles4807]

whaaaat?? why would you go through all that nonsense of cutting it up and then welding it back together instead either doing a full decat of just putting a slip on on it? what a load of bollocks.

[@mbee1337]

by far too loud, that's just stupid loud, but nice try though
