back pressure. the way you explained the pipe example, even my college was struggling to teach that!
Bro if in the case of carbaretor engine wht should i doto change ma stock exhaust putting the after market one instead
@@vishnunarayanan4906 up should tune the carb increase the fuel.liitlr bit according to the need of ur bike
I’d like to thank you for a straight to the point answer, instead of something hidden in the middle of some 20 minute video. I learned a lot from your video and will be able to decide on my exhaust mods accordingly. Thank you again!
Thanks for watching mate. Hope you enjoy my other videos too and hope you subscribe.
Your all videos are really helpful. Best motovlogger of India for sure :)
Still to this day , you are the most informative moto vlogger in India. Thankyou sir for your work
Thank you for the support brother 😊
I recently bought an Apache RR 310 and that's when I started to learn about exhausts after about 15 years of riding motorcycle (a Pulsar 180 DTSi UG-1 and a Hero Honda Karizma R, to be exact), because, you know, I'd love to have a better, lower-tone growling sound coming out from a bike like this model of Apache. Searched and viewed many explanations and videos and quite frankly, this particular video of yours is the best for me to understand why or how or which part i'd consider changing in the exhaust system of a motorcycle.
Good job, man. You've got a new subscriber.
I watched this video in 1.5 speed 😂😂
Hope i would have looked ur comment before wasted a lot of time
I always listen to YT at 1.5. But Indian accent I just can't understand half of it.. 1.25 is good lol
This is one thing I really like about your videos... The technical aspect which is not covered by majority of moto vloggers in India..!
Well explained principles... Keep up the good work..! 👌
vikas deserves more subscribers....
thanx
vikas buddy for like my comment
Thank you for the explanation in detail. Now all my doubts and confusions are crystal clear. Hats off man. U r a Guruji for the motobikers😎
Damn bro. I'm in my tenth grade and I actually understood each word. ❣️ You're a genius
Sir thank you for clearing the most doubtful topic which every biker has about aftermarket exhausts
Are first copy exhaust recommended ?
If not, then why ?
I have a ninja 1000.
Yes but you will need very good quality
Don't have more horse power just have a good sound. thanks for the video Sir..
Beautifully explained sir......BUDDIES...thank you sir 🙂❤️
You are a man with true motorcycle knowledge!!! Love your explanation
Seeing R1 after a long time. #AGELESSBEAUTY
None had explained it so easily Tqsm Bro
Older bikes that do not have the ECU you have to re-jet and adjust the air. Nice job explaining what happens.
something easy to set, yes :) tune the carburetor. +1 for older motorcycles for this example.
nice topic to share...only one tip to u bro...if u have full system exhaust then u need a powercomander which is quite expensive to buy !!slip on are better but slip on a z900 is useless to spend 55 k which sounds like exact same as stock due to the presence of cat box in collector
What if I just use a slip on?
What if Underbelly exhuast like in case of my 200ns, the exahust pipe is small and projects out of the collector , what can we do in that case?
Ya bro what can we do in ns 200, rc 200 ,duke 200
Headers need to change
@@user-xe7nk7jq5e i can't understand bro
Great informative video
Thank bro
Helpful boss
no one could have put it in better words. simplest explanation about the exhaust function and its various parts that i have ever heard. great going. all the best!
I almost clicked on to the next video when the video started but I'm glad I watched the entire video.
Awaiting so long for ur vlog Bhai 😍😍✌ Bhai kindly review Ns200 abs it's my tiny Humble req
Useful stuff brother 👌 and can you explain about a normal spark plug and iridium spark plug.. thank you
Brilliantly explained Vikas, will be sharing this video to everyone who thinks about going free flow with only exhaust sound in mind.
finally I found someone who can explain to me. well done sir
Vikas sir...your videos are always informative but back pressure is the most misunderstood term in exhaust system. However back pressure is the negative pressure wave created inside the exhaust pipe ..this wave is just behind the positive pressure wave generated after each exhaust stroke...and yes restrictions in exhaust causes obstruction in the flow but back pressure is not the right term for it. Back pressure helps scavenge out the gases by creating a negative pressure zone inside the exhaust....and when it comes to straight pipe free flow exhaust...they are good but if engine is not tuned accordingly then it reduces fuel efficiency..causes lots of unburnt hydrocarbons and afterburing of fuel in exhaust.
Lol u didnt got a like from him
Fayaz u r right. Free flow exhaust let's mileage down because the charge is not fully combusted and escapes the cylinder as there are no restrictions in free flow exhaust.
How is your Dad?? I hope he is fine.
Btw bro, in a video you told that your Micron exhaust has fell somewhere on the road. Did you bought another one??
Abhishek Mohapatra Good question bro, only the end cap fell off, so, I got it fabricated... Cheers
Thanks Vikas for replying.
Vikas Rachamalla Please please make a review video of your R1. I love your R1
Due to this SLOW, CLEAR, and WELL explanation... 👍👍👍👍
I become a new subscriber of your channel bro.
Keep it up. 🙏🙏🙏
Very well explained. This is what I expect from a technical moto vlogger. To explain each and every part like a professor.
Nice information bro tnx
Wat abt a carburetted engine? Wat shall be done in a carburettor in case of a full exhaust system installation?
Rejet the carburetor
I own single cylinder motorcycle , so I've changed only the muffler , The pipe from the header to the muffler is the stock one , I dono whether it has got connected an all !. So will my engine get damaged ?
Akib Basheer nope your engine will not get damaged don't worry✌️
Jets must be altered
I hope n wish that Vikas would n should make a video on the changes or upgrades to be done on a carburettor for its compatibility with the after market exhaust system, if one installed. For the best performance...
Very helpful . I have been seeing many videos about this matter but so far no one has given right information . Thank you so much
Thank you, very well explained.
The question of horsepower gain, and keeping performance (increase in speed without affecting much of fuel economy) was confusing me.
I’m happy I found your video which was very insightful for me to make the desired result and decision.
Finally someone talking English 🎉🎉🎉 productive info
When are you getting the suzuki back from your mentors place?
wonderfully explained.. you are our automobile teacher.. who explains explains big things in a nutshell.. thankyu..sir..
So much more than one year I have an dobut about changing after market in bike in 7.00 mins dobut has been cleaned thank u vikas bhai
And one thing you're helping me so much for making my video content clear by seeing you're review (not copying just clearing dobuts) 😂😂
My aftermarket exhaust didn't harm my engine for 20000km and it's still running smooth with proper service
VetRi Vel which exhaust and what is ur bike?
Rishi's Studio gixxer with a custom built exhaust
150cc???
VetRi Vel can u please name the exhuast you used on gixxer i am willing to buy a new exhuast for my gixxer
@@khushaltiwary217 i m w8ing too dear i think akvapolic is best
Bro u have much more idea about motorcycle..i loved your explanation 😍😍😘
I'm from tamilnadu...Explaining in english is easier to gain knowledge for biker 's.....Thank you Uncle.
Thanks for watching. Hope you enjoy my other videos too and hope you subscribe
The best thing about your video is the way you explain 😃😃😃
Buddies!!!
Hey did you renovate your house?
Yes bro, I made a dedicated parking for the bikes :) Cheers!
Finally I got a decent answer about that. thank you sir!
Watching your videos are allways full with knowledge u jst clear my doubt .
Why don't u make vlogs on GSXR 1000 ?
Thanks for asking bro. I am missing riding her, she is running very rich and I need to fix the fuel injection issue. Hoping to do so soon.
Vikas Rachamalla sir I have install akrapovic buyed from Ali express I hv install it in my r15 v.20 I HV cut the pipe from mid... And make new bend pipe from mid to exhaust.... Sir plz rpy me.. M very m worry about this
Good evening Vikas Bhai, how is your dad?
Best Motorcycle knowledge Indian channel on TH-cam. Thumbs up bro
One video that i found much useful in the past years...hats off..worth spending time

.......nice 😂
Bro u should have been my teacher.tht example of back pressure is just amazing.
Thank you, your explanation is the most comprehensive and detailed I have ever heard, you explained everything perfectly. Take care. Mike.
Thanks very much!
The best explanation I ve heard so far .. thank you sir !!
Thanks very much.
You are like a teacher a gud teacher i understand from start to end👍😊
Explained in a very nice polite and humble way
Today I learnt something new from you bro. Thanks a lot for the explanation mate.
I never understand about the back presure work on exhaust until you explaned with the example of the water hose..thanks!!!
Thanks for watching mate. Hope you enjoy my other videos too and hope you subscribe.
Finally speaking english in vlog. Thankyou
Your videos i love because they are so informative and easy to understand,... Thank you sir ☺️
Technical videos are your channels charm sirji..
Thank you so much, I have karizma R, and I have modified it to dirt bike not purely but it's looks like dirt bike, I removed the stock exhaust and put the Leo vince exhaust after that backfire start up... So thank you now I can stop backfire from my bike thank alot
Cool video I just bought a slip on muffler for my Versys 300x. It sounds very good.
I learned everything I need to know about my exhaust system from this video. thank you
Excellent explanation!. The best on TH-cam to my knowledge about this subject. Suscribed!.
Thank you very much 😊
This is the best video I have seen on this matter. Thank you.
Thanks sir .. Now I can buy muffler without any doubt ... 🙂🙂.. love and respect from West Bengal 🙏
Man how are Indians so good at explaining stuff!! 👍🏼 Thanks bro
sir your video helps me to understand about exhaust much better... thank you..
do well sir..
Very well said. I wasn't going to click this at first because I thought it would be another hindi review(which i don't understand) but surprisingly, i was impressed and honestly not expecting it to be this detailed. Good job and please continue to create educational content like this. Thumbs up from Philippines 👍- your new subscriber 🔥
Thanks very much!
Your all vedios are so helpful for those who interested in bikes like me. Thank you brother
The simplest and perfect answer 👌. Only replacing muffler does it will affect performance.
bro...thanks....actually I just changed the muffler of my ninja 250r and bit worried...but this video make me sleep peace fully....
I own a z1000.. Your explanation has been very helpful as i nearly wanted to change my Yoshimura R77 exhaust and I realised i don't need to...
Thanks a lot ... This is good information... I'm a mechanical engg student.... Helps alot
Hi Vikas Bhai
Very informative video explained in easy way and detailed abt the pros and cons
u again proved! quality matters! new member of ur channel🖤
Namaste! Greetings from Bajaj D400 user from the Philippines.
Cheers brother
explained in very simple and organised manner i got clearcut view after ur vlog need more videos from your side

Wish I had a friend like vikas
+Vikas Rachamalla, Sir you have forgot to mention O2 sensor on the header pipe and after catalyst. It is a vital data; if a bike has a O2 sensor on the exhaust (which is Closed circuit fuel control system); a remap is certainly required without any further thought. But if a bike doesn't have a O2 sensor and controlled by Capacitor/Transistor based ECU (which is a open circuit fuel control system) it controls the motor based on throttle position, MAF, engine speed, gear position, fuel pressure and engine temperature an ECU remap is not compulsary and it will never control the AFR based on exhaust pressure or back pressure. (NOTE: Exhaust pressure is calculated-recorded-controlled in externally charged engines)
I believe, If the exhaust of a bike, without O2 sensor, is replaced with free flow exhaust it need just more air to breathe, so a performance free flowing airfilter is needed and certainly in that case one need a fully mappable ECU, that will ensure the correct working of MAF sensor and thus AFR will be controlled.
Theoretically, free flow exhaust can reduces the pumping losses, because there no restriction in gas flow. Exhaust pressure is only vital and should be maintained to ensure the conversion of CO completly! 3 way catalytic converter requires right temperature, pressure and velocity to do its job. If the catalyst is removed there is no necessity of maintaining the exhaust pressure.
And the example you gave for the back pressure is irrelevant! Water is an incompressible fluid whereas gas is completely compressible. Back pressure is a pressure wave created due to the change in exhaust pipe diameter/shape which does changes the flow velocity but it will not burn the valve; (NOTE: 2 stroke engines a expansion chamber is installed to create pressure wave purposely that will increases the charactestics of the gas flow as it doesn't have a exhaust valve)
Valve burning can be caused by various reasons but the major of them are valve seal wear, improper engine cooling, carbon deposits (hot spots), improper alloy used in valve. But back pressure ain't one of them!
A vehicle with 2-step launch system as well as anti-lag system can burn a valve that is only made for low speed applications.
Wow, thanks my friend.
Rohith Ramachandran o2 sensor automatically adjusts the air fuel ratio on a bike. Afr means air fuel ratio.
P.R. Hariharan
There is a phenomenon called valve slam which occurs when the engine runs at high rpm under inadequate back pressure, which will damage the valves.
Vikas Rachamalla 1) Whats the difference between Exhaust, muffler & slip-on..??
2) What is db killer??
3) what is meant by a free flow exhaust? and does this contain catalytic converter..??
Prajeesh Premachandran Sir, I have never heard of the term 'Valve slam'. There should not be back pressure in an exhaust system at any higher rpms. Because the engine will run richer, if the back pressure wave is higher; exhaust gas traps inside the cylinder due to reduced flow velocity, which is a good thing interms of emission reduction but It will affect the volumetric efficiency severely. Some engines are designed and developed to do scavenging at higher rpms! If more back pressure is there in the system; more exhaust will be trapped inside the cylinder and air density will get affected, engine won't produce high end torque!
By the term 'Valve slam', I can imagine one scenario, improper valve timing in large cam profile, in general, exhaust valve opens gradually from 20° (or may be even higher) before TDC and continues to open till the piston reaches the valve clearance area on top of the piston and then inlet port opens simultaneously; to do the scavenging process and the exhaust valve closes after 5° - 10° after TDC. If the timing is mismatched, there is a chance of catastrophic event such as piston hitting the exhasut as well as inlet valve and the valve bends, which it can be termed as 'valve slam'!
I kindly request you to share some links for research paper on 'Valve slam'. My humble request.
I appreciate your efforts to provide such quality information. Thanks
Rachamalla racha, straight shooter with crisp clarity.
Thanks brother!
This is so helpful. Easy way of explaining.
The best and most simple explanation ever vikas anna...love ur videos.
Easy way to understand it. THANKS!!!
correct explanation coz i have already experience a free air flow of modified motor 200 2 stroke exhaust engine, it gives me much power in the 200 meters straight race but damage in a long normal run of 40 kls it really create too much heat and burn the valve system it only good for short range distance race with time duration in order to avoid overheat but it really run so fast with the same engine specification.
Your explanation is superb sir
this video solve my problem
Thank you.... you just explained it in a very simple way.....got it now
Brilliantly explained and understanding
Thank you for the detailed video. Helped with my question.
Vikas Sir is the BEST ❤️🙏
simple and clear explanation thanks vikas
thank you sir..the BEST explanation without any bullshitting around.subscribed.
Really sir you have answer for my every present query in the form of video that too years ago😮.
Thank you brother.
You deserve more subscribers,you nailed it,explained it in a simple words with full knowledge. Please do videos like myth buster, looking forward for alloy vs spoke wheels.
Thank you brother, I will.
it depends , if you have from the factory an wide band o2 sensor and the computer has autotuning function , then it will correct for the new exhaust , even some engines with no wide band o2 sensor computer does some corrections because it is designed to run at sea level and also at 3000 km altitude sow it needs to have some correction capabilities , but I repeat not all computers do this you have to check this for your own , and an important thing is to maintain the approx. original temp at witch the o2 sensor was designed to run that is important for all engines !
Very informative. Very easily explained. I am planning to change only the muffler of my Dominar. Thanx for thus video. 👌
Very neat and cleanly explained everything 👍👍👍👍👍
