I realized long ago, anything proclaiming to be "universal fit" only meant it didn't fit anything in the known universe. Love your channel, good work !!

[@clutchpedalreturnsprg7710]

dxD

[@geofferydeanjackson9244]

Yeah I get a lot of salesman at my place of employment an embolism whenever I complain about "Universal" parts. They fit nothing universally. Get the specific fit parts for whatever you are working on. Doesn't matter if it's a brand new RE Continental or a lawnmower.

[@hendetta]

New owner of 2023 Conti GT650 and so glad I found this channel. Subbed so plz keep em coming!

[@michellefriend8848]

Having S&S slip-ons installed on my RE 650 INT. I’m relived to get your endorsement of this set up since it’s “all Greek to me” as of now. Watching your KZbin channel is very educational because IMO your both are very good teachers. Thank you from way over here in California USA.

[@utkarshchaudhary189]

Hey guys! I own a 2019 Royal Enfield Continental GT 650. I have a thing for making minor mods on my motorcycle after doing a thorough research. It was during one of those researches when I stumbled upon your video about the air filter system. And, I'm so glad it happened! Why? Well, there is a plethora of content available for almost everything technical about motorcycles. But finding you guys sharing knowledge keeping the 650 Twins as the foundation was really exciting for me! Your videos not just helped me understand the working of various motorcycle systems in general but also made me know my GT 650 in a better way. I really like your content, the way you guys explain things in detail using actual parts and not just animations, the whole stepwise process, and your suggestions. Again, I am so glad I found your channel! Keep making such videos, cheers!

[@RevelryCycles]

Welcome to the channel!

[@ark1289]

This is the most detailed explanation for exhausts I've seen and that's not even the best part of this video. You guys make this so interesting. I subscribed

[@ThrottleDownunder]

You both are naturals on camera. Congrats on 100 subs. And thanks for the mention.

[@stanislaviv14]

Bless you guys. That was exactly what doctor ordered

[@psy-boparadox3416]

I got extensive understanding of exhaust system from this video. One of the best explanations of WTH exhaust system do. Great job!

[@RevelryCycles]

Awesome, thank you!

[@SeaYaSailing]

and another RE twin channel............right up my alley.............2019 RE INT650 Baker Express owner...........love this bike. Much love from Las Vegas. Keep up the great channel, because this is what i want to do to mine

[@ProducerBoy650]

Bought the S&S and DNA filter as a result of watching your video. I was not disappointed! Thank you so much for your videos!

[@adrianpeds]

Is your bike a 2021 model? Has the euro5 tuning done anything weird to the bike after the installation?

[@ProducerBoy650]

@@adrianpeds it is a 2021. The bike calibrated to the change the first time I tried. Been running great ever since.

[@rvdvogt]

I used to own a (1970) 750 Interceptor Stage II in the 1970's and still regret selling it. It was upgraded with an alloy clutch and a Marzocchi front with twin discs. Lovely bike. At the moment I have a 2010 Triumph Speed Triple but the new Interceptor is an option; specially with the 865cc kit.

[@MrKdr500]

I made my own 1 3/4" (with a balance pipe) headers with AEW reverse cone mufflers, DNA airfilter, NGK plug caps, removed PAIR valves and powertronics fuel controller....51.6 BHP at wheel and a very responsive engine now.

[@TonMachielsen]

What a nice compliment. Thank you Dhruv

[@harshreddy2451]

What a genuine explanation about the science of exhausts. loved it and subscribed!:) pls keep making more videos. Love from the India:)

[@iangriff50]

At last a KZbin channel that tells how it works and what happens when thinks are changed/modded. Great video keep them coming. All the best from Oxfordshire🇬🇧👍

[@deepakdebatirtha]

Thank you Santina and Will for the detailed description. I do own S&S and I did a lot of research before buying it. I did installed on my own after watching videos but honestly no-one talked about the gasket. I consulted S&S and got it clarified. I appreciate your time in explaining in detail installation of S&S pipes. Great stuff. Cheers 👍

[@mattgoodmangoodmanlawnmowi2454]

Hitchcock’s in the UK has a video about using a new gasket to match the 865cc cylinder diameter Though this tuning series appears to be more comprehensive and in-depth. Damn I want a tuned Interceptor. !

[@SimarjeetSinghh]

5 minutes into the video and i can already feel that it is well made informative video, glad i found your channel 🥂

[@paulnosek714]

Great Video and great team at RE Sydney

[@adifyi]

Fantastic video, in all my years I've only seen videos of people reviewing what third-party exhausts sound like and the perceived difference it makes to the overall ride quality. This is quite enlightening :)

[@batman97]

This Video was a very informative one, I liked that. Glad I didn't already buy a set of slip-on for my Continental 650 and thank you for manufacturing a header pipe that will match the S&S slip-ons. I am definitely looking forward to buying the complete set as soon as my warranty ends or maybe sooner. Also please do a video on Ohlins front and back for the bike. Cheers.

[@G58]

Wow! You deserve my sub just for chopping up that standard system and revealing why it’s So Nasty! 5.3kg? That’s insane. A decent replacement stainless 2 into 1 system could easily save 10kg on that bike. Now I’m going to watch the rest of the vid. Thank you both for sharing your findings. Your approach is perfect. You’re combining the perfect level of personal, solid advice and corporate offerings. You literally broke the mould. Ride safe

[@jeremycrowley3075]

Think you need to check your arithmetic, unless the front pipes are made out of lead .

[@G58]

The use of the cut away view of the exhaust is genius. I was thinking 'what is in this thing?'......now I know

[@jcchico902]

Loved the video.....have 330 miles now on my interceptor, I am completely in love with this bike.....have been looking at the myriad of exhaust videos, and yours told me all I needed to know, thank you.....am going to check with my dealer first about headers, they have been phenomenal to deal with ( knocked $750 off the price and threw in first service for free). So I prefer to stay loyal to them. If there is not a suitable local source I will definitely give you a shout!

[@Franky644]

Excellent content and very informative. I would have loved to listen to the difference between the 'Street legal' and the 'Race' exhaust though!

Great video in a relatively untalkedabout topic for these great bikes. Great video, keep up the work You guys should also consider doing a motorcycle give away that all the big motorcycle themed channels are doing.

[@Soshi12005]

If would be cool if you do some maintenance/repair related videos, videos on custom bikes like the scrambler from before and maybe some long term review videos on the RE bikes since you can review them longer than the average press journalist boring ‘first ride’ review. Keep up the good work. I’m a potential rider from Sydney Australia as well and I love these videos

[@manormouse1410]

Superbly presented. Very informative. Thanks. I haven`t yet bought my RE but it has become my new obsession. One question: Which after market cans tuck in the most? ie; don`t protrude so far out.

[@Hchkrdtn123]

One word! SUPER!!!

[@MacnaMack]

Great vid. O'm glad I stumbled upon your channel. Liked and subed. Pls share the link to order the S&S with your open pipe.

[@jasonrichardwatts]

Legends! Gotta drop in to see your shop.

[@onecrazywheel]

I just purchased a set of Red Rooster stainless steel exhaust slip-ons off eBay the other day for $300 new. I've seen and heard a lot of good things with that exhaust too. Hoping I made a good choice. They should be mailed out soon from India. Great video. S&S would have been great but very expensive. God bless 🙏 Jeff - Sunny Central Florida 🌴 ☀️

[@Markdoria]

Subscribed! What was the small universal slip-on you installed and is it sold as a kit to make the install go as easy as you made it look? Is it loud, dont want super loud if thats the case. Thank you

[@pikebobstar2033]

Interesting and informative video 👍 I have fitted Scorpion silencers to my 650 but not convinced it suits the bike. I previously used a Norton style peashooter pipe which suite the bike but was too loud. Now going back to the peashooter as have now managed to find suitable baffles. The heatsheild is a must to hide that ugly join. I an fortunate to also have a classic chrome 500 too. Just love the RE brand. Look forward to more videos.

[@robertpinder2307]

You guys do a great job, I have learned so much. I know it's unusual but I would like my 2022 int to be quieter! I have the S&S slip ons and they're nice and light but they're too loud even with the db reducers in place. I don't know how much louder than stock the S&S's are as my dealer installed before I picked it up. Is there such a thing? Can I stuff the S&S's with some sort of packing? Any advice would be appreciated. The world is a noisy place!

[@brookcampbell2940]

I have the Continental GT 650 with S&S Race only cans and Cam. I have delayed doing the big bore kit because no one makes a set of headers to allow better flow. You guys hit a home run! Even thought of adding bungs for tuning. I hope you ship to the US

[@RevelryCycles]

We do ship to the US. Send an email with your postal address and we’ll get you a quote for freight [e-mail]

[@brookcampbell2940]

I have these on my bike now. Worth every penny, and the sound is sharper-deeper-louder. I did notice when removing the stock header that about a 1/3 of the exhaust port is solid aluminum. Can't want to have that ported out with the 865 kit.

[@charleslowreyjr.6355]

@@brookcampbell2940 Hey Brook, just checking to see approx how much it was to send those header pipes to the US, and in what State please. Also do you still have them on the 650?

[@garudamachina]

One of the best videos, informative and well well made. Thanks a lot! sub for life

[@wfdTamar]

Love that you're willing to share info that others may think would harm their business (I mean showing us how to DIY). I reckon in a lot of cases it shows DIY'ers where their limits are and that if you want it done properly get the shop to do it. Would like to hear the difference the various exhaust options over stock. I presume the headers you make are single wall and so will discolour? (seen on the site they're race only anyway).

[@amit28jha]

Very informative content. I would really like to see more videos. Please include the exhaust sound also.

[@ersriv]

Congratulations, I love your videos, if I tell you sincerely that this video missed you trying the different sounds of the exhausts, your explanations of the topics covered are very good and I would have loved to work with you, they are great, a great greeting from Chile

Great job. One question, I am not looking for awesomely improved performance but looking to significantly reduce the weight of my bike. Head pipes and mufflers seem to be a good way to start. How much weight can I gain with new head pipes and S&S mufflers ?

[@pacodawg9879]

I’m picking up a INT 650 on Tuesday, so I would definitely like to get in touch with you about one of your full systems. I literally just found your channel when I typed in “Royal Enfield INT650 Exhaust”, so any info you can give me will be greatly appreciated.

[@f33fifofum]

This was really informative on the principles behind exhaust system design, great video

[@prashantpatel4203]

Amazing gt stock exhaust comparison sir 👌 im from 🇮🇳 India.

[@EdgeMasterPro]

Waiting for a review of 2 to 1 headers and exhaust. Any dB measurements of stock muffler others sns. I actually don’t like loud pipes, and no I don’t rely upon car drivers and the adages loud pipes save lives. The 2 to 1 header and exhaust interests me from a weight saving perspective. For us street riders old farts not chasing my Horsepower I would love to see some videos on mods you recommend. For example front suspension upgrades and setup, having rack background puts you miles ahead. Other points like a boost plug if he helps fatten up the overly lean emissions profile. Some of us are chasing performance without chasing HP. I would rather hear about handling and performance mods from a mechanic with a race background vs some KZbin Tosser that’s made so many beauty mods to his bike it’s ugly and still can’t get his suspension setup after 6 months. Rims/tyres have you tried sealing up spikes and running it tubeless. Brakes, adjustable levers etc, lithium battery ecu chips etc.

[@marioaraujo74]

Wow! Congrats on the video, very natural and informative. I've been looking for more information about this road legal kit from S&S that includes the replacement of the air filter. Do you know if it exist, the kit? If so, do S&S sell the kit and do you recommend it? Thanks in advance! Cheers from Portugal 👌

Thanks for the comment but that isn't an "exibition" fixture. That's a production fixture we use to to verify fitment of every set of headers before we package them. It was just convienient to use it for the video.

I have seen the Super Meteor 650 exhaust in pictures and videos. I love the look of the dearly straight back pipes instead of the upswept and splayed pair on the INT/GT 650. I’m curious what the RPM’s are at 70-80mph so I can best choose the type of mufflers/pipes to go with.

You guys are the only ones on KZbin who have exhibited a cut-open RE 650 exhaust! Is its baffling and sound-absorbent material all metal? Do the after-market exhausts you see have mineral wool as sound-absorbent material?

[@REDSIX]

Y'all don't sound Aussie 😂 Great content!

[@trystanbanger6843]

Hey there! Awesome channel, thank you for all the hard work you’re putting into the content! 2 questions: Can any of the OEM engine guards be installed in combination with your header pipes?; would the S&S cams void the manufacturers warranty? Planning ahead and all that :-)

[@RevelryCycles]

The engine guards will def fit with the Revelry Headers. Questions about warranty should be directed to your local Royal Enfield provider as they vary country by country.

Thank you for this Vidio. Here in Germany the Police will stop you and when your Motoscycle is to loud, you can go home with a taxi. But we have S&S parts here with ABE.
