★ Making Exhaust BAFFLES & SOUND TEST On The CB750 Cafe Racer

[@japsniper1980]

I enjoy this channel because we actually see you working on things, and not just a jump cut to the finished thing your making. Also not everything works, and you try different methods of making these parts.

[@CafeRacerGarage]

I appreciate that, this kind of comment helps me make even better videos that you actually want so a thank you for taking the time to let me know this :)

[@DragonSol42]

You are certainly not the only one who forgets the small things when excited for a project. Unfortunately I occasionally forget the big things like personal protective equipment.

[@bossebiceps6810]

Always remember, safety third

[@tarzanmukai808]

I just wanted to comment on your Great Instructional Videos, truly working the project from start to finish and giving us your comments to help us viewers and DIY builders in our own garage.. I just bought my first classic bike 1980 Suzuki GS250T, I have have finished removing and treating heavy rust and painting of the wheels, engine, and frame, and reinstalled everything back together aside from he carburetors and fuel tank, Again Thank you for the Awesome!!! Instructional Videos, Always Learning Keep Teaching!!!!

[@CafeRacerGarage]

Thank you mate and I hope to see more of you in future comments 👍

[@johnDukemaster]

A good neighbour is good to have...so does your neighbour think! Well done sir!

[@gregmoppett8425]

Your timing on this couldn't be better Dan! This "new" 82 Virago I told you I got is obnoxiously loud. 1hr ride and my ears were hurting. In trying to figure out how to remedy that you may have just given me the answer! Cheers heaps yet again mate! Keep it up!

[@quadbuilt5987]

I have been really looking forward to this video and once again you provided an awesome detailed and relative documentary account of the processes involved in manufacturing and constructing custom exhaust baffles while detailing the cause and effect relationship of the modifications. Loved it and agree the tone sounds spot on.

[@mikedelta1264]

Great vid. I have two CB750’s (big bore) 79 & 81. If the carbs aren’t clean (ie jets deliver same quantity of fuel through throttle range) and haven’t been balanced/synced the exhaust noise is considerably louder.

[@BareBonesMotorcycles]

Great video, very good instruction. But those apps seem awful. I got an actual db reader when i built the exhaust on my CB. Phone microphones just arent up to the task.

[@bez2944]

I had the same bike and tried so many things to get it to sound good but nothing worked. I tried all kinds of baffles. Bought some, made some, nothing ever worked. Always too loud. Ended up doing something that seemed wrong, but was the best solution.. i put a cap (round disk of sheet metal) blocking off the exhaust at the tip. Seems wrong, but was definitely the best it got.

[@MotoGoato]

the cct on the CB is a hydraulic auto adjusting type ... you'll probably find that some of the hydraulic oil ways are blocked with a bit of crud .. usually removing the mechanism and cleaning it all out sorts the issue. Love the sound of it at the end of the video .. pretty much perfect😊

[@gp85hkg]

55 seconds into the video and I'm understanding your English. Subscribed...now back to the video (".)

[@CafeRacerGarage]

Haha Aussie English 👍👌

[@garyyorke1080]

Sounds a lot better with baffles and mufflers .you can hear the tone difference but not too sure on those apps one didn't look like it moved much . 8 am so before brekkie today .. great video as always Dan thanks

[@CafeRacerGarage]

Yeah I agree, Glad I made it before bacon and eggs :)

[@ToninFightsEntropy]

I used an app for decibels this way yesterday, and the first thing I tested was the maximum input the phone can register.. Turns out it's not a lot, so I ended up putting my phone in another room, to get readings within its range.

[@BOBBER400]

I'm baffled by most of your projects but it did sound nice & deep in the end : )

[@CafeRacerGarage]

Okay you outdid yourself on this comment 😂😂😂😂😂 I actually did laugh out loud

[@sirbow2]

You guys are exhausting :P

[@Jish2ndGear]

Only just getting round to watching this video but ill have to say perfectly executed my good sir 👌

[@sparklygames71]

This was a very exhaustive video, bike sounds really good

[@Thewatson77]

Great video Dan 👍🏼 Making your own custom baffles is the ultimate way to do it. I think the sound is spot on now. And yeah...I forgot stuff too when I get excited 😂😂

[@tammyforbes2101]

Yea I gotta do this for my GSX-S1000 it is straight piped right now and it’s little to loud and I like the deeper sound that comes with a can on the end!

[@BillCook62]

God job mate. Just thinking you could use a step drill or a cone cutter to open up small drill holes.

[@mwng5186]

Great and onformative video mate...thoroughly enjoyed it...I have a question if you have the time.....I have a new can with removal baffle...without its far too loud....with...its a little quiet....its a long tube with around five ridges around 10mm long sticking out along its length....would you recommend cutting a few off or drilling some holes in the ridges or shaft? or would I bugger up the bag pressure or what not? thanks in advance..matt

[@garya3056]

This was very instructive, Dan! It’s always “baffled” me lol! I have an immediate use of this info... 🏍👍🏍

[@CafeRacerGarage]

Thank you mate, just learning as I go :)

[@GearShifter925]

Great job man....!!!!! 🔥 Btw what's the name of that mobile app for measuring exhaust sound???

[@Mojokiss]

my cb750 DOHC has the rattles but only when things aren't running well. so far it's been ok around town

[@michaelandrew3874]

Awesome work as always. One thing I would add, I have done it before. You can buy catalytic converter, slip in type that drastically make improvements in noise reduction.

[@CafeRacerGarage]

Thank you mate. I’ve not even thought of this idea. I will look into it 👍

[@mancavecustoms13]

Just when i was trying to find something of this sort. Been rebuilding OEM yamaha xs400 pipes. Removed the 2nd baffle and might weld it back up with the original single baffle. Should be much better. Great info mate, instant Sub :)

[@rebuildranch1225]

The Green Decibel app appears to not like bikes, it never changed! But there is definitely different tones on each. I agree the raspiness was toned down.

[@CafeRacerGarage]

100 % said it perfectly brother :)

[@tiagoperini]

@@CafeRacerGarage , whats that app

[@prototype9904]

Thx M8 ~ This is exactly what I was looking for Well Done !!

[@paultaylor319]

Great job man, The USD forks look slick, What are they off ?

[@TheCoooool123]

Lube your cables man, that usually helps, my throttle cable was bent into a total s shape because I went from ape hangers to drag style n once I lubed them up it worked perfectly

[@mtn.srlrascu6675]

I have made more than 15 modifications on my dbkiller and 3 pieces… I have a stainless steel workshop. I can say a few things after i done so many test and mistakes

[@UpsideDownFork]

Great work! Inspired me for my next project!

[@CafeRacerGarage]

I love that 🤌 Thank you so much for the comment

[@Grympel]

Nice video! Didi you sand blast with water?

[@motohub539]

From Manila Philippines..... great

[@shedenvy691]

Excellent work as usual,really makes me want to make some baffles and maybe some jaffles to eat while making baffles.

[@CafeRacerGarage]

Sounds great! HAHA 😂

[@minkynick]

I've been following you from day one. Love the way you build things and love the bike so far. You've encouraged me to buy and build my own bike so fingers crossed it goes well. Keep up the good work pal 👍

[@CafeRacerGarage]

Awesome, thank you! just remember its all about the journey not just the end :)

[@carlosortiz821]

Hi there man! This video help me a lot to modify my current mufflers on my Scout 18´, the only thing different is that i bought the DB killers insted of making them. So far i tested without the FG but i´m gonna try with your method... Cheers from Chile!

[@CafeRacerGarage]

Glad to help my friend

[@tuntiope8681]

I hate those too loud totally empty pipes, makes the bike sound like a broken car. For some reason specially on cx500 they do too open pipes. Thanks for the video, i have one cx500 project in the future and i will do these baffles even if it takes a day or two to make. I usually use real mufflers on my builds so i don't have this problem. Keep up the good work.

[@madeleyinc]

90db or under makes all pipes sound awsome.

[@jamesruralsparkynz3504]

Sounds bloody good mate! Great Video

[@CafeRacerGarage]

Thanks 👍 It sure does

[@monsterAndZAZA8206]

Always a great video bro 👍still working to finish mine

[@syednaseem567]

Good quality exhaust system super brother . Vary nice

[@mwtraining4310]

Sounds amazing!!!

[@jamesabbott1309]

Awesome job, Dan! Thank you for the inspiration, I can't wait to see the finished build!

[@CafeRacerGarage]

Thanks James I really appreciate you taking the time to leave me a comment like this, You’re definitely not alone on wanting to see the bike build finished 😁😁

[@scottminshall6420]

Excellent work Dan!!!!

[@CafeRacerGarage]

Thank you so much Scott. I’m super happy with it now

[@axelzanelli1348]

Thanks for another Great video Dan!

[@stevenkasander3374]

Hi there! Enjoyed your video. What would you recommend with the wrapping material? How do you secure it and wont the material come loose?

[@CafeRacerGarage]

Fibreglass exhaust baffle material and use galvanised wire

[@oinnhugiagustsson2547]

Love the helmet and the color on it

[@TheMarkFromDenmark]

you need to use a Spectrum Analyser app, as only showing the peak will not tell you anything use the waterfall mode to show the difference between them

[@fog99uk]

Sounds so much better with the mufflers and baffles. Do you notice the guys who always cry 'loud pipes save lives' all ride black bikes, wear black gear and a black helmet?

[@CafeRacerGarage]

Haha you have a really good point. I never thought of it like that :)

[@oscarbonilla2862]

Any risk of creating too much back pressure using the fibreglass matting method?

[@jonathasfigaro4992]

This engine is a simphony

[@stevieb9104]

Wow! All I need now is a $10 Million dollar machine shop and I'm all set!

[@ghufrontaja7658]

Good job bre.... Mantabbbb.. 👍👍👍

[@youtuup]

Is the fiberglas something special or can I buy this at "every" toolshop.

[@syednaseem567]

Good luck friends 👍

[@Gixxer983]

You got to put baffles on the end of exhaust to make it work properly. Half waying it is just half way.

[@rahulrane1658]

Nice job man

[@TulsaMotoClub]

Hey bud I've been meaning to ask you. Have you got plans of any sort for the lift you made?

[@lukecrowster1231]

Definitely has me motivated to make some for my bike, appreciate it

[@CafeRacerGarage]

That’s fantastic, I love that 👍

[@milansiwakoti3774]

you just got a new subscriber

[@edmunamarilla2540]

Good work mate

[@dewdrop3009]

Funny thing is I'm not doing this for my 1978 cb750K. I'mma make a "baffle/resonator" for my 96' dodge ram 5.2 mag. I'm just doing a muffler delete but want to muffle it just a little for cheap

[@gc33]

Thanks from Perth mate... Just subbed.

[@littledog1312]

It sounds great

[@remfanuk1970]

loving this build Dan...a real inspiration. what's next on the horizon?

[@geneydemmy9183]

[@g.posselt]

Subscribed. thanks u can lube this trothle cables also its a little messy but works

[@sabithfatha6963]

I wonder about his talent,workshop and tools 💪 Can i know what is that you wraped on that white color sheet ?

[@CafeRacerGarage]

Here you go mate amzn.to/3cR7yk4

[@garyconstant4234]

Does it make the bike run hotter

[@joelouisacevedo9558]

It's really nice Use steel wall it works

[@edwardramirez8027]

Very nice sound

[@chrisdadigger1018]

Sweet bike

[@andrescartagena8656]

I have a honda cb750 1981 cafe racer, can you tell me what kind of tires are the ones in this video and the brand, please.

[@scottdog182]

Sounds much better mate, maybe needs a tad more to get it around 75db on tick over. That first run sounded almost Harley like (6.46). Nice deep tone though.

[@CafeRacerGarage]

100 % agree with you. It’s easy to make it quite but the restriction of flow is the issue

[@ErrtuZarathos]

Phone mic is made to pick up low sounds and turn down high sounds. So your dp reading is mainly the same.. get low price sound meter is better.

[@freemovies4555]

I like your accuracy . please i want your advice; i have yamaha sr 250, and i want make fours holes in the frame , just a small holes to catch a box( i see it better than welding pieces of metal), and I thought it could cause a crack; you know the road and the weight.. what are u think?

[@sjv6598]

I’m no expert but every aftermarket exhaust seems to have the db killer in the end of the silencer and not in the exhaust tube before it? Great looking bike though 🙂

[@CafeRacerGarage]

Yeah you can put the DB killer anywhere you want I just put it at the end because it’s convenient, could even run a straight pipe, and just put a DB killer in it with no muffler if you wanted to

[@BlueSquatchproductions]

Ive definitely have forgotten exhaust clamps

[@valga1200]

Hi, quick question, you showed us a while ago a video of one of your friend building a BMW K100 cafe racer, and toild us that you planed on doing a follow up. Do you still plan on doing it ? Where is he at ?

[@CafeRacerGarage]

I can definitely do another video but there hasn’t been much progression on the bike apart from it’s completely apart at the moment and maybe a bit of paint and bought a few parts

[@Piotrz81]

Please show us how you tune engine to this exhaust

[@antwolff1426]

Another great vid mate. If you need spare parts ive got my original engine just sitting in the garage, 93 model. Not too sure how good the parts would be seeing as though its got about 110k kms on it and has some other issues.

[@CafeRacerGarage]

Sounds great, I would love to rebuild a full engine just as a learning project on the channel. :) Pm me on instagram if you want to chat more about this

[@RehmanRehman-bt3zb]

Like the sound but Love that helmet 👍

[@tancakar8987]

probably the bike has some back pressure and needs the fuel air adjusting but besides all that plasma cutter is amazing :D

[@gfbasagre]

damn good job mate!!!

[@jholloway77]

Sounds great!!

[@CafeRacerGarage]

Thank you John, Yes it sure does, Maybe still a touch loud :)

[@mikmarumoto1012]

Hellow sir !😁✌ ilove your videos🇵🇭

[@peterdouglas4073]

Just fitted a Supertrapp 2into1 mid pipe to my 883 sportster. Having issues with inversion wave. So thinking of coping your baffles and opening the back of the muffler. Could you put the baffles halfway? Before it goes to one pipe?

[@petrklier6611]

Hi, did any of you guys have to take care about rusted out muffler? I mean the inner tube - hole on the bottom part. I have a cbx750 from 1984 and one muffler is rusted out and little pieces of rusted metal are making unpleasant noises and since “new” stock looking exhausts are expensive i thought it could be repaired by drilling out those rivets and taking the tube out, weld those holes and maybe wrapping in muffler fiberglass (if it originaly had some idk). Do you have any tips?

[@genneltorres4500]

Sound good

[@ruzpcavz84]

Very nice move sir

[@StraightLineCycles]

What about putting one hole saw inside of another hole saw essentially cutting 2 holes at the same time.

[@CafeRacerGarage]

Great Idea, Iv actually tried this one and its a good trick but I didn’t have the right size hole saws for this project :)

[@AZ-qn3xq]

hello, what pipe or tube size do you use for custom exhaust pipe? I have honda cb450t, i would like to make a new exhausting pipes. I dont have any experience :). So could please explain some basics about that? Thank you, Alex

[@dylano7242]

Think loud is bad ass until you lost your hearing from it. Let alone yiu cam hear what's going on around you for situational awareness.

[@vstar7196]

Any baffle can be converted to a quiet baffle, especially on the V&H mufflers.

[@johnlyngdoh1959]

Ilove this bike

[@beastblogger.]

Can this fit on interceptor 650

[@bradwinlovell7047]

Cool video

[@Gus-cg9yp]

Hi , if the neighbour does not complain, leave it there Dan, lol . thanks . Gus

[@CafeRacerGarage]

Haha thank you Gus, Its my hearing also LOL

[@xtruma]

How did you do the exhaust to make an inline 4cylinder to sound like a v2 harley?? thanx for answering, as I am planning on modifying mine to make a 4-2 exhaust with cylinders 1+4 on one pipe and 2+3 on another...in hope to get a harlety type sound

[@dalepaddon8904]

Did you wrap your baffles in the end? I modded my baffle with the tabs & end plate & wrapped it but I find it just blasts the packing out. To the point where I wonder if I’ll end up with big holes in the packing where I bent the tabs down.

[@CafeRacerGarage]

Mine was fine in the end :)

[@arthurwinter1878]

Pls what name of exhaust and which company
