Installing a Vibrant Ultra Quiet Resonator in my 2JZ 240sx

I bought a Vibrant Ultra Quiet Resonator to install into my 2JZ-S14 for a grand total of 3 resonators! Better to be too quiet on these California streets.

[@Nathan-wn5mc]

Complaining about exhaust and rumble in cabin but your neighbor's can still hear your fuel pumps lol.

[@droolguy]

Resonators only work to reduce a specific frequency, not to quiet a car down overall. If you want a quieter idle without loosing overall volume and sound you need a 1/4 wave resonator tuned for your specific cars idle frequency. Also, straight through resonators need a specific amount of pipe after the resonator to stabilize the exhaust pressure pulses or they don't work how they are supposed to. Which is why resonators are installed as close to the front of the exhaust as possible and not at the very end where a muffler might go.

[@JoseRodriguez-qo4hn]

William Barker does it help reduce rasp?

[@droolguy]

@@JoseRodriguez-qo4hn Yes, resonators can reduce or remove rasp but it's heavily dependent on the kind of muffler on the car as well. If you have a muffler designed to produce a raspy tone, no amount of resonator will help.

[@andyhnio]

When I put my Simons resonator on my car the Rasp/Krysp tone that I used to hear outside behind the car while accelerating, now it’s gone. The tone of the car is much deeper and smoother aswell.

[@jeivygarcia3428]

Helps reduce drone aswell

[@bigdogstreetperformance6761]

Listen to William... he knows what he is talking about!

[@theroyalcrownedtiger2946]

I have a Chevy Venture van, that had the muffler that was rusted out, and beyond repair, and I had a resonator kicking around in the garden shed, and put the resonator in the place of the muffler, with some welding of joiners, and it sounds pretty good, it's got the low deep grumbling sound at idle and at low rpms, and gets louder as rpms increase, but at the same time it's not unbearably loud.

[@piercer2]

I got a summit pump that’s loud like that and my exhaust doesn’t drown it out much, just bought an edelbrock quiet flow 122GPH and a vibrant resonator hoping the combo helps a bit

[@plugty1561]

Good review my guy

[@tbone5654]

Love my electronic cutouts, my 6 liter V8 is limo quiet with valves shut, press the button, valve opens, instant racing corvette sound. Can open part way for a sound in between.

[@PeterPan-rs8mg]

I think decibel metre will give you overall volume of the exhaust but what you get from the resonator I think it cut out the high frequency of noise.

[@MrLightning54]

Cool car / build!! I have the same issue on my 2019 5.0 F150, I just built a dual 3" exhaust after the catted headers, and I'm finding it a little too loud when starting it at 6am to go to work, and don't want to stir the neighbors, and searched out these Vibrant ultra quiets and found this video.

[@BrandonLee925]

Thanks man! Since you have cats, I’m sure these ultra quiet resonators will tame the noise. My 240 was almost stock sounding from the outside when rolling. Until I hit boost and cracked the wastegate.

[@smasch73]

It's more about changing the frequency and removing drone than the db levels

[@user-si7cr5lg4p]

From my experience, for a resonator to do its job, it needs internal pressure, which means having the right diameter in accordance to the engine size, if the pipe size is too large, nothing other than a chambered muffler would work, and even that might drone a lot

[@RezboaDog]

Thanks for this video. I am going to get one for my car.

[@psiturbo]

It is definitely quieter, and resonators need a few weeks to breakin. The only thing is I would have liked it sticks out more from the back of the bumper, now it looks as if it has a missing section of the body kit, with a huge hole.

[@user-or1xh1vc8n]

Any changes you make to the exhaust will have little to no effect on sound the closer it is to the end of said exhaust. However, if you make a change to the exhaust at its very beginning (Like the headers), then you will see a larger effect occur. For example: Removing the muffler at the end of your exhaust will not have anywhere near as much of an effect on sound as replacing the stock manifold/precat with open headers.

[@carlocastillo1036]

'IS THAT AN INTEGRA" *cleans glasses*

[@BrandonLee925]

To that man, any modified Asian vehicle is an Integra LOL

[@slowvq9371]

Highly doubt that app on your phone is anywhere near accurate 🤣

[@DJJumpdancer]

the police in Germany uses their phones to measure the db of your exhaust if they think its to loud

[@alvin59accent]

Maybe the Dynomax 17296 could help with the sound is straight and freeflow too check it out doesn't have restrictions

[@robertoramos2728]

Legend 🙌

[@chronosxiii4702]

So my question is can one of these replace a stock resonator on a car note: my car is a 04 Altima 2.5 just a daily driver my friend bought this part and just gifted it to me not sure if he's correct that o can just have some one weld it on to replace my broken stock one some one please advice if this is correct ? If not I'll just buy a direct fit replacement to the broken one and sell off the one he gave me also note he gave me a vibrant resonator

[@BigPalmK04]

Decibel meter is probably picking up the fuel pump noise. 😂

[@BrandonLee925]

You’re probably right, those things were loud. The car was just loud in general lol

[@raymondchen6720]

Hey what’s the app that you used for decibel readings? That’s would help me a lot

[@slider2828]

Damn your just in walnut creek.... You still have the S14?? Would be great to meet up at Track day.... I will be doing more SpeedSF stuff with Patrick this year

[@BrandonLee925]

I don’t have the S14 anymore, unfortunately. I currently have an E46, that needs a lot of work before it gets on track. Might get something else, just so I can get back on the track sooner.

[@MitchChubey]

"Having a loud car in California is a bit... dangerous!" Made me laugh. Vancouver BC is the same way.

[@BrandonLee925]

No kidding! CA is crazy, but gotta pay to play the modified game.

[@djsthemetereman]

Gotta come to Jersey cops don't bother you at all, some cars are so loud it sounds like gun shots.

[@theroyalcrownedtiger2946]

In Canada, Ontario, the cops here don't bother you, as long as it's not unbearably too loud. I do see / hear cars with mufflers that are noticiably louder than stock muffler, but not unbearably too loud.

[@MrBigR928]

Sounds better 👍🏿

[@310Cowboys]

Which app or website do you go to for the sound decibles?

[@FZERO20]

Bro you have no power steering? Me neither. It sucks but tbh I’ve gotten so used to it now that I’m not even investing in a new rack. I just keep buying performance parts😂

[@AllCarsEverythingOfficial]

Don’t resonators work more for drone? Maybe it’s quieter when the rpm is a bit higher. Otherwise I think a muffler would be the way to go

[@BrandonLee925]

True, a muffler would help to lower exhaust noise at all levels. Only reason why I didn't go with a true muffler, is that it has walls and chambers that redirect exhaust flow and cause back pressure/restriction. My goal was to make the exhuast as free flowing and quiet as possible, but ever since the GSC S1 cams went in on the new 2JZ, the engine is much louder at idle.

[@AllCarsEverythingOfficial]

@@BrandonLee925 Thats a tough one to solve man

[@BrandonLee925]

@@AllCarsEverythingOfficial I'm thinking, maybe a muffler and a cutout lol, we'll see.

[@AllCarsEverythingOfficial]

@@BrandonLee925 Cutouts are the best!! loud for shows and quiet for neighbors!

THIS MAN HAS KEY HOOD PINS I AM DONE. All safety measures so someone doesn’t take my fucking supra under the hood😂😂😂

[@brown55061]

It's hilarious how many people say mufflers are too restrictive when people have show on a dyno that you can take the muffler off a car and you MIGHT gain 2-3hp even with a v8. So if you want to be able to hear yourself think, just put a flowmaster or dynomax on there with a little packing and it will only rob you of a few ponies and you'll actually be able to hear the radio. If it's a racecar why do you have mufflers at all lol, gut it and open pipe it.

[@villavine10]

“Is that an integra?” My face: 😮

[@BrandonLee925]

😅

[@riffracingteam]

Resonators change tone and drone remove rasp don’t change volume really you need a muffler for that

[@hiaceglxr]

How accurate is the phone app vs a dedicated db measuring device? I think he should have made a. Comparison between the two, should have mounted it further upstream I think though...

[@BrandonLee925]

I don’t think the phone measures too accurate tbh. But I had a few other resonators in the car already lol. From the outside the car sounded pretty quiet until the wastegate cracked. Inside the cabin, car was loud regardless 😂

[@garymathe9863]

Mufflers muffle (quiet down the sound), resonators cut out drone/rasp. Pretty straight forward, no?

[@woooose]

My mazda had no muffler and was too loud(neighbors) when idling. I got rid of the stock resonator and replaced with a vibrant and it was noticeably quieter when idling. Could no longer here it from inside the house. Now im about to do the same thing to my 97 z28, no muffler and 2 vibrant resonators if I can get them to fit. I guarantee you it's going be more quiet after I do this next week.

[@yawny9710]

@@woooose did adding a second UQ res quiet it down further? I noticed the same on my Mazda, 2.5" cat back no muffler with stock res (directly after cat), replaced stock res with UQ res and it was noticeably deeper and slightly quieter. I'd love to hear your results!!

[@goofofff]

Lol my neighbours never interact with me when my cars out. I don't daily it tho.

Crazy how everyone 240sx boy wants to swap in a JZ, now making 1jz and 2jz so damn expensive for everyone.

Nice Teggy lol

[@jspeedking]

You’re most likely going to notice a sound difference under load.

[@gtgodbear6320]

Someone should make a resonator lined with those soundproofing triangles the whole length of it. They would probably kill any drone at least.

[@michaelnone6322]

How much does it way aprox? I need to add something to my mustang gt (gonna have to use 2) but need to be quieter. Thx!

[@BrandonLee925]

It’s fairly hefty, I’d say around 10lbs. Depends on how long of a resonator you get and diameter. These things are thicc lol.

[@HoweDoYouDo1999]

All that work just to open a hood I think even thieves would have work cut out for them. Shit there must really be some people willing to run up after this car😂

[@RobowSter]

Hey bro if that’s a resonator why did you make it as a muffler? Can you use resonator as a muffler? Im asking this because the shop that i went to, installed this as my muffler on my accord 2.0.

[@BrandonLee925]

Most straight through or pass through tuner mufflers are typically just resonators.

[@RobowSter]

@@BrandonLee925 ohhh i see. Thanks bro!

[@playzboi4784]

I have a q50 and have test pipes and notice a rattle rasp on my invidia resonators can this help ?

[@BrandonLee925]

It’ll definitely make it sounder smoother and take out most of the rasp.

[@60ticks]

MY EYES!!!! 👀🙈

[@fostinator69]

Would this help with drone at 3k-4k rpm in my 03 xrs?

[@BrandonLee925]

It should, that's like the main thing resonators combat.

[@Jordan-rb28]

What do you think a muffler is for lol

[@jscheurichIV]

Resonators only work when put in the front half of the exhaust.

[@BrandonLee925]

This was also the 3rd one lol. It did quiet down the car on the highway from outside the car though. It sounded like a hybrid until the wastegate cracked open. Inside the car and idling didn’t change much of anything though lol.

[@vammyhouse5206]

Is that welder from harbor freight? I want to try welding at home

[@BrandonLee925]

The welder is a Lincoln 175HD, you can buy a Lincoln 180HD from Home Depot or Lowe’s. The new Vulcan welders from Harbor freight are pretty good though, a few of my buddies have them and they lay down some excellent welds.

[@MrCoolbeanstogo]

what kind of welder are you using?

[@BrandonLee925]

Lincoln 175HD with 100% C02

[@LowestDig]

Resonators change the tones and frequency of sound not the volume

[@henrylima6974]

Dude get a muffler, no wonder your car is too loud...it aint got a muffler, lol

[@MrKnoxshus]

right! i was saying the same thing, mufflers reduce sound, resonators reduce drone

[@driftergonewild]

Did you use ss wedling wire?

[@BrandonLee925]

That I did! The whole exhaust is stainless. Wasn’t cheap to build lol.

[@Jp88552]

Resonator goes as close to the headers as you can you have put it where a back box should go 😂

[@BrandonLee925]

I have 2 others located further up the exhaust towards the down pipe. This is the 3rd resonator on a 3in custom turbo back exhaust. Pretty sure the cams are to blame for the car being loud at idle. I would need a true muffler in order to combat the noise, but I didn't wish to add restriction. Cruising at speed, the car is very quiet.

[@Jp88552]

A decent muffler won’t cause too much restriction

[@FZERO20]

Bro doesn’t he live next to you? He just now asking that?

[@BrandonLee925]

Basically! Lol

[@brentbonham9427]

Which cams are you running?

[@BrandonLee925]

GSC S1 cams

[@MrDeepzek]

I'm no expert but where you installed it is not really proper. You need to install a muffler in that spot, resonator goes deeper inside somewhere in the middle section. Get a muffler and replace it

[@BrandonLee925]

This is the 3rd one lol. The other proper locations already have resonators. But you’re right, a muffler would have been better in this location. This resonator actually quieted down the car a lot from the outside, on the highway other people couldn’t hear much until the wastegate opened. Inside the car was like the same 😂

[@Thomas_of_Time]

This is actually very disappointing. I was looking into buy this resonator for my sti since my bellmouth dp and nur spec cbe make the car pretty loud. Guess I'll keep shopping. Great video though

[@ejayone8184]

3 resonators, instead of just a resonator and a muffler??? Why not just put on a muffler if volune is a concern???

[@BrandonLee925]

I didn’t want any restriction lol. They actually made the car very quiet from the outside. Inside the car, with all the solid mounts and gutted interior it was still loud though.

[@DJJumpdancer]

7:49 that thing is way to quiet now cut the resonator back out xD

[@BrandonLee925]

🤣😂

[@bkfill]

I dont think your first DBA test was valid with the car behind you, Might of been boucing sound off the 2nd car.

[@MrZaine97]

I’m just laughing at the fact that you thought it would be a little bit quieter. Boi I thought you would of been getting a muffler. Sounds good though

[@BrandonLee925]

Yeah... well cruising on the freeway it's silent lol. Just idling it's loud. Might install an electric valve to muffle the exhaust.

[@MrZaine97]

Hello yeah that’s what’s up. For me it’s like I might just get a muffler to get more rumble outta me. I’m too raspy at high rpm. I wanted more of my I5 sound.
