"drone" is experienced inside the car due to specific frequencies, you can't experience drone through your speakers since the engine is not present and it's the combination of the engines pressure wave and note that creates the physical phenomenon.
This is the best video by far. I've been looking for a video that demonstrates before and after sound effects with this ultra quiet vibrant resonator. I myself had my eye on this type of resonator to install on my 4th generation maxima. And I have been doing my research on the type of sound that am particularly looking for. This video helped out in determining the final application for my maxima. Thanks again
Yeah you are right. The resonator was needed and sounds great. I just picked up my project Z3 and it needs a lot of interior love and a little body work. The motor and 5 speed seems good so far. Drove it 20 miles home with zero issues.
My old Toyota xrunner was running dual in line vibrant ultra quiets with a custom turbo kit. It sound exactly like this. Has a nice pur during regular driving but when you get on it it’s not ear piercing. Good choice on the resonator
Definitely loving the Z3. Your exhaust builds are really really clean. Lotta talent. Sound quality is very nice and gives the car a more aggressive quality. Keep it up. 👌🏻👌🏻
Good job... I just did the same thing with my 3.8 V6 6 speed eclipse... I used a factory size straight pipe with a vibrant 12-in bottle resonator it's loud but it sounds good I might later on go with the vibrant ultra quiet resonator.
Good work! Think I made my decision for my E34 535i. I had the vibrant performance resonator on it and it was just too loud and raspy. This seems like the perfect balance, appreciate the comparison video.
I think the biggest offender and pretty common for whatever reason on BMW engines is rasp, there can be a few causes, and this did a good job curing that as well, its noticeable in before and after on the light revs during warm start to my ear. Loud engine noises are nice but when it just sounds like metal rattling around not so much, this is way better, more actual engine sound just enough volume reduction. Pretty good win win. Additionally i like duel pipes aesthetically but from single exit, or on most inline engines often don't like the way they alter sound, this one turned out good though, you still have some meat to the sound rather then it being too smoothed out. Must be just within margin of error i bet if you would of had even 1/8 inch larger on each the duel pipes wouldn't have sounded as nice.
I have a 2000 2.8i Z3 with the standard BMW exhaust set up. I have to say that I think the standard set up sounds great and I wouldn't want to change it. Each to his own I guess.
Nice, that sounds really good! I'm thinking of getting 2 of these for my 350z. I fabbed up a quieter exhaust, but it still seems slightly too loud. So these should do the trick
So, I have the same issue, sort of. I bought a "Becker exhaust", all stainless, quite the nice fit. (I was crapping my pants when I bought it thinking the fit would suck or the overall build would be horrible. It wasn't and I was pleased!) Anyway, the system eliminates the secondary cats and meanders to two rear straight through resonators. The sound is quite nice with no drone. However, it's the same thing, just a little loud .... I'm entertaining adding an x-pipe or an xpipe resonator where the secondary cats were located. I want to keep the sound, but just tone it down a tad. Mine is a 2011, so the secondary cats are located where your cat is right now. Any thoughts?
Because it really works vs the bottle style resonator which does literally nothing for noise reduction. A resonator can only do but so much. It’s job isn’t to muffle sound.
New 2022 Mach1 HP owner here. Im thinking about my Active Exhaust options to comply with racetracks that have noise restrictions. One of the options Im considering is replacing the stock resonator with two Vibrant Ultra Quiet resonator bottles. Other option is keeping stock resonator and trying to fit regular Vibrant resonators behind it. Last option is an H-pipe combined with ultraquiet vibrants. Although I love the stock sound, I want to avoid getting kicked out of HPDE events when I use the Mach1 at W.O.T. Ive read that some M1 HP owners just pulled the AE fuse while the engine is running in AE quiet or normal mode, before pitting out on the track. Any suggestions?
It sounds great but Does it drone? Do you think two would be worth it? I've been contemplating using these to replace the mufflers on my s2k. I cut the mufflers off another stock exhaust.I really liked the raw sound of just the resonator with the muffler delete but it's too loud and don't want a boomie droning aftermarket exhaust like skunk or tomi.
Did it also lower the interior noise or just drone? Did a muffler delete on a catless v8 and it sounds glorious but the drone and volume is just a tad too loud. Would love to bring it down 15% and reduce drone by a lot lol
BMW N54 335i straight piped, charge piped, and downpipes has entered the chat. Be honest, did adding a resonator help you "quiet down" via cold start? I ask because my neighbor is complaining about me leaving work at 430am and wants to report me for decible ordinance. Like, I'm not even letting the car idle long. At best, I fire her up, put the car in 1st, and drive off for 10 seconds until it goes quiet. 😅
Yes trust me it is way better. I had a 135 and used this same muffler. I have a couple videos on it but here is the latest: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-7K1ECUXQPIQ.html
im looking into getting a bmw z3 2.5i as my first manual here soon. The one im looking at has a muffler delete and Im curious would you say go with the resonator straight pipe or add a muffler back on? idk if it sounds louder in person compared to on video or not
how was the drone change over all? I have a 2016 Focus ST with a 3" SRS cat-back (off a cat-less dp and big turbo), and its nearly straight piped...its SO droney its unbearable. I was going to add this ultra quiet resonator, hoping it cured the drone. The exhaust sound and burbles/crackles is nice, but the drone is so bad i wont even drive it with the family anymore, resulting in taking my SUV on weekends until i fix the headache inducing drone cruising around 70-80mph lol...
came across your vid because i want to decrease some drone in my m37, not sure if i can fit 2 in place of stock resonators due to space. you think it would be dumb to add them same spot you did? in total 4 resonators in my system 😂
hows the incab drone when driving at highway speeds? Got a car recently that was straight piped to the headers and it's ungodly loud, as well as insane drone even with windows up... Wondering if this will help it out lol
@@Kordare I think on turbo car straight pipe exhaust works well. The turbo absorbs a lot the raspy noise that you would get with a resonator delete. I was surprised to hear the Range Rover doesn't really have that rasp kinda sounds like an 5.0 f150 from the inside though haha
Good evening. I tried to go to Facebook to contact you to ask question. I have 97 2.8 Z3. I need an engine or a rebuild kit. I have been trying to find a rebuild kit but cannot. I already have a cylinder head and gasket set for the top end. I need the bottom end, i.e. Pistons, rings, rods, bearings. Can you please advise where I can find such items as a kit. I really eant to get the Z back up and running. It is worth it to me. Thank you in advance. Jason.
@@Kordare any advice for me man, i got a 2012 civic and just swapped over to a 2.5 inch pipe and a 4.5 inch greddy muffler what resonator should i run and where should i weld it because this thing drones like a mf😭 thanks for replying bte
