Vibrant Performance 1141 2.5' Ultra Quiet Resonator, Silver

God am I IMPRESSED. First of all, I have the supercharged v6 from Audi. Catless downpipes and literally zero sound mufflers or resonators (owner before me took them off). Car literally sounded horrible, if yk anything about this engine it is extremely raspy. Did a bunch of research and everything just kept coming back to these resonators and holy hell they definitely work. Rasp is damn near gone. The drone on this car was horrible but after installing these, I’m getting no drone at low rpms. Quiet when cruising and screams when you floor it. I was initially planning on getting a set of valved mufflers just cause I was assuming a pair of resonators weren’t gonna do much to a fully straight pipes system but I might put that off for now because of how good these are. They are a little too big depending on where you want to put them. I wanted them placed in the stock secondary resonators spot so it did require some extra tubing to make things fit and i had to have them standing up cause they wouldn’t fit next to each other while flat but it doesn’t make a difference and you won’t even see them. 100% recommend these. Ik there are some cheaper alternatives that look exactly like these but trust me totally worth it for the quality.

Installed on a 1989 Volvo 245. And it worked perfectly for my 4 cylinder engine. I built my own 2.5in exhaust after I swapped in a 1994, 940 turbo engine. It was 2in before. I used a magnaflow muffler under the seats but it had too much drone. So after a ton of research I went with this to help, it killed all the drone! My car is insanely silent now exactly how I wanted it. It sounds like it has zero modifications even though I have done alot. Its a true sleeper now. I love it. Its small and easy to tuck up high to keep out of the way of getting damaged. I can hear the turbo alot better now and it seems to spool a little faster. It also took care of the annoying popping from my exhaust.

I purchased an MBRP cat back exhaust for my 2016 Veloster Turbo. The exhaust only came with an mbrp resonator which was positioned at the beginning of the mid pipe. The exhaust was very loud and obnoxious at highway speeds. The drone was almost unbearable. After doing some extensive research I find this Vibrant ultra quiet resonator. I was very pleased with the quality of the resonator when I first unboxed it. The welds are very nice and the unit is very solid. After finding a good place to mount it i had a friend modify the y pipe that originally came with the mbrp exhaust and weld it in place just before the tail pipe. I couldn’t be more pleased with the sound. It’s a lot deeper and only gets loud around 3k rpms which is ideal for driving through town, cold start idling and even better when traveling on the highway to and from work. I would recommend this product to anyone that’s looking to cut down on the drone of an aftermarket exhaust and the over all volume while maintaining a great exhaust tone.

Great resonator. I have a 3.6l V6 supercharged Jeep JKU with a cat delete ( I melted those poor cats 😅) and a AFE catback exhaust muffler When i removed my cats and had only the muffler it was much more louder and raspier then when i was catted. You could easily heard it several blocks away. It was extremely annoying driving around and all you can hear is raspyness and drone. So i decided to take a chance on these resonator since i read all the great reviews on it. To my surprise it made much more of a difference then i expected. It completely removed the raspyness and the drone that was bothering and all im left with is a nice deep sound. At first when i first cold start my vehicle it sounded like when i was still catted and i was like wow that did not do anything. But to my delight after i reved it several times i was amazed on the sound of the exhaust. Decided to drive around and do some spirited driving and i could hear more forced induction noises over the exhaust vs vise versa from before. Im quite the happy person

I had this on my Nissan ser spec v. 4 cylinder with headers and no muffler. This resonator made this not sound like complete trash. Highly recommend, this is like the Honda anti rasp secret. Can confirm and recommend

After reading all the reviews this sounded like just what I wanted. Something to clean up the sound but not silence it. However in hindsight, something called “Ultra Quiet” is probably going to do quite some silencing. I’d say it added at least 50% silencing compared to before. But on the bright side, it did clean up most of the exhaust rasp I had, so overall I’d say it’s worth the money, just note it does make things a lot quieter (I was running a straight pipe with a rear silencer before and it was very loud)

Best muffler for my exhaust

these are as good as everyone says. i initially tried a knockoff resonator and it didn't do much for drone. i finally installed this one its place and wow what a difference. coupled with a Vibrant bullet resonator mid pipe, and a Vibrant Street Power muffler, my Kswap car sounds excellent with no drone and no restriction. i never would've thought 3in straight thru exhaust could sound this good (quiet) while idling/cruising. but because it's no restriction, it still screams when you open her up
