Resonator Delete

Sounds like a cross between a John Deere tractor and a Homelite chainsaw.

Good God fellas, you think that sounds good?

U just can't get an 8 cyl w/headers sound out of a 4 banger especially running a turbo. Yea doc, I'm 1 of those (67 yr) old guys. Hahaha!

Yup, you can’t make a sports car Inline four cylinder sound like a v/8....

you shouldn't remove resonators they do alot more than just make your exhaust quieter

well inside the cab they can lol

Well that sucks. Makes you wonder why they had a resonator in the first place. At least it didn't make anything worse.

Hmmm, now what do we do? I think you're right, probably have to try a replacement muffler. Time to research a small subtle muffler with a deeper tone.

More than just the reduction of noise, an exhaust resonator also improves the overall performance of the engine. You will end up having a smoother driving experience since the car can produce higher horsepower and use less fuel. In a nutshell, it also improves efficiency.

Hahahahaha!!!
I guess ur right. They could make the cab sound like a 5hp peddle bicycle if they wanted 2.
Hahahaha!!!

Can you elaborate on this?

Soundaktor
From Wikipedia, the free encyclopedia


Jump to navigationJump to search
Soundaktor (German for "sound actuator") is a vehicle audio system used to simulate engine noise in the cabin of some Volkswagenautomobiles. It consists of a speaker mounted on the firewall between the engine and the cabin, which adds noise to the cabin in order to replicate the driving experience of older vehicles that had lower levels of sound insulation.[1][2][3][4] This system was introduced in 2011 on VW's Golf/GTI,[1] and has also been used on the Jetta/GLI, and Beetle Turbo.[2] The same technology has also been used in other cars from Volkswagen Group, including the Audi S3 and Škoda Octavia vRS.[3]

The sound generated by this device has been described as "a sort of buzzy, fizzy noise".[3] It has been reported to play a digital recording of engine noise,[2][4] but Volkswagen claims that these reports are false, and that it reproduces the actual engine noise of the car.[5] Some diesel cars produced by the Volkswagen Group also have an "exhaust soundaktor". This system uses additional speakers in the exhaust system of the car to generate "a low-pitched, roaring sound" intended to make the car sound less like a diesel and more like a conventional gasoline engine.[3]

Other vehicle manufacturers have also used artificial engine noise systems, implemented in other ways. Some models of the BMW M5 add noise to the car's audio system, for instance,[1] and the 2015 Ford Mustang also added a system for sending the car's engine noise through its speakers.[4] Multiple manufacturers have shaped the engine compartment or installed resonant pipes within it in order to direct greater amounts of actual engine noise to the cabin,[2][3] a system also used by VW before switching to Soundaktor.[2]

here’s one way to do it...there are all different kinds !

I know what that is. A resonator is part of the exhaust

 

[lohchief]

That still doesn't explain WHY one shouldn't remove the resonator. Or outright replacing the exhaust system,as so many have done.

I think Indy was referring to an in cabin v/8 engine simulator.

The Short Answer:

Resonators are often times confused for mufflers and while they may appear similar and share some of the same jobs, they play an integral part in producing optimal volume and tone from your engine. They also have an important role in the exhaust evacuating process, which helps your engine produce more power and reduce fuel consumption at the same time.

The Long Answer

When it comes to exhaust systems, many people know the basics. Things like the header, catalytic converter and muffler are all terms that you hear often but one that often goes unrecognized is the exhaust resonator.

While you might mistake it for a muffler, the resonator actually has a very different and important job to do when it comes to your vehicle’s exhaust. Here’s a quick look at what it does.

Gas Pass
As your engine’s exhaust gases leave the combustion chamber, sound waves bounce off of the walls of the pipes and ricochet all around creating both high and low frequency noise. As engineers analyzed and improved exhaust systems, they realized there were advantages to be gained in organizing and controlling these pulses and came up with the concept for the resonator. Essentially it acts like a large echo chamber that takes the exhaust pulses and optimizes their frequencies to achieve better fuel efficiency and power production.

Set the Tone
It may look like a muffler, but the resonator’s primary function is to take the sound waves created by the exhaust pulses and fine-tune them into a more organized pattern. While this helps improve power and efficiency, it also gives your vehicle its distinctive engine sound. Whether you have a Dodge pickup or a Ferrari, many cars have their own signature sounds and it all comes from exhaust resonators.

Go With the Flow
Part of the combustion cycle involves the pistons pushing spent exhaust gas out of the chamber before filling back up with fresh air/fuel mixture, but because the elapsed amount of time this takes is short, exhaust gasses would move very slowly if not for other forces pulling the gas through. Today’s modern combustion engines also use sound waves to help evacuate the combustion chamber and move the exhaust down through the pipes and out of the muffler, and this action relies heavily on the resonator. By tuning the pulses of exhaust gas to work together, it creates stronger waves of exhaust that vacuum the gas out more quickly.

Volume Control
Aside from producing the tone of your vehicle’s engine and helping move exhaust gas along its way, the resonator also plays part in controlling the volume of sound that your engine emits. By manipulating the frequency of exhaust sound waves, it can either give your car a more throaty and loud tone or silence it for smooth peaceful driving.

You can turn off the sound enhancement with Forscan.

sorry, do not know how to do that yet, pics yes vids and sound no

Please......................

My 500hp 2.4 Dodge had great sound to it, and did not sound anything like a bee trying to hump a dolphin.
My question is how do you get a BI Turbo Diesel to sound good?

Don’t know, I did a muffler delete...

Good info, but I don’t buy it lol these things aren’t two strokes... Definitely didn’t notice any performance or fuel economy difference.
