I really want to improve the exhaust note coming from the car, especially under acceleration. At the minute, you can't hear the exhaust over the engine.

 

I've read most of the posts I can find on modifying the exhaust, but none seem to suite what I'm trying to achieve.

 

What I'm trying to achieve is a nice exhaust note under acceleration, no droning inside the cabin, not boy racery loud, and all while keeping the stock look(exhaust tips).

 

The cheapest option seems to be a resonator delete, and while this meets much of my criteria, it can leave a drone in the cabin around 70 mph which I don't want in a family car.

 

A custom exhaust is another solution, but it's costly and I'd be worried about the losing the stock exhaust tips. I know some have fitted AMG tips that look similar, but I want the stock tips or exact replicas. I don't want the car to look blatantly modified in any way.

 

For the Golf R, there seems to be a BCS resonator that is supposed to cancel out the drone, I don't suppose anyone has tried this on a superb?

Has anyone tried any other kind of resonator?

 

Has anyone tried anything else?

 

Really keen to get some suggestions.

 

EDIT: Forgot to add, my wife has a Mini Cooper S, and it sounds fantastic, but at cruising speeds it doesn't intrude into the cabin. I'm always disappointed when I jump from her can back into mine (exhaust note wise).

Funny thing is the 280 comes with a valved exhaust to (supposedly) provide extra noise under acceleration in Sport mode. However, unlike the same system on the R, you can't tell if it's on or off since they apparently over muffled the resonator and rear mufflers to give it more of a comfort/cruising character, makes you wonder why they bothered with it in the first place...

Now don't tell this to @Nick_H !  He's convinced all hell breaks loose when he's flooring his  

@TheBinarySheep

Why would anyone else want to hear any more or a different noise from your car as you accelerate,

why not just open your windows and listen to the noise it already makes.

that's the thing, the exhaust doesn't seems to make any noise at all, even with the windows open.

 

I'm not concerned if other people can here it, as long as I can. In fact, I'd be happy if I could fit a sound generator like on the Octavia vrs because at least it provided a nice note inside the cabin.

What you're after is not so easy or simple as it may sound. To do this right you would need a good after-market cat-back, designed and studied so as to provide the more agrresive sound under acceleration but none of the drone/boom/bad noise that you'd get from just deleting parts from the stock piping. The cheap options on this are always the worse and even some aftermarket ones sound crap so it's not something you'd get done properly (as you describe) with a couple hundred quid.

Especially since yours is a valved system, the cost rises even more unless you go down a valve delete path (might actually not be such a bad idea) but unlike the Golf R not many off-the-shelf systems out there that would match the stock tail-pipes and look so it would have to be a custom one with an exhaust specialist that knows what they're doing.

Would something like the R600 intake, elbow and a muffler delete lift it any without fiddling with the exhaust, and causing drone/boom while at motorway speeds.

Personally, i like my motors to go like stink in relative silence, as i get more entertainment value from it that way.

@TheBinarySheep

So now you have a remap to run on 95 ron & getting 99 ron requires driving places where that is sold, and you have a  poor handling car according to the other thread.

Now you care not about anti-social noise in accelerating to 60mph in residential areas within your 12 mile area.

 

Sleepers are nice where a car can speed off without drawing attention IMO.

I think you're completely missing the point.

I'm driving out of my way now to get 99 ron.

I'm getting a stiffer roll bar fitted to improve handling a little.

I want the car/exhaust to have a nice subtle note to it that I can here in the car when I'm driving (for my pleasure), that is well within legal noise limits and in a way that doesn't appear chavy and keeps the car looking and sounding as stock as possible. Which part of that is anti-social and makes the car no longer a sleeper?

I've asked for some advice/suggestions, and so far your posts have been about as helpful as a box of matches in a forest fire.

OK.

Hard really to be going places on journeys where filling stations / supermarkets are not there to fill up unless in some far flung parts of the UK.

 

Just pulling your plonker.   Your area is surely not one where boy / girl / granny and grandad boy racers annoy others just enjoying the garden with their big bore exhausts and show and no go.

Yeh this is the problem. It seems the cheapest option would be to get an anti-drone delete pipe for a golf r and have it fabricated to the fit onto the Super... and then hope it's what I'm looking for.

Or the other solution as mentioned about, change the intake, but from what I've read you don't get really much extra sound from the intake unless you go down the open cone route, and I don't like that as it is doesn't look OEM. At least the R600 intake does look OEM in a way.

Once I'm done, I'm going to get myself out there, tearing around outside of old peoples homes and bungalows causing a nuisance with my anti-social behaviour.

I run the R600 (closed air box) and there is no noise increase at all. The Cup Edition could be louder but then again that's different to exhaust noise and I don't like the open design of the Cup for a few reasons.

Not many serious alternatives to be honest for what you're after.

And a last thing, a resonated, quality after-market cat-back on these cars will not cause the sound chaos around small towns and villages that some would like to imply. There's plenty of stock exhaust systems out there today that sound 10 times louder (and to some, more annoying) than our 2.0 TSI with an aftermarket exhaust that it's ridiculous to even enter that discussion unless the subject was "hi guys I'd like to run an empty pipe from my turbo all the way to the back of the car, can you help?"    I mean Sundays can be slow all-right, but arguing over issues that don't exist and even sounding patronizing about them

I started an E63 S recently with a full Akrapovic system fitted to it. Bloody thing made me jump and i was ready for it. This thing was Anti-social just ticking over.

It was good fun for about a minute and a half, before it just became really annoying.

Just one of many examples, and I am mainly referring to systems that come on the cars from factory and have the full certification to be used on road cars like the "Sport Exhaust" option on Audi's, BMW's and Mercs.

What the OP is about has literally nothing to do with that sort of exhaust noise/level.

When I put my foot down it sounds like the gates of hell have opened !!! ( In reality when I'm parked on the drive I can hear them clicking as they open and shut .... Thats how I know they  are there but HEY !!! It's cool ... Right ? )

That is exactly it. Ideally I'd like something on-par with what's available from the factory from other manufacturers, not something that's going to shake the neighbours windows.

It seems options are limited, and maybe it's something I'll just leave for now.

 

As for the flaps on the exhaust. To me, they don't do much at all, but, if they only open at full throttle, then at that point the noise of the engine drowns any additional noise from the flaps being open. Has anyone tries jamming the flaps open or coding them so they're open, is there any difference in exhaust note lower down in the ref range where the engine noise isn't as loud?

Maybe it's possible to have the tips removed from the OEM exhaust and put onto a custom exhaust? Problem then is I'm aware that at some point I'll be getting rid of this car, so I want the option to be able to revert most of the changes back to stock fairly easily.

Im exactly like you @TheBinarySheep im also wanting to improve sound of my 280 exhaust. I believe car that's pushing close to 300bhp should make more noise at least in Sport mode. But being the type of car it is, i believe there is very fine line between improving it and spoiling it....

Been looking at cat back system from Golf R estate 7.5, the can be had for about 300quid in decent nick but not sure how labour intensive it is to make one fit, but has to be adjusted so i was told on Skoda Modderz on FB. Other than that you looking at £1000+ for half decent cat back system....

so from a reading around the interwebs, it appears that our exhausts in the 280 are pretty much the same as the golf R (strangely).

 

the flaps open up for a bit extra noise. 

 

[disclaimer - I have done this to my car, if you decide to do it to yours, its your choice]

 

if you want to open them up fulltime, you can either disconnect them via the connector on each side of the exhaust (and tape it back up), or disable via vcds. note that with the VCDS way, you need to fully power down the car before the coding takes effect.

Coding, byte 9

 

bit 2 - tick for normal operation, untick to keep them open

I'm not sure if this would be worth a shot? It might be too subtle a change though. At least you'd know they were open and then see if it makes any difference at all. I might try it for interests sake to see how it goes 😁

Save yourself a few bob by just shouting brum! brum! as you accelerate

I think that a custom exhaust is the only solution, and it will be costly.

I had to modify my stock exhaust but i wanted it to be quiet. Now it's silent at low rpm, inside you can hear it only when pushing hard.

You have to ask to a exhaust specialist what you want, it's the only way you can get the sound what you're searching for.

Is that using standard backboxes? They almost look factory.

Yes they are the OEM mufflers. Roscio only really messed with the exhaust due to his big turbo requirements not for getting extra noise   But he did end up with a little bit more sound as a bonus, as a result of the upgraded downpipe and the upgraded mid resonator, nothing annoying though he has reported.

True, actually now the sound is slightly more present, I think because of the central resonator that has settled.

Nothing relevant, indeed, maybe it's almost better now. However, it always remains silent, especially when used in D.

Am I right in thinking that an exhaust specialist could swap out the existing resonator with another one that lets a little more noise through without having a drone?

Yes. The trick is getting it right without a drone while at cruising speed.

272 also has the GPF to consider, which will mute your exhaust regardless of resonator.

I'll try and speak to an exhaust specialist and see what they say. Thankfully I've got one of the proper 280's without the GPF
