Valves make a massive differenceOk, thanks guys I'll have a look at some point soon. To be honest, I'm not sure it's actually drone, it's just quite loud on 'throttle'... on the motorway in a high gear, it's pretty quiet, so I think it's probably how it should be, just wasn't expecting it to be quite so damn loud. I think it's because the valves are set to open permanently...
Yep. I want to do so too! Until the next post talks about too loud and too much drone .So I've just been to Torqueflow Exhausts and had this done to my FL S3 saloon and here's my thoughts:
As others have said, this is what the car should come like as stock. The burbles on start up are so much more pronounced and when you need power, the noise is exactly as it should be. When you're cruising it's quiet and non-offensive unlike a new exhaust system would be.
I've done about 30 miles since having it done this afternoon (a mix of roads) and there's no drone at all. I think this is attributable to the 7 speed s tronic box and the fact my valves function as stock.
Personally, I won't be getting my valves coded open as that would be too much noise too often for what I'm after. Putting it in sport Once in a while will then be a nice alternative (I'm a sucker for tunnels!)
All in all, if you're on the fence like I was- take the plunge and do it.
Just out of curiosity, does this affect the warranty at all? I assume it will void the warranty on the exhaust system which is to be expected, but I assume the rest of the car remains ok? After all, the de-res is an OEM option in some parts of the world.
It is an OEM aftermarket upgrade in the USA but I think they have an extra cat or something over there so from stock it's much quieter than Europe's.Precisely this- the exhaust warranty will likely be voided (arguably from the cat back only) however the rest of the car will be fine.
Why Audi don't make this an OEM action in the UK is beyond me- would be a nice little earner for them clearly given the amount of us who have had it done!
I'm having a problem shutting my valves with Carista beta - as in it doesn't work. The drone is too much for me at motorway speeds! Anyone know how to shut them again?
It seems to work after the car has been left for a while. Confirmed by cleaning my exhaust. Only 2 dirty pipes nowI'm having a problem shutting my valves with Carista beta - as in it doesn't work. The drone is too much for me at motorway speeds! Anyone know how to shut them again?
Not really what I wanted to hear as I’ve had the BCS powervalve res delete earmarked for the new year purely because I don’t want any drone! Is yours a manual or auto?I think it's because the valves are set to open in fairness... need to try it with them closed. It was okay on the way to work this morning actually, had it in Auto mode and seems much better. Put it back in full Dynamic and it's a ****** animal again... almost embarrassing... almost. I'm undecided if I like it, but I've kept the old silencer, so I can always get it put back on if I decide it's not for me. Gonna give it a few weeks and see.
Closing the valves does really change it from too loud to just right in my opinion. If it's too loud then you'll have to go the resonated backbox optionNot really what I wanted to hear as I’ve had the BCS powervalve res delete earmarked for the new year purely because I don’t want any drone!

Had mine done last week, but I'm having it put back to standard again. There's a lot of intrusive drone at part throttle (worse in higher gears) and it's very loud on cold start. Too much for me (strange, as I came from a Focus ST mk2 which was also deresonated and then 3inch Scorpion systemed!) I may look at a Milltek resonated system in the future though as I've heard it's slightly louder than standard...
must be looking at max £20 to get a pre bought pipe fitted then, will have to phone around.I paid £70 to have a straight pipe fabricated and fitted (with sleeves, not weld).
4 months on and still loving it. Does drone when slow accelerating on mway between 2.5-3.5k revs - doesn't bother me too much.
Really that bad? do you have the flaps open, as i currently do and thinking will need to close them again if i get my res delete thrown on this week.
I've had my pipe sitting to go on, almost sold it as was put off but heard one the other day and WOW! what was i waiting for.....
How much should i be paying to get this fitted at a garage? must be a 20min job, no?
