    I 100% can attest to this. My copra pops and bangs like mad for about 10-15 minutes at most then all of a sudden goes silent, not even a peep. My solution was to go back into automatic mode for a while and it seemed to help but the pops were certainly not as prominent.

    My Cupra 300 pops and bangs while driving almosf nonstop. If I rev it too much while stationary it stops after a while. I wondered why too and never got a definitive answer. A guy on a local meet told me it’s due to safety reasons regarding the engine which seems kinda logical.

    A month or so on and it's still the same. Any one else got this issue with a 290 Copra?

    it must be the Copper Badges that cause this as my new 290 which has the silver (build date missed the copper) pops and bangs happily for ever after

    Mine is an MY19 build without copper like yours and it stops.

    It’s not. That’s a Cupra with copper badges. Really annoys me

    Meanwhile my 66 plate manual 290 makes no pops or bangs in sport or cupra mode, so you should be grateful for your 15 minutes of fun [B)]

    Seriously though, I do wonder if my car has some software issue that's preventing the pops and bangs when in those modes.

    You'll hate that MY18 Cupras (without copper) but built to MY19 spec are called Frankencupras then.

    Test drove a 290 today with 15 miles on the clock. Got a few small pops out of it but after reading about the exhausts, I wouldn't expect a pop or a bang consistently before 4,000 miles.

    Interestingly, my current FR, the sound on that, as in the engine sound and exhaust sound didn't start to get decent until after about 15,000 miles. You would never get a pop or a bang out of it though.

    I honestly couldn't say what might be causing that.

    Question; who here actually HAS done a res delete? Or with the copper ones is it the new GPF style exhaust? It would be interesting to see if the res delete cures this or if it is something in the software etc that physically stops it? Does the copper have exhaust valves? If so are they closing after a while? If so can do you something (coding probably) to keep them open?

    Think it’s been investigated before to see if there is valves in the exhaust. I think the conclusion was that there isn’t. There is however a sound actuator. I don’t know how that works but if it’s like on the GTI UP then there is a portal in the cockpit to the engine bag that opens to allow more sound through rather than anything software based or in the exhaust itself.

    it does only pop above 2.5-3k revs
    I have done a Res Delete on a new 290 (mines missed the copper badging). the GPF is still in place. Yes, its not as loud as the previous 300. with the GPF you get no drone after carrying out the res delete as you do in the 300. I have now done over 7k (around 4k with the res delete) miles and I get some serious popping and some nice bangs on hard acceleration. I did get them without the res delete however they are much more enhanced now. There are no valves on the Cupra exhaust, i cant really comment if it will bring your popping back as i have never experienced mine stopping. all i can say is i would get the Zaustworkx pipe for £65 off ebay and get someone to fit it for about £30. Either way it will sound better than it currently does, pops or not

    No valves and the sound actuator is just a bad that vibrates below the window to give it fake noise, it's not linked to the engine/engine noise in anyway

    Stargate portal style? :p

    The UP GTI still uses a body/structure vibration system, same as pretty much all VAG cars. But the UP vibrates up the A pillars instead of the rear of the engine bay.

    I still don’t loose any sound on my car after driving in sport for the whole day. I can even hammer it, pushing past the kick down, in Comfort and get enough external sound?:confused:

    No delete of any sort, 5k ish miles (which on cold start and standing ticking over in general, is a lot throatier now)
