I can guarantee that will still sound louder than stock.

According to TD, the stock cat back with catless header is not much louder than full stock. The cat back on the stock system reduces the volume by a lot.

The super resonated cat back is much louder than stock on my car with no rasp, so it may be ideal for you. If you're running without the secondary cat it should be louder than mine still, even if it's 'double resonated'.

As matrixprotein says, if you have the opportunity to hear some in the flesh that is ideal. That mistake cost me a lot of money on the HKS single exit haha.

It's very difficult to have a perfect solution because we all have different tastes. You will just have to try around and see.

@likaito love the "maximum laudness" aspect mate, and I'll absolutely take your infos in mind, but if it gets so raspy I would stick to something less loud but more enjoyable (for my taste of course).
 
@BigBoyBananas the idea of a super resonated one is pretty much what I was thinking to go these days. As I menaged to understand in my yt/forums researches maybe some EL headers will mostly fit my taste and according to what @matrixprotein was saying the hks double resonated frontpipe will be a great option to add for a "less raspy catless". 
But actually the -EL headers/double resonated frontpipe/super resonated catback- combo will yes sound really deep and "true" but way to quiet, maybe even quieter than stock. 
So as a possible final solution swapping the super resonated catback with the mxp comp rs catback MAYBE will take me to the sound that I'm looking for. The EL headers and the double resonated frontpipe will keep the raspyness down, while the less resonated catback will make it a bit more loud.
The other option I was considering was the Greddy evolution gt catback which according to what people say is one of the loudest catback out there. Maybe fitting some big big resonator somwhere in the centrepipe will do the trick.
Or the last option is to dont give a shit about (little) raspiness and get the Greddy with the HKS dual resonated frontpipe.
Meanwhile I'll wait for your opinions, I'm so confused and unsure in all of that, and I dont wanna spend thousands of euro in something that I dont like.
Btw really thanks to both of you guys for the help, really appreciate it!

Hello LxrdVbz,

I'm going to make a post about this separately at some point but I think it's pretty hard to avoid rasp on this car with free flowing systems.

*It might be different for a turbo car though, my car is NA*

I swapped the headers for decat Tuning Developments EL and then installed a resonated single exit HKS cat-back WITH a silencer section. 

So:
- Retaining one CAT
- supposedly the quieter cat back option

I thought it might actually be too quiet but no, it was supper loud. Around 3k rpm rasped like fuck. At low revs it was nice, if a bit boomy (not good for motorways), and at high revs it screamed (very nice). But in the middle it was horrible, and for my own tastes too loud across the board.

Speaking to Mike at TD @Mike@TD.co.uk big part of the problem was single exit and small silencer section. They offer a resonated dual exit and a super resonated dual exit. These have a huge silencer section at the back similar to OEM, and a large resonator in the centre pipe. According to mike, the resonated one still rasps a bit in the mid range. The super resonated one is the only one that doesn't rasp with a catless header.

I've gone super resonated and it's great for me but probably waaayyy too quiet for what you are describing. In short I'm not sure it's going to be easy getting a raspless noise as well as loud volume.

Good luck though, I'll be following to see what others say.

I would advise against using videos as a guide for noise too as I thought the HKS sounded amazing on you tube and the TD zorst too quiet.
 

Hey mate,
I'm running a Tomei UEL Manifold, Decat front pipe, stock resonator and Berk muffler delete.
That's pretty much a straight pipe. I would recommend leaving the stock resonator because a res delete would be really really raspy.
This set up is pretty much as loud as you can get imo, and is really deep and bassy. Love it. Probs one of the loudest set ups in the UK haha

Sorry I mean non resonated catback. But that will be ridiculously loud. I personally wouldnt go that loud. If you are turbo charging in the near future then you can as a turbo will make the exhaust quieter but if you're going to keep it NA a while, then I wouldnt but each to their own.

Any reputable brand is fine I would think. Just not milltek

Get a hks front pipe then go resonated exhaust. And get a decat manifold. That will be loud like a train
