I appreciate you're being light hearted here, but a 991 is probably £15 to £20k more than a similar spec 997.2, so the "spending a fortune" comment doesn't really stack up.
You could get a nice exhaust (Akra, Kline etc.), keep the stock one, revert back at sale time and sell the Akra/Kline all for waaaaaay less than a 991.
Anyway, in my experience the 991 is a rather different car compared to a 997 so it's all a bit moot anyhow.

Oh, and if you get the right exhaust it'll sound nothing like a Corsa!


One of my chums just bought a 991 S in mint condition for 50 k, one owner with 40 k on clock, full OPC history, granted it was missing the PSE but the difference isn’t 15-20 k Thumb the gap has narrowed, so on a serious note rather than spend a fortune on an exhaust I’d still be inclined to go the 991 route Dont know

My colleague recently got a 991.2 S and I was surprised at how muted it sounded. I felt like a total badass in the office garage when I fired my car up. He looked a bit deflated. Surprised

This thread has prompted me to take the car out of the garage so that I can wake up the neighbours in the morning.

Thanks guys, great advice! The akrapovic YouTube link sounds really nice.

In essence this is the type of sound I’m after...https://youtu.be/YFTmCPqssRg

Might just have a look at a 991.1 with PSE - everyone says they sound more like what the 997.1 with PSE sounded like - but seen the feedback on here suggesting it is quieter than the 997.2 which is contradictory Sad

To the poster who has H&S and wants to do the gundo hack, don’t would be my advice - my one sounded a mess after...very loud but in a ‘farty’ like way and genuinely embarrassing. It is the first time my heart has ever sank when driving a car after a small modification. I wished that I put the bypass on and not messed with the mufflers.

After have a 996 with PSE perhaps I’m being unrealistic.

I haven't heard Cargraphic, Akrapovic or Kline in person but they are very expensive although no doubt very good.
I spent slightly over £2k on an exhaust from CGR Automotive in Rotherham; it's a very well made full stainless system and I think it sounds damned fine. Have a look here: https://www.cgrautomotive.co.uk/single-post/Porsche-911-Exhaust

Just my 2p's worth, regards, Mike.


That sounds lovely!!!

Is there any drone ?

@spongebob, I'm not quite sure what your thoughts on the 991 are Scratch Chin

I once heard of a chum who ended up with a sooty tailpipe after a chance meeting with a Balmoral Green Range Rover that caught his fancy...

Be careful you don't end up the same way! wack

It's easy, but a new TVR Griffith and a 997.1 as cheap as you possibly can Smile

I know someone who knows someone who bought a Cat D 997.1 recently for £14k....... What a bargain, it is apparently perfect....

The yellow 991 in the soundbite was not stock , they just dont sound like that. As I have said exhaust note is very personal and many will be very happy with the sound of the OE exhaust , but there are also others that want a bit more aggressive note. and I have to say to my ears the custom 2k exhaust that COB has does sound good and is a decent price for what it is.

OP, my bro just got a full system done on his heavily modified RS3 by www.deutschtech.co.uk near Milton Keynes. I’m not on the VW/Audi Group scene but apparently the chap they have doing their exhausts is an artiste Thumb

That CGR system is the best I’ve heard on a 997.2.

Is it a 3.6 or 3.8? Looks like badge is just carrera not carrera S?

My car is, or was, a bone stock 3.6 Gen 2. The video on the CGR site was made by another member on here (neil911); I'm unsure whether his car is a 3.6 or 3.8 though.
The exhaust sounds really good, it's got a lovely howl at higher revs but is not silly loud at low speeds, just a muted growl. There is a tiny bit of cabin resonance in 7th gear, on the motorway, under load; that's my only criticism.
Build quality is really good (304 stainless, back purged, super clean welds) and the fit is spot on.

Is the sound on Neil’s the same as yours?

I’ll have to try and find his original thread.

Mine has a Topgear Secondary Bypass + Fabspeed Cold Air induction kit = no disappointment, sounds nice on start up, sounds even better above 4,000 rpm.
Still OK with neighbours and cats.
Not huge money about £1,000
However the Jag does sound pretty awesome agreed its on a different level.
A mate has the F-Type really likes it but now wants a 911 or Cayman

Nice problem to have though 997.2 or 991.

I felt my ears burning Laughing


My car is a Carreras S 3.8 PDK with sports chrono

Single silencer each side and yeah. Sounds like...

https://m.youtube.com/watch?v=xKBXsrxQNvk


Best mod I ever did to the car, sounds like a GT3 and gets positive comments at the super car meets Smile

CGR makes all the silencers in house, so can tailor the sound if you're not quite happy with it

As a side note I did a lot of research before working with Charlie to develop my exhaust, I requested a X pipe. Charlie's solution was to pass both sides of the exhaust together but to keep the flow path uninterrupted by crossing them over, the exhaust bends back on itself with a small opening that shares the noise but doesn't distrupt gas flow.

I think without a cross pipe, you're trying to make 2 3 cylinder engines sound good. A downfall with many competitors exhausts

That makes absolute sense, I can’t believe I hadn’t realised that myself. frustrated

A 911 with H&S still sounds somewhat better than two fiesta ecoboosts! (Maybe not quite on a par with two Triumph speed triples though)

The 997.1 with gundo sounds great, but the additional noise is the engine slowly eating itself Very Happy


H&S with PSE (unplugged) sounds great. I wouldnt want anything louder to be honest because i'm not 17 any more

Speak to the guy who does the noise monitoring at Spa, he'll confirm how good an Akrapovic is, I may have been partly responsible for the breach of the noise regs on that day as Phil and I were close together but Phil was happy to take the crown as the loudest 997 on that day.
I've got a 997.2 turbo with the Sharkwerks pipe on so not really much help here but it does sound 'mint' as they say, especially in Sport when it cracks on the change up's!
