Thank you. I've got ramps at work, just wanted some background info before I set one of the technicians loose on it tomorrow.

It's 1" 1/4. Apparently gets the best sound.

That's odd, mine's 1" (which is as Porsche intended on a 996.1) and yours looks way bigger from here Dont know

But then you are running 3.8 vs my 3.4.

Of course there is no equivalent design for the 997 to compare directly (the later 3.6 996 and all 997 boxes use a corner nipple bypass AKA FisterD (or Fister 2, Fister 1 is the other US name for the Gundo hack, back in the day, the same bridge method 993 bypasses were also called LPMM - Leland Pate Muffler Mod).

I just wondered where you had heard the Gundo name before, it implied you had predominantly read US sites over UK or European sites. In the same way, if you had said you took the "elevator" I would be interested whether you were born there, lived there or were putting on some strange affectation and why?

Anyway, prepare yourself for an aural treat that is borderline criminal Porsche don't offer as standard (and on the ever more muted water cooleds, is essential to get back to that flat six rumble and bellow of old).

It's definitely 1" 1/4, or so the fabricator told me - I'll measure it on Tuesday just to confirm! Which is the size Ive been told works best on the 997.

Oh and I've heard mine is bigger than yours........ Very Happy

Been delayed on fitted it as the exhaust sleeve bolts were corroded, so have ordered new ones my my local OPC, but I now won't get them ill weds. Can't wait for the noise.

It's on! And I like it.

Just to clarify it's 1 1/4" internal diameter, it is loud though, but not too much, as only comparing it with it's pre 'hacked' sound. It sounds quite raw almost GT3ish, if that makes sense.

I will try and get some sound clips over the weekend.

I guess it depends who did it, how, with what materials and the cost.

Have a look here if you need more info:

Have had them sat round after I had them done and then realised that my warranty would be impacted so can't use em for 18 months. Make us an offer and happy to consider

Finally decided I'm going in for the plunge and going to do the PSE hack. From various searches on here It seems the best place to get it done is Hayward and Scott in Essex.

Are there any other options to consider? Preferably closer to Surrey.

Anyone been to H&S and had this done with any comments, suggestions?

Also what's the best pipe size to go for?

Any videos of sound clips of before and after?

Basically if anyone has any more information or experience on this then please post, all feedback and replies will be welcomed and read.

Many Thanks

Hopefully this will answer many q's. (the PSE is basically the same between 996 and 997):

(also, do a search for "Hayward Scott" and "Haywood Scott" - with Search for all terms option - "&" won't work)

Thanks for the link GT4 Smile

£250 sound very reasonable to me, did you take off the mufflers yourself or did you just hand them the car and come back later?

Antonio, how much did it cost you, if you dont mind me asking.

Thanks
