Sports Exhausts for 993
Discussion
I've got the Cargraphic back boxes on mine. They have an excellent sound - no resonance or boominess on normal throttle openings, but a vicious rasping on full throttle rising to a howl at high revs.
I previously had some Fabspeed Supercups on it, which were utterly mental. I have them for sale, but as you didn't specify that you wanted a car that could drown out a 4.5 Cerbera on straight pipes then I doubt they're for you.
Verysideways has the RSR pipes and speaks highly of them - these are also very cost effective on an exchange basis from Carnewal.
You may also like to attack the airbox with some power tools, a few well placed holes will improve the induction noise.
I have no experience of remaps, I went the whole 9 yards and supercharged mine.

He's right you know, the RSR's are great!
The new owner of my C2 picks the car up tonight, if you are anywhere near Berkshire this is the time to come and listen! Be warned, the C2 sounds ten times better than my turbo...
He will be taking the car back to London with him, but i think i may have converted a few more to the RSR "dark side" so they'll be around i'm sure.
Best part about the RSR boxes? Gert sends you them and you fit them - if you don't like 'em after a week or two, send them back. The end.
Oh, but you won't be sending them back. Trust me, they're perfect (especially with a motorsound airbox - or the strategic holes mentioned by cyber)

Strategic holes!! thats what you need...I had some drilled in the airbox..about 12 of them..in the top right hand corner (each about 1/2" diameter). It improves the sound no-end. You might not need any super-duper boxes as a result..and saves you money!!
Try it first..then decide. Have fun..

I have a correctly drilled 993 airbox...i would happily swap for a standard version if anyone needs more sound and doesn't want the hassle of drilling one themselves.
Club,
are you reverting, or is it a spare airbox. If it's the former, may I ask why?, is their a downside to a drilled airbox?
IIRC the standard Porsche airbox has markings for the locations of the holes on the interior of the box, so it's a simple task to drill them in the 'right' place (i.e. where the Motorsound holes are).
I don't think there is any downside other than extra induction noise - the only usual issue with induction mods is pulling warm air rather than cold, and there will be little difference between the air at the end or the side of the 993 airbox...
Airbox alone ain't enough though - you need some decent exhausts
The OEM exhausts are also *very* heavy, so decent lightweight pipes can also make a small improvement to performance. Don't expect sports exhausts and filters to give any BHP on the 993, they don't.

Yesterday the assitant pro at the golf club came up to me to say what a superb sound they made and what make were they as his sister has a 993 2S and was looking for something that gave the car a bit of much needed character in the sound department. I also have drilled out the airbox.
Had the RSR's on my last 993 and are an improvement on the OEM, but the Maxflo's get it right

Reverting back if anything...I currently have the holes taped over and sent my RSR exhausts back.
On the occasions I track the car I want to make sure I come well inside the circuits noise limits to avoid being sent home.
The 993 is an RS version, with the reduced soundproofing it sounds pleasant enough.
Hi
If I choose to drill holes in the airbox to improve induction sound (using the pre-marked positions), what diameter holes should I drill ?
I am also debating an exhaust change, prob to RSR's.
Is the conversion a reasonably straight fwd DIY job (considering rusted bolts etc) ?
Cheers

Hi Nick,
Yeah, you get new bolts for the "onions" from gert when you get the RSR's - take the back wheels off, put the car on stands, make sure you coat the old bolts in WD40, go make a cup of tea, and you'll be done an hour later.
Allow 2 hours for the job if you're reasonably competent, 3 hours if you understand what a spanner and screwdriver can do.

I vote for a drilled airbox and RSR's. My youngest daughter said the car sounds as though it is going fast even when it is standing still, and my sister-in-law looked at it and said "Is there something wrong with it? why does it sound like that? They don't normally sound like that do they?" Bless 
Definitely RSRs and drilled airbox. It is a diy - very easy. I ended up dremelling the old bolts off.
You may want to check the state of your heat shields too (2 screws for each, again v easy). I got new ones from Gert as mine were well rusted.
Take the opportunity to add exhaust tips too!!
I have a spare (undrilled) box if anyone wants to try the drilling and be able to revert back to a non drilled (although I cant see that happening!).

^^ Good point - and perhaps not immediately obvious unless you know 911s well...
The 993 back boxes are separate from the tail pipes, so if you buy some nice shiny stainless sports boxes (e.g. from Fabspeed or Cargraphic) or some exchange boxes from Carnewal (RSRs) then you'll either have to bolt on your original tailpipes or fork out for some fancy ones.
Cargraphic do a nice broad range of tailpipes from single ovals to duals, etc. - not a plug as no doubt other companies do them. Of course you can do the super stealth and use your old tail pipes.
If you want lairy looking pipes jutting out the back of your 993 then it'll cost extra. Equally, if you only want flash looking exhausts without the extra noise, then you can simply swap the tail pipes
Just pointing this out, the PH 993 forum club massive already know this, obviously
