Fitting a Porsche Sports Exhaust

[800]

Have finally got round to getting a PSE only to find all of the local specialists booked up 'till September. :eek:

Anyone know of anyone who could fit one for me next week?
Or, is it a possible DIY job? (obviously borrowing a lift)

ps. I'm not fitting the switch, but does the exhaust need any fettling to get around not fitting the switch?

[the prof]

easy job. basic tools only required, as it is a simple swap over of the silencers.

try searching on the www.renntech.org website, as i'm sure they have a diy section.

how much was the exhaust if u dont mind me asking ?

£1200

sorry to sound stupid, but what does the switch do if fitted with a sports exhaust?

[verysideways]

IIRC there is a sort of bypass valve - if the switch is in position "A" you have a quiet exhaust, if you flick it to position "B" then the valve opens and you have a sporty exhaust note.

thanks, new to porsche ownership, have a c2 996 early 98 model...so trying to learn bits and pieces...

But to retro-fit the switch on a pre-2002 car is time consuming and hence costly. So, I presume one can fix the bypass valve in the 'noisy' position???

you presume correct -most people who retro fit do this as its 1 hr labour vs 7+ hours labour (switch is also linked to ECU as valves are rpm-linked)

I mean seriously if you had a sports exhaust how often would you press the "quiet" button?

Well I'm fortunate enough to have a factory fit SE on my 996 C4S. I may not have specified it in my requirements at the time, just thinking of it as a "nice to have", but I would definitely do so now - it is super. Whilst i understand the financial and aggravation issues of retro fitting the switch, is it worth pointing out when it is useful? I use mine in two circumstances.
1. As I leave the house most mornings early, it is used to placate SWMBO and the neighbours until I have got 200 yds down the road when it gets switched off again.
2. IMHO of even more value is its use when passing horses (and their riders!)We live in a country area, and having ridden horses I can confirm that when consideration is shown it gives a good impression of driver and car. I make a point of switching out the exhaust and passing very wide and very slowly.

Not necessarily.....I'm in the middle of fitting my new silencers to my 98 C2....EVERYTHING in terms of brackets and straps is rusted to feck....rear bumper has to come off, along with heat shields.

It is easy, providing everything comes off easily (in which case a couple of hours for newbie), but the studs on the side of the silencers that bolt to the frame on the side of the engine are very diff to get to, esp the lower ones, and if the nuts round-off, as they did with me, then it's a devils own job, potentially meaning removal of headers to get to it easier.

Also, beware.....the kit you buy as Porsche OE, comes with the latest style mounting plates/brackets....the studs (3 on each silencer) are a different layout to a 1998 model...ask me how I know!....If you get the old ones off without shearing studs or without cutting, then you unbolt them from old silencers and re-use on new ones....if they are damaged, as mine were, you have to ensure whoever you buy them from supplies you with the 1998 style hanging brackets not 99-> style (1998 model has part numbers 996.111.227.02 and 996.111.228.02, in case you need to know!)

...by the way, none of this potential re-use of parts is mentioned in the PDF instructions which are Porsche documents, which I found on RennList....nor, it seems, has anyone mentioned this before (not that I've seen, anyway).

I also intend using the switch for same reasons as above, you can avoid the 45kph cutout by simply not wiring up a certain wire in the supplied harness, but havent got that far yet, so will post more when I know!

can't think of a nicer sounding alarm call

Thanks for the info. I've been doing a bit of searching on Renntec and found some really useful stuff. However, I can imagine that the reality on a 5 year old car can be another matter! I can only hope that my OPC have provided the fitting brackets for a 2000 car.
Have a weekend of fiddling with a mechanic friend, keeping my fingers crossed.

If you do a DIY job it may be worth using an oxy flame on your nuts - to get them cherry red and easier to remove without snapping studs of course. Awaiting correction by techies and medical practitioners
