Spinjim Posted June 6, 2017 Report Share Posted June 6, 2017 Started my 987 this morning and it sounded like a hole/crack in the exhaust. drove to work and it's cleared, sounded normal ? No loss of power or go any ideas ? Jim Link to comment Share on other sites More sharing options...
Andy Mac Posted June 6, 2017 Report Share Posted June 6, 2017 The rear flanges fail - as do the manifold joints - wonder if it's only small - sounds bad when cold - and as soon as its warm it is creating a seal again? Hopefully you can get it up in the air somewhere and get it checked over soon / and it's something minor. Link to comment Share on other sites More sharing options...
Ash_Bournemouth Posted June 8, 2017 Report Share Posted June 8, 2017 Hiya. I have the same problem with my 2005 2.7 Boxster. It sounds like its blowing when cold, but clears up later when the engine is warm. Took it into JMG Porsche who using some form of smoke test, diagnosed most of the joints leaking when cold. Exhaust itself looks old, so I think I need to replace the complete system. Just trying to find a reasonable priced complete system for my car.

Jason986S Posted June 8, 2017 Report Share Posted June 8, 2017 It's possibly cheaper to go new aftermarket than new OEM, but it's your call. They definitely can quieten down any leaks when blowing and warmed up. Dunno if the gaskets or metal expands or the exhaust particuls get bigger.

I wouldn't assume the whole lot needs replacing just because the joints leak. Is there obvious serious corrosion on the actual exhaust? A complete set of new joints and OE gaskets could well have it sorted, unless you want a different exhaust and are using man maths to justify it?

Spinjim Posted June 8, 2017 Author Report Share Posted June 8, 2017 Managed to get mine to the garage today, as suspected both joints are blowing. Im probably going to find a nice not too noisy back box to replace the OEM system which looks fairly old. Which one to go for ? Jim Link to comment Share on other sites More sharing options...

I think there is an option to sort it out, but all the joints look rusty and was trying to balance the labour cost on fixing versus replacing the complete system. I would be happy with the standard exhaust if it can be fixed. Maybe I should ask JMG for a quote. I just feel the sound of a blowing exhaust lets down the drive of the car. If anyone can recommend a supplier of complete exhaust system that is reasonably priced I would be grateful Link to comment Share on other sites More sharing options...

Spinjim Posted June 15, 2017 Author Report Share Posted June 15, 2017 Carnewal arrived today? Fitted over the weekend, so ready Monday Jim Link to comment Share on other sites More sharing options...
wardpaa Posted June 22, 2017 Report Share Posted June 22, 2017 Hope the bolts come off the flanges. Horrible job to drill out as they are splined studs pressed in at the factory with classic Porsche spec corrosion added in. Link to comment Share on other sites More sharing options...
Boxstercol Posted June 24, 2017 Report Share Posted June 24, 2017 Think mine may be suffering the same as mine always sounds much louder at start up, which joints were leaking & how did you tell? Cheers. Link to comment Share on other sites More sharing options...

Spinjim Posted June 24, 2017 Author Report Share Posted June 24, 2017 Carnewal exhaust arrived and not happy One side pipe is bent and exhaust dented and cracked, general condition poor. Advised to return to sender by garage who I have known for over 15 years and lives in the same village as me. 'New exhaust needed Jim Link to comment Share on other sites More sharing options...
Ash_Bournemouth Posted June 25, 2017 Report Share Posted June 25, 2017 I have my car in at JMG Porsche to have the system resealed and the joints redone. Fingers crossed it will be OK. They offer a fixed price menu cost for an exhaust reseal. Link to comment Share on other sites More sharing options...
andygo Posted June 28, 2017 Report Share Posted June 28, 2017 Surprised at the Carnewal issue. I went there personally and had my back boxes swapped out. Mine came from a car that had lived it's life in Bahrain, so were almost like new. I looked into stainless systems, but from anectdotal evidence suffer from boom and resonance. If i was going to swap the headers and integrated cats I'd buy them from Porsche - they will do them for £750 per side (ouch) but cheaper than Design 911 for the same thing. I feel that a complete stainless system could drag you into the Corsa chav brigade which isn't appropriate IMHO Link to comment Share on other sites More sharing options...

The garage cut the old steel bolts off the flange joint and replaced them with stainless steel ones . Quick 30 min job. Link to comment Share on other sites More sharing options...
