Scott1967 Posted February 2, 2019 Share Posted February 2, 2019 Well I have it on good advice that my exhaust is going to need to be replaced in about six months to a year ( I’ll need a from cat system) The question is .......Do I get a Porsche switchable sport system from Porsche or should I look at an after market replacement with switchable valves? any advice would be appreciated Scott Link to comment Share on other sites More sharing options...
Porsched eggs Posted February 2, 2019 Share Posted February 2, 2019 I think it's a case of horses for courses but my 2p is bear in mind a non Porsche exhaust will stop you putting an OPC warranty on the car so if that's important to you there is only one choice. Also I have the Porsche exhaust and it's best at town speeds to be honest, and it's hardly night and day. I think the aftermarket carnewal type options will definitely give you a bigger hike in noise. On the plus side the Porsche system is never annoying and doesn't drone. 1 Link to comment Share on other sites More sharing options...
Scott1967 Posted February 2, 2019 Author Share Posted February 2, 2019 I worried about the noise from some exhausts hence thinking the switchable was a good option ive just had a K&N filter fitted during the service and was hoping I would get a little improvement in performance if I do change the exhaust as I said I’ve got 6-12months before the exhaust will need to be changed so I have time to research it Scott Link to comment Share on other sites More sharing options...

Mavrik Posted March 21, 2019 Share Posted March 21, 2019 @Scott1967 Did you do the mail order exchange thing or take a road trip to Belgium? My bro is a welder/fabricator by trade & I'm wondering if its possible to "copy" the Carnewal mod? Link to comment Share on other sites More sharing options...
Scott1967 Posted March 21, 2019 Author Share Posted March 21, 2019 I planned the road trip but my wife changed her job so she couldn’t make it therefore I mail ordered it it was £135 to remove the old one and then fit the Carnewal Link to comment Share on other sites More sharing options...

I'm assuming your old exhaust was in usable condition? 1 Link to comment Share on other sites More sharing options...

When I got mine fitted by Gert back in January I had a brief conversation with him about this, and I came away with the knowledge that he has spent a significant amount of time and money to perfect the work he carries out on the exhaust so it meets all the requirements for noise, emissions, reliability etc. I don't think it's something that can be easily replicated tbh. 1 Link to comment Share on other sites More sharing options...
Craiglm68 Posted March 22, 2019 Share Posted March 22, 2019 That's a good price for the swap over work! And the noise will evolve a bit over the first couple of hundred miles....in a good way! 1 Link to comment Share on other sites More sharing options...
Scott1967 Posted March 22, 2019 Author Share Posted March 22, 2019 My original only has 26000 on it it was a bit awkward getting the 02 seniors out apparently so yes it was in good condition 1 Link to comment Share on other sites More sharing options...
