siddleg Posted March 20, 2018 Report Share Posted March 20, 2018 Hi I'm fairly new to boxster ownership and finding myself needing a new exhaust system who do you recommend? I'm thinking manifolds, sport cats etc but not sure who to trust as lots on eBay that seem reasonably priced then design 911 seem a bit expensive. Help thanks in advance Link to comment Share on other sites More sharing options...
Saxosim Posted March 20, 2018 Report Share Posted March 20, 2018 I haven’t tried them personally but intend too but I have heard from others on here that you can’t go far wrong with a system or backbox from Carnewal. The Carnewal GT system is really reasonable too and based on an exchange with your original back box Link to comment Share on other sites More sharing options...
edc Posted March 20, 2018 Report Share Posted March 20, 2018 They cheapy eBay manifolds are fine. Used now on both my Boxsters since 2012. Link to comment Share on other sites More sharing options...
nick_johnson Posted March 20, 2018 Report Share Posted March 20, 2018 I've got a SuperSprint Race back box on my 2001 S which sounds very nice, in time I'd like to also change cats and headers in time. It fitted onto the OEM Cats no problem. Link to comment Share on other sites More sharing options...

What type of driving do you do? Is the existing exhaust too quiet, too loud, to droney etc etc?. Link to comment Share on other sites More sharing options...
siddleg Posted March 21, 2018 Author Report Share Posted March 21, 2018 So that the headers taken care of then if the eBay one's are ok. The existing exhaust/cat is leaking bringing up a warning light so need to go. System is original to car apart from the o2 sensors. I would like to buy a full system so then it's done it's just which to get and where from main requirement is that it's not too loud. Link to comment Share on other sites More sharing options...
edc Posted March 21, 2018 Report Share Posted March 21, 2018 If you want it standard sound then get an OE Dansk replacement. Link to comment Share on other sites More sharing options...

edc Posted March 23, 2018 Report Share Posted March 23, 2018 Top gear do a valves exhaust too. Link to comment Share on other sites More sharing options...
Cunningr Posted March 24, 2018 Report Share Posted March 24, 2018 I noticed not much mention of being careful of drone. Many if the aftermarket exhaust have a drone in the cruising range between 2k to 3k rpm. I havent changed yet but I plan on doing fvd brombacher sound version, hearing good things and no drone. But pretty expensive. Link to comment Share on other sites More sharing options...
siddleg Posted May 6, 2018 Author Report Share Posted May 6, 2018 Quick update so I opted for a toyo sport s/s cat back system won on eBay and even though the mechanic who fitted it moaned and groaned about it not fitting great it sounds awesome, looks good and was good value for money so overall I'm happy with it and my original box was split at the seams. Unfortunately the engine management light has come back on so the cat must be passed it was hoping the split back box was the culprit given its throwing up post cat lambda.

RickLS7 Posted May 7, 2018 Report Share Posted May 7, 2018 Did you fit new O2 sensors? If not then one (or more) are probably knackered. Link to comment Share on other sites More sharing options...

I did renew the 02 sensor was the first thing I tried so I'm going to have the codes read again to double check before a buy a new cat from cats direct I think I spotted one £126 type approved.

I recently had a similar issue with my 2004 2.7 replaced the both O2 sensors on bank 2 but still got the CEL a few days later. It may be down to an air leak on the inlet side, check the ducting around the throttle body and the small vacuum pipes connected into the plenum before spending too much money Link to comment Share on other sites More sharing options...

I went for the same and overall I’m happy with it. You do get a slight drone around 2/3k revs but I find with the roof down it’s not as bad. The sound it makes when you open it up is more than worth it, I love it. I found it was harder to get the old back box off than fit the new back box, I found the fit very good on mine, just about to replace the exhaust manifolds next for stainless ones (I have the manifolds, just need the time to change them). I didn’t have any issues with my exhaust, I just wanted it louder?? I hope you’re enjoying the Boxster. Link to comment Share on other sites More sharing options...
