Kdh Posted October 10, 2021 Share Posted October 10, 2021 I have a 2.7 manual with PSE and when the valves are open the sound is perfect but just slightly too quiet. I have Boxster S twin tailpipes. Are there any mods I can do in the way of sports manifolds, cats, to up the volume slightly or am I stuck with what I've got. 'Opening the windows' is not an option in Winter. Many thanks!

Andy Posted October 11, 2021 Share Posted October 11, 2021 You need to have a chat with Gert at Carnewal, loads of people on here have his conversions and having heard them in the flesh they are brilliant. http://www.carnewal.com/Exhaust 1 Link to comment Share on other sites More sharing options...
Kdh Posted October 11, 2021 Author Share Posted October 11, 2021 (edited) My current PSE system came from Gert. His standard conversions don't sound as good to my ears. I did want to ask his advice/buy some 200 cell sports cats but he doesn't answer his emails anymore. Thanks anyway Andy.
