Lonewolfgjp Posted August 1, 2018 Report Share Posted August 1, 2018 Completely different ? Although I did read a thread online where someone fitted the 987 system to the 986 with lots of modifications ? Link to comment Share on other sites More sharing options...

Lonewolfgjp Posted August 1, 2018 Report Share Posted August 1, 2018 There aren’t that many sports exhaust options for the 987, and most are quite expensive. If you’re own exhaust is in decent condition the Carnewal is a good option and he offers an exchange for your old back box. I bought the valved Topgear cat back for my 987s and it was very good ? A bit louder than standard with the valves closed but proper sports car loud with the valves open. The wife always thought it sounded a bit loud but I thought it sounded fantastic. My new car has the factory sports exhaust which sounds nice but definitely a bit tamer than the Topgear exhaust. I think the Carnewal modded back box is more in line with the factory sports exhaust sound ? Link to comment Share on other sites More sharing options...
red rocket Posted August 2, 2018 Report Share Posted August 2, 2018 Having had problems with the non-valved Topgear i would go for Carnewal. Loads of people have it and they all seem to love it. Link to comment Share on other sites More sharing options...
