Boxsum Posted February 18, 2023 Report Share Posted February 18, 2023 Hi With a lot of exhaust talk going on has anyone on here done the crios mod? What size holes and does it affect emissions? Are you happy with the results? Quote Link to comment Share on other sites More sharing options...
½cwt Posted February 18, 2023 Report Share Posted February 18, 2023 (edited) There was someone who wrote up on here a while ago. IIRC he found 10mm was too small and enlarged it in steps. Put 'crios' in a search on here and you will turn up quite a few results and discussions. Edited February 18, 2023 by ½cwt 1 Quote Link to comment Share on other sites More sharing options...
jonogt6 Posted February 18, 2023 Report Share Posted February 18, 2023 It should really be called "belting a large hole in the muffler mod" its that primitive. Quote Link to comment Share on other sites More sharing options...

Not well regarded then? Haven’t really read all the exhaust mod threads on here so to cut to the chase what’s the best way to make the 986 sound a bit more like it should other than desnorkel ? ie is there an ultimate rear silencer ?

edc Posted February 18, 2023 Report Share Posted February 18, 2023 In the exhaust sounds thread there is a guy who did various sized holes with sound clip. Quote Link to comment Share on other sites More sharing options...
Terryg Posted February 18, 2023 Report Share Posted February 18, 2023 I did it prior to doing a bypass, its ok, but the bypass is way better. Quote Link to comment Share on other sites More sharing options...
