Scutch0 Posted March 19, 2017 Share Posted March 19, 2017 So I've got a kakimoto cat back on my n/a which is a lot of fun, but truthfully is way too loud for where I live, so I have to run an exhaust bung until I'm round the corner then I usuallly take it out, or I leave it in for long journeys. Well it seems my exhaust is protesting to the idea as in the last two months the bolts have come loose and it's fired 3 of them out never to be seen again! The last was a apexi 'active' bung. Does anyone have one of these apexi one lying about? Because i found it to be pretty good, but if anyone's go any tips of keeping them in, I'm open to ideas! I've used nilock nuts both times but the plastic just melts away which I'm assuming is why they've come loose! Link to comment Share on other sites More sharing options...
Nic Posted March 19, 2017 Share Posted March 19, 2017 Do a search for 'heat resistant lock nuts', you could also use some thread lock and a sprung washer. Have you considered swapping the exhaust or getting an additional silencer welded in? Link to comment Share on other sites More sharing options...
Scutch0 Posted March 19, 2017 Author Share Posted March 19, 2017 I've been using shake proof & spring washers, didn't want to use threadlock though as I do take it out from time to time. Yeah I'm considering getting the centre resonator replaced with a box, or get one of this electric cutout valves fitted with a silencer etc. Link to comment Share on other sites More sharing options...
