Stumps 311 Posted August 26 Does anybody know the regulations in regards to the use of side exiting Exhausts in NSW? I looking at possibly fitting twin 2.5in pipes exiting just before the driver side back wheel. As far as I know it needs to be at least 30cm from the last window or seal and 90db maximum noise...am I missing anything. Any help would greatly appreciated Share this post Link to post Share on other sites
