Hi guys I’m trying to find the right exhaust mod for my ba falcon xt (non turbo). Currently My car is lowered and speed humps -bumps have damaged my front muffler. I was thinking of hotdogging my exhaust to give me the clearance but I was told that it was illegal. I was just wondering if anyone on here knows if I can do the modification without having the hassle of it being illegal. Any help will be very appreciated
