Looking for a way to fix the annoying valve rattle present in some of the i30N or i20N rear mufflers but don’t want to spend $150 to do it? Here’s the solution for you. If you take your car back to Hyundai, they won’t just attempt to replace the valve, they’ll instead give you a whole new axle back. This is not just time consuming, but they’re also not really fixing the issue with the weak factory springs. Fix your exhaust sound with the upgraded Spring today
