later Although they don't fit 100% perfectly, the only gaps can be millimeters wide. I can handle it for someone whose only job is to get pounded by rocks and snow. They're also half the price of OEM mufflers and pretty easy to install. 3 bolts on each wheel. Update. They were worn for about 6 months and one behind the driver's side has broken and is hanging down on the right. I'm taking off one star because I've never had a breakdown before and it annoys me to have to order another set of 4 to replace a broken part. Spare parts for the rest of the wheels I guess.
