My 2015 Nissan Versa sedan was due for state inspection this month and it just so happened my daughter mentioned it was "loud lately". This car is basically used only by her for college and work. It's got about 51K on the ticker. Well she wasn't making it up that it was LOUD. I really couldn't get a good look under it because we've got about 2ft of snow and the temps are in the teens, but the flange between the center pipe and rear muffler was rotted completely away. Wound up being about $550 from a local shop to replace the full cat back system. I could have done it myself for under $300 with parts from the Rock or whatnot, but dreaded even attempting it this time of year. Man those parts are pricey for something that looks like it's for a Briggs and Stratton engine. Just venting like an old rusted exhaust because I haven't owned a vehicle long enough to need exhaust work in like 30yrs! I guess I was due.
