Bought this exhaust about 8 months ago it provides a deeper and louder tone than stock but I’ve recently purchased a full exhaust for this car and I don’t have use for it anymore. Nothing wrong with the muffler or any piping. I will clean the outside of the mufflers and tips and clean around the bracket where it bolts on as well as the inside of the exhaust tips. Legit easy bolt on exhaust just use the factory bolts and bracket or buy new bolts and brackets if you want. And then just put it on the hangers. Very simple takes about 15-25 mins to install.
