i notice that cat cover in front of my daewoo fell off and its starting to get louder is it easy to replace it ?

joe|||www.autopartswarehouse.com/shop_parts/ca鈥?. You are looking at $250-300. They are easy to replace. Cut the pipe in front and just behind. Measure the piping to replace the front cat with regular pipe. You need the rear one. OR, you can cut the old one out, and replace it with a new one. NOT CHEAP! Either way, the work is easy, about 30 mins.|||If its getting louder you have an exhaust leak.If under 80.000 miles take back to dealer and have fixed for free.
