I used these chrome slip on tips for one season. Im getting a Cobalt muffler installed tomorrow and dont need them anymore. I took them off for the snow months because even though they are supposed to be stainless steel, the road salt and winter slush messes them up. They slide on tightly with a little help of a rubber mallet or strong palms of the hand. Im asking for $25 shipped. They add a little bit f neatness to the car. Thanks.
