I found a set of tips in a catalog that I think would look great. They fit our size pipes, and are 3 1/2" in diameter and 9 inches in length. Has anyone put tips on that large before? I am concerned about melting the bumper. Any thoughts would be helpful. Also, if I wanted to replace the muffler, is stock the way to go, or has 20 years of newer technology given us something better. Thank you all and HAPPY HOLIDAYS, Ross VIN 911 CA LIC "MCFLY"
