High Performance Mufflers

Porter Mufflers was started in 1931 by the Porter brothers in Los Angeles and for generations the same basic design has proven itself to be the best performance muffler available. When you have a product that’s just about perfect the worst thing you can do is change it so we have never felt the need to, “reinvent the wheel.”
