Each offers varying levels of performance enhancement and sound modification. I had to determine what I wanted in terms of sound and power before making a choice.

Sound Quality

Sound was a significant factor for me in choosing a 3 inch stainless exhaust. I wanted a deeper, more aggressive tone without being overly loud. I discovered that different muffler designs can drastically change the sound. I listened to various setups and decided on the sound that best matched my preferences.
