This is a great muffler for those looking to keep quiet down low but like a little bark once in a while! From idle to 1/3 throttle you can barely tell this is not a stock muffler. In the mid-range you will notice a nice deep tone a little louder than stock. When you hit higher RPM this muffler has an exceptionally good tone without being obnoxious. This muffler has special thermal barrier and internal packing that keeps it very cool on the outside. You can typically put your hand right on the muffler after running the motor. It helps reduce under hood heat and won't melt any side panels. Another key benefit is the horsepower gain! 2-3 HP over stock depending on model. This very durable muffler is made from stainless steel and available in either our stealth black or ceramic chrome finish.
