Heartthrob Velocity Series Mufflers
Double-wrapped welded aluminized mufflers with two baffles and one center v-baffle (most configurations). The double-wrapped shell helps to give a quieter sound than single-wrapped performance mufflers. Mufflers are not reversible, body sizes are 5-1/2" x 11" oval, or 4" x 9" oval. The 5-1/2" x 11" oval mufflers are shaped like our HPM turbo mufflers on the outside, but should be used when you are looking for a slight increase in noise and a higher exhaust flow. This muffler has a much lower level of resonance and drone in the cab when compared to other straight through performance mufflers. It is loud upon accelleration, but quiet at speed. This is due to the double-wrapped shell, which is virtually non-existent on performance mufflers from our competition.
