Heart Throb Race Muffler. These racing mufflers by heartthrob are shaped like a glass pack body with an aluminized shell, 6" body length, spiral louvered core, one-piece shell design, packed with high-temp fiber glass. The heartthrob race muffler with the turn out will help with sound control more so than the muffler without the turn out end. These mufflers flow very well, and provide a minimum amount of sound control, and are not recommended for street use. They must be welded to your exhaust pipe, and are made of aluminized steel. 6019430 and 6019435 have six discs inside, are more restrictive, but quieter, unpacked, designed mostly for circle track racing.
