The three chamber mufflers are typically used on tow vehicles and SUVs where interior sound level is a factor. These three chamber designs keep the interior sound level down and reduce the exterior sound level, with the same tone and performance as the smaller one and two chamber designs. Three chambered mufflers will add additional chambers with tuning tubes to help cancel out those frequencies. Drone is that sound resonance inside the vehicle that can be described as a constant hum when driving at part throttle. These models will also have interior drone. One and two chamber models will be aggressive inside and outside of the vehicle. Chambered mufflers have a raspy tone to them. Because of the lack of packing material, chambered mufflers do not get louder over time.
This collision cancels out certain sound frequencies without the need for packing or absorption material. The aggressive mufflers will not only be louder on the outside, but louder inside the vehicle as well and often have a noticeable drone when driving at part throttle.Ĭhambered mufflers use deflectors inside the muffler to split the soundwaves and direct them back into themselves on the backside of the deflectors. The moderate and mild mufflers will give you a good performance tone when accelerating on the outside of the vehicle, while keeping the sound level more in check on the inside of the vehicle. These mufflers will offer the same performance benefits as the more aggressive mufflers, but they will also control the overall sound level better.ĭo you want to hear the muffler all the time, or just when accelerating?
These mufflers will help control the interior sound level better than the aggressive mufflers during long drives or when towing a trailer.
Smaller displacement engines will sound less high pitched and buzzy when a more moderate or mild muffler is used.įor daily drivers and vehicles used for towing, we typically recommend a moderate or mild muffler. On large displacement and high horsepower engines, larger mufflers will control sound better. Vehicles with large cabin areas like SUVs or hatchbacks can be more susceptible to interior sound, or drone, when an aggressive muffler is chosen.Įngine size and power output have a big effect on the sound level. Check the area where you will be mounting the muffler first to make sure you have enough room for the muffler you decide to go with. The chassis type and layout of the vehicle can limit the choices you have in mufflers. What type of vehicle are you choosing a muffler for?
