Buying Guide
The primary function of a muffler is to muffle the sound produced by the engine. The sound travels as pressure waves through the exhaust system, and the muffler’s design helps reduce these waves, producing a quieter sound. The design can also influence the exhaust note of the vehicle.
Types of Mufflers
According to Design:
- Baffle Type:Â Contains perforated tubes inside, restricting direct passage of exhaust gases. Ideal for a quieter sound.
- Chambered:Â Features inner chambers that reflect sound waves against each other. Perfect for a throaty rumble.
- Straight-Through:Â Designed for maximum airflow and horsepower. Known for minimal restriction and louder sound.
- Turbo:Â A mix of glasspack and chambered designs. They are less loud and restrictive.
According to Fit:
- Direct Fit:Â Designed to attach without modifications. Perfect for hassle-free installations.
- Universal Fit:Â Requires some modifications for fitting. They are cheaper but may not offer the same fit and finish.
According to Purpose:
- Standard or Stock:Â Fitted from the factory, designed mainly for noise reduction.
- Performance:Â Free-flowing designs that boost power and are louder than stock mufflers.
- Racing:Â Used for high horsepower applications, usually louder and designed for maximum performance.
Factors to Consider When Buying
