Muffler Loud Mouth II 3in Bullet-Type (each)

The SLP Performance Muffler Loud Mouth II 3in Bullet-Type is purpose-built for automotive enthusiasts seeking a balance between aggressive exhaust tone and proven durability. Designed for street performance applications, this polished stainless-steel muffler delivers the signature SLP sound character that serious mechanics and tuners have trusted for decades. Whether you're upgrading a street truck, muscle car, or performance sedan, the Loud Mouth II transforms your exhaust note while maintaining reliable backpressure management across the RPM band.

This bullet-type design features a 3-inch center inlet and outlet, paired with a 4-inch diameter body and 18.25-inch length, engineered to fit modern three-inch exhaust systems without compromise. The polished stainless-steel construction resists corrosion and thermal degradation, critical for long-term reliability under high-temperature exhaust conditions. The compact 5.9-pound weight minimizes unsprung mass while the bullet profile reduces overall underbody intrusion—ideal for ground clearance-sensitive platforms. The acoustic chambers inside are tuned to reduce drone at cruising RPM while amplifying mid-range resonance during acceleration, a hallmark of SLP's engineering philosophy.

Installation requires a standard three-inch exhaust system with compatible flanges and hangers; most applications bolt directly to existing mid-pipe or cat-back assemblies without modification. Buyers familiar with bolt-on exhaust upgrades will appreciate the straightforward fitment and the absence of welding requirements. This muffler performs best when paired with a full cat-back system or high-flow cat, allowing proper scavenging and minimizing backpressure. The polished finish requires minimal maintenance but benefits from occasional cleaning to maintain its showroom appearance in engine bays and under-vehicle visibility.
