Product Description

The SLP 31067 LoudMouth II™ Bullet Muffler is a high-flow, universal performance muffler designed for exhaust systems with a 3.0" inlet and outlet. Built from polished stainless steel with a ceramic-wrapped, perforated core, this muffler delivers an aggressive exhaust tone while minimizing high-frequency drone inside the cabin. Its classic bullet-style design not only improves exhaust flow but also adds a clean performance-oriented aesthetic to custom and modular exhaust systems.

This muffler offers excellent versatility - it can be integrated into many custom exhaust builds or paired with SLP modular cat-back systems to tailor the sound and performance of a vehicle. The universal fitment means it works with various applications that use 3.0" piping and common clamp/hanger installations. Whether you're upgrading an existing system or building a custom performance exhaust, the SLP 31067 provides a deep, commanding exhaust note and reliable long-lasting construction for enthusiast-level builds.
