JBA 40-301100 Universal Chambered 3" Offset/Offset Muffler 304 Stainless Steel

The JBA Performance Exhaust 40-301100 is a universal-fit, chambered-style performance muffler constructed from corrosion-resistant 304 stainless steel. With a compact 11-inch oval body measuring 11" x 9.75" x 4", this muffler is engineered for tight chassis clearances where a longer muffler body simply won't fit, making it an ideal choice for trucks and performance builds with limited undercarriage space.

The chambered internal design produces a deep, aggressive exhaust tone while managing backpressure for a refined sound character. Both the inlet and outlet are 3" offset/offset, providing versatile routing options to suit a wide variety of custom and performance exhaust configurations.

Key Features:

• 304 Stainless Steel construction for superior corrosion resistance and long-term durability
• Chambered design delivers an aggressive, throaty exhaust note
• Compact 11" oval body — the shortest in the JBA chambered muffler lineup
• Body dimensions: 11" x 9.75" x 4"
• 3" offset inlet / 3" offset outlet configuration
• Universal fitment suitable for a wide range of street and performance applications
• Backed by JBA's commitment to quality manufacturing since 1987

Whether you're building a custom exhaust system or upgrading an existing setup, the JBA 40-301100 delivers performance sound and lasting durability in a space-saving package.
