The Grand Rock 6″ x 48″ Aussie Reduced to 5″ O.D./O.D. Chrome Exhaust Stack (A6-48SBC) delivers distinctive Australian-inspired styling with practical fitment versatility. Produced by Grand Rock, this stack features a 6-inch outside diameter at the top that reduces to a 5-inch outside diameter at the base, making it ideal for trucks running 5-inch exhaust systems. The 48-inch height creates a tall, commanding presence, while the Aussie-style cut adds a unique, eye-catching finish that stands apart from traditional straight or miter designs.

Constructed from high-quality materials and finished in a durable chrome plating, the A6-48SBC is built to handle demanding road conditions while maintaining a brilliant, mirror-like shine.
