Traditional Exhaust Stack

West Coast Curve

Muscular Style

Muscular new style from the heart of West Coast tradition speaking of everything custom and chrome. Highly suited to Monster Set ups™ the West Coast Curve looks awesome in the big bore sizes. The compact, well rounded shape is ideal on shorter stacks and its profile blends well with modern truck shapes. A top stack all round...the West Coast Curve goes there time and time again...
