CatalogMuffler Series › Storm Muffler Series Storm Muffler Series

In the spirit of the most powerful of storms comes Solo’s Storm muffler series. It is a combination of free flow and chambered muffler that offers you the best of both worlds. It has a deep aggressive exhaust note at rev and take off and becomes extremely quiet at cruising speed.

Characteristics:•  Beautiful deep performance tone without the annoying cabin drone
•  A combination of free flow and chambered muffler

•  The chambers kick in when you increase your speed and the sound becomes quieter
•  Absolutely no cabin drone and almost factory quiet at cruising speeds
•  The 5″ x 11″ body size is quieter than the 4″ x 9″
•  Designed for larger size engines
•  Many times, increased horse power/fuel efficiency
•  Polished stainless steel with tig welding
Typical Customers (but not limited to):•  Pick-up truck owners
•  SUV owners
•  Muscle car owners
