Double-D Exhaust Systems

Sounds Like Unrestricted Power.

• Less back pressure than all other systems tested; 64% to 76% less than original equipment systems.
• Designed with PRO/Engineer CAD software.
• Unique acoustic design eliminates in-car resonance or "drone" generated by some other systems.
• Mandrel-bent tubing eliminates restrictive "neck-downs" at bends.
• CNC-manufactured for easy, bolt-in installation without interference.
• Robotic welding is utilized to prevent leaks and enhance appearance.
• Premium grade T304 stainless steel used throughout for maximum corrosion resistance, increased ductility, and extended durability.

Callaway engineers developed the Double-D Exhaust design for the lowest possible restriction in order to provide maximum power. The unique muffler and tip configuration produces excellent sound quality: slightly louder than stock at idle and cruise to allow normal in-car conversation and much louder than stock under acceleration, with a deep powerful tone. Minimizes in-car resonance; very easy to install.

Callaway Exhaust Systems include stainless steel mufflers, polished Double-D exhaust tips, stainless steel over-axle tubes, premium quality hardware, and comprehensive instructions.
