The new cat-back system from Tenneco’s DynoMax performance exhaust brand for 2011-2012 Dodge Charger/Chrysler 300C R/T 5.7L Hemi V8 cars adds horsepower and torque to the popular models. The new DynoMax exhaust system (Part no. 39518) is available now at performance retailers nationwide.
The DynoMax Charger/300C exhaust system posted a gain of 13 horsepower and 24-ft. lbs. of torque in recent dyno testing. The new system includes 2.5-in. high-quality, 409-grade, OE-style stainless steel piping for extended protection against corrosion.
This system also features a pair of stainless steel Super Turbo mufflers, a unique DynoMax design that provides a true performance tone with minimal resonation. These mufflers include exclusive, patented flow directors that channel exhaust flow and eliminate turbulence; internal flow tubes to reduce backpressure and improve flow; and fiberglass matting to help absorb unwanted resonance. Super Turbo mufflers flow up to 700 standard cubic feet per minute (SCFM).
Each system includes necessary OE-style rod hangers, six stainless steel band clamps and additional hardware plus handy, easy-to-follow installation instructions.
Covered by a limited lifetime warranty, each system is backed by an exclusive 90-day Performance and Sound Guarantee. The 90-day Performance and Sound Guarantee allows an enthusiast to try the product for 90 days. If within the first 90 days of ownership the consumer is unhappy for any reason, they can return the products for a full refund of the purchase price.
