Construction & Design

Constructed from premium 304-grade stainless steel, the Redline Catback Exhaust guarantees exceptional corrosion resistance and long-lasting durability. All components are precision TIG welded at Stainless Works’ state-of-the-art facility in Streetsboro, Ohio, ensuring a perfect fit and outstanding craftsmanship.

The polished quad 4" tips not only enhance the aggressive rear appearance of the Dodge Challenger but are also designed to withstand the rigors of daily driving and high-performance use. The custom dual turbo mufflers and carefully tuned X-pipe geometry deliver an aggressive exhaust note while minimizing cabin drone for a comfortable driving experience.

This feature offers versatile sound control to suit any driving condition, making it an excellent choice for enthusiasts who want both performance and adaptability.
