The Kooks Headers 31324200 is a cat-back exhaust system engineered from 304-grade stainless steel for enhanced durability and sound. The system features 3-inch diameter piping, including an X-pipe and Kooks Oval Race Mufflers, culminating in dual 4-inch polished slash-cut exhaust tips. Installation requires no welding, and the system utilizes factory rubber exhaust insulators. The estimated installation time is 2 hours, with a difficulty level rated as medium, suggesting advanced mechanical skills are needed. Important fitment notes: This cat-back exhaust system is specifically designed for the 2008-2014 Dodge Challenger SRT-8 models with 6.1L or 6.4L HEMI engines. It will *not* fit the Dodge Charger, Magnum, or 300 models when used with stock manifolds and cats. If headers are not used, it will not fit Charger, Magnum, or 300. Kooks Headers and Exhaust has been a leader in the high-performance exhaust industry for over 50 years, with all products handcrafted in the USA. This system is backed by a Limited Lifetime Warranty to the original purchaser, and every product is dyno and race tested.
