Product Description

Please allow 14 days for ceramic coated parts.

NEW!! Fenderwell header muffler known as CC Insert. This unique design helps pull the exhaust gases through the exhaust system. CC Inserts provide a deep crisp note to any exhaust system. Developed to quiet racing exhaust systems, the Inserts provide a very light, efficient alternative to bulky mufflers. Testing has demonstrated that CC Inserts can improve low AND mid range power, even when compared to open headers. When used in street applications you gain all of the benefits of the race units with an aggressive exhaust note that hints of a full race system. 

The turn out portion is approximately 5.5" long. The portion that goes into the header is approximately 5.5" long. (1.5" of the core can be trimmed off if needed without affecting the function) Simply slide them into your header collector. Attach with the 3 bolt header flange. These baffles are so unique that they have a US Patent. They offer a great amount of versatility to dial the sound where you want it. They can be packed between each disk with a muffler packing or steel wool and each kit comes with an optional plug and restrictor cap for the center tube. Save weight, and valuable space under the car. The turnout points toward one hole on your header collector. (In most cases, down and out) Sold as a pair.

Car Chemistry, Inc. cannot guarantee that any specific application will meet the sound requirements of all municipalities or other governmental agencies. The wide variety of engine configurations and exhaust system designs preclude guaranteeing that all systems using CC Inserts will be street legal. The size is based on the outside (OD) diameter of the pipe the Inserts are to fit into. Each application will be different. Some race applications have proven satisfactory with only a single disk insert. The use of CC Inserts allows the user to custom tailor the unit for his specific application.This can increase torque and horsepower, while decreasing sound volume.


Coating service will be 14 days.


Available sizes: 2.5", 3", 3.5". Check our store for listings in your size.
