Car Chemistry CC Inserts Car Chemistry CC Inserts are a proven, lightweight solution to help reduce exhaust noise and meet decibel limits at track days and racing events. Their patented multi-disk design actively draws exhaust flow through the system, improving scavenging while lowering overall sound levels. How CC Inserts Work Unlike traditional mufflers, CC Inserts draw air through the exhaust stream when in operation. Because their function depends on heat and flow, they must be installed close to the engine. On a flow bench the inserts appear restrictive, but in real-world conditions they move substantially more air due to their patented scavenging effect. Expected Sound Reduction 2-disk insert: typically reduces noise by 3–5 dB 3-disk insert: typically reduces noise by 5–7 dB Results vary by engine configuration and exhaust design. Oversized exhaust systems may remain louder than expected because CC Inserts flow exceptionally well. In some racing applications, only a single disk is needed; you may cut down a 2-disk insert for fine tuning. Performance & Versatility CC Inserts can increase torque and horsepower by improving exhaust scavenging while reducing sound. Each insert measures 7 inches long and installs inside your header collector or exhaust tubing. They can be made removable and are fully customizable using packing material, restrictor caps, or tuning plugs. Available sizes include 2", 2.25", 2.5", 3", 3.5", 4", and 4.5" OD. Size selection is based on the outside diameter of the tube into which the insert fits. Because tubing varies by gauge and manufacturer, some applications may require minor grinding or slight tube expansion for proper fit. Sold individually. Single-exhaust systems require one insert; dual-exhaust systems require two. Important: CC Inserts are designed for closed-course and off-road use only. Performance and legality vary depending on engine and exhaust configuration, and no specific application can be guaranteed to meet all local sound requirements. CC Insert Installation Follow these guidelines to ensure proper operation and safe installation: Install the insert with the non-perforated (short) end of the center tube facing the exhaust outlet. Position the center tube opening at least 1.5" from the point where all primary tubes merge inside the collector. Trim the tube back to the first disk if needed. Secure the insert by welding, bolting with a minimum 1/4" through-bolt, or using 3/16" stainless rivets. Do not use screws. Tuning Options Restrictors & Packing: For quieter operation, you may tack weld the included restrictor (pre-drilled plug) to the front of the insert. The solid plug lets you custom-drill a smaller opening. For maximum quieting, use the restrictor on the inlet and the solid plug on the outlet. Stainless packing may be added between disks. Tube Fitment: Insert diameters are based on OD, but actual tubing ID varies. If too tight, lightly machine the disk rings. If too loose, flare the tube slightly for a snug fit. Catalytic Converters: Do not install CC Inserts ahead of catalytic converters. Always mount them downstream. Relocate any pan-evac systems after the insert. Fueling Changes: Some race engines may require leaning out the mixture by 1–2 jet sizes. This is most common on naturally aspirated engines using gasoline or alcohol. Muffler Systems: When used with an existing muffler, install the CC Insert before the tailpipe passes over the axle. Inserts are less effective when placed too far aft. Coating: The black coating is for storage protection only. It may flake or burn off during use. Safety Note: Inserts must be securely fastened. Failure to do so may result in the insert being expelled from the exhaust system, causing damage or injury.
