SilverRocket Titanium Ultralight Race Pipe 13.9kg Lighter. 15HP Stronger. Pure Racing Sound. This product fits the following cars: Porsche 718 GT4 RS/ Boxster Spyder Porsche 718 GT4 RS Clubsport/Leichtbau The Lightest Exhaust In The World For The Porsche GT4 RS Designed specifically for demanding racetrack use, where power-to-weight is everything. Ultra-lightweight design to reduce vehicle weight as much as possible Exceptional durability to withstand intense race conditions. Distinctive RSR-style, high-energy race car sound. Optimized rear underbody clearance for the upcoming SR high-downforce diffuser Developed through relentless testing and fine-tuned across real race miles for elite performance. This ultra-light titanium pipe delivers massive weight savings and an incredible sound upgrade. Constructed from high-grade titanium, the SilverRocket Race Pipe weighs just 3,200 grams—cutting an incredible 13.9 kilograms off your GT4 RS. This minimalist, one-piece design not only reduces weight dramatically but also improves structural integrity and heat resistance under extreme conditions. Race-Validated Power Gains Thanks to its streamlined architecture and optimized airflow path, the SR Race Pipe delivers a significant boost of 15 horsepower over the stock muffler. Its proprietary X-Cross airflow collision and outlet narrowing design enhances exhaust velocity, producing the razor-sharp, high-pitched tone reminiscent of the legendary Porsche RSR race car. Track-Ready Fitment and Compatibility The overall height at the rear is lifted by 4cm to accommodate the upcoming SR high-downforce diffuser, ensuring compatibility with future aerodynamic upgrades. Precision-engineered to fit seamlessly with the Porsche GT4 RS factory tailpipe, it also works flawlessly with OEM headers and over-axle pipes—without triggering a check engine light. Durability Built for Endurance Equipped with SilverRocket’s innovative Flatbed Fixing Mechanism, this pipe minimizes vibration stress on high-load circuits, dramatically extending its service life in extreme racing environments. Material: Aerospace-grade titanium Weight: 3.2 kg (13.9 kg lighter than OEM!) Power Gain: +15 HP over stock Exhaust Note: High-pitched RSR-inspired tone Fitment: OEM tailpipe compatible, works with OEM header & OAP Ride Height: +4CM clearance at rear for diffuser compatibility Will this trigger a CEL?No. When installed with OEM headers and over-axle pipes, the SR Race Pipe does not trigger the check engine light. Can I use the factory tailpipe?Yes. The original Porsche GT4 RS tailpipe fits directly with no modification. Is this suitable for street use?This product is engineered for racing use only and may not comply with emissions regulations in certain regions. This ultra-light titanium pipe delivers massive weight savings and an incredible sound upgrade.

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.
