16-24 Camaro SS/ZL1 1-7/8th" Long Tube Header & Mid-Pipe Kit - Speed Engineering

FITS 2016-2024 CAMARO ( LT1, SS & ZL1 MODELS )

DESCRIPTION:

Take your Camaro’s exhaust performance to the next level with the Speed Engineering Long Tube Header & 3” Mid-Pipe Kit (Part #25-1046 & 25-1047), engineered for 2016–2024 Chevrolet Camaro LT1, SS & ZL1 models. This complete exhaust upgrade package combines 1-7/8” long tube headers with a full 3” mid-pipe system, delivering maximum exhaust flow from the cylinder heads all the way to your axle-back exhaust.

The 25-1046 long tube headers feature mandrel bent 1-7/8” port-matched primaries feeding into a 3” collector, designed to reduce backpressure and improve exhaust scavenging. Paired with the 25-1047 3” mid-pipe kit, this system connects directly to the 3” header collectors and runs all the way to your factory or aftermarket axle-back exhaust, creating a true high-flow exhaust pathway.

When properly tuned, this complete setup is capable of delivering 25+ rear-wheel horsepower gains, improved throttle response, and a significantly more aggressive exhaust tone. Built with CNC-machined flanges and durable construction, this system is engineered to handle the performance demands of both naturally aspirated LT1 and supercharged LT4 applications.

If you're serious about maximizing airflow and power, this complete long tube header and 3” mid-pipe kit provides a full exhaust solution that transforms your Camaro’s performance and sound.

Optional Parts:

• Standard Graphite vs Premium Multi-Layer Gaskets - We highly recommend using these upgraded muti-layered steel gaskets as they prevent potential future exhaust leaks.
• Spark Plug Wires - It is required to run aftermarket spark plug wires, due to size, shape and heat generated from aftermarket headers. We recommend running Speed's 10" wires to keep the spark plug wire taught, especially during heavy acceleration from the engine rocking back and forth.
• Spark Plug Wire Boots - Highly recommended to prevent the spark plug wire from resting on the header and burning through. These protect the wire with a 6" slip on design and are heat rated up to 1200°
• O2 Sensor Extension Harnesses - Required for installation of aftermarket headers due to the relocation of the primary O2 sensor bung. 

IMPORTANT NOTES:

• Convertibles require rear support bars to either be removed, or the rear connection pipes dented for proper clearance.
