SLP's new 2010-2015 V8 Camaro 4-into-1 Long-Tube Header System features equal-length 1-3/4" main primaries flowing into 3" high flow collectors. The headers are mandrel bent 409 stainless steel and ceramic coated to keep heat in, exhaust velocity up, and under-hood temperatures down, while the rest of the system is made from high-quality stainless steel.

These headers will install onto your L99 or LS3 Camaro's engine without any modifications, not to mention ease of installation. Clearances around all wire harnesses, vacuum lines and AC lines meet or exceed factory clearances.

NOTE: Header Package does not fit Convertible models.

Best of all, SLP's complete header package netted +28HP RWHP and +27ft-lbs gains over the stock factory system at the wheels. (Gains above are with no tune on an otherwise bone stock L99 Automatic 2010-15 Camaro; don't be fooled by other power gains that include a tune). We designed our complete header packages to provide you with the most horsepower and torque possible.

Also, included in the package is a pair of 3" high flow catalyst converters, which flows into a full 3" integrated PowerFlo-X® Crossover assembly including 3" mufflers and 2.5" under-axle pipes to bolt to your LoudMouth II® axle-back exhaust system of choice. (A LoudMouth II axle-back exhaust is needed to use this full header package part #31212 or #31212S).

This header package is fully compatible with all stock emissions-control equipment and use OEM flanges for perfect fit and proper bolt retention. All necessary installation instructions and hardware are included, backed by our Lifetime Warranty.

SLP 4-into-1 Camaro Long Tube Header Package features:

  • 4-into-1 design w/3" collectors, featuring 1-3/4" equal-length primaries.
  • All mandrel bent stainless steel construction to maximize flow.
  • +28 HP RWHP and +27 ft-lbs gains over stock system.
  • Polished aluminum-ceramic thermal-barrier coating (interior and exterior surfaces) to keep heat in, exhaust velocity up, and under-hood temperatures down.
