The factory exhaust manifolds on your 5th Gen Camaro SS or ZL1 are one of the first restrictions standing between you and more power. Speed Engineering's 1-7/8" longtube headers are a direct-fit, dyno-proven upgrade that frees up exhaust flow, improves throttle response, and delivers over 25 rear-wheel horsepower over stock.
Built from 304 natural stainless steel with mandrel-bent primary tubes, CNC-machined port-matched flanges, and full TIG-welded construction — engineered to fit right and built to last.
Features:
- 1-7/8" Port-Matched Primary Tubes — Full-diameter flow from cylinder head to collector for maximum exhaust scavenging
- 3" Collector — Optimized for strong low-to-mid RPM torque
- Mandrel Bent Tubing — Consistent tube diameter through every bend; no crimping, no restriction
- CNC Machined Flanges — Precision fit at the head and collector for a leak-free seal
- 304 Natural Stainless Steel Construction — Corrosion resistant, heat tolerant, and built to last

FAQ
How much horsepower do these headers add to a 5th Gen Camaro?
Speed Engineering's 1-7/8" longtube headers are dyno proven to add over 25 rear-wheel horsepower on LS3 and L99 equipped 2010–2015 Camaro SS and ZL1 applications compared to stock exhaust manifolds.
What is the difference between the 1-7/8" and 2" longtube headers for the 5th Gen Camaro?
The primary tube diameter is the key difference. The 1-7/8" headers are the more traditional size and work well across a broad RPM range, while the 2" headers are better suited for higher RPM builds with more aggressive modifications. For most street and mild performance builds the 1-7/8" tubes are the more common choice.
Do band clamps come included with these headers?
Band clamps are only included when the off-road connection pipe upgrade is selected at the time of purchase. They are not included with the headers alone.
What engines are these headers compatible with?
These headers are compatible with the LS3, L99, ZL1, and 6.2L engines found in 2010–2015 Chevrolet Camaro SS and ZL1 models.
What size are the primary tubes?
These headers feature full 1-7/8" port-matched primary tubes with a 3" collector.
What material are these headers made from?
304 natural stainless steel with full TIG-welded construction and CNC-machined port-matched flanges for a precise, durable, leak-free fit.
Are these headers street legal?
No. These are race-only headers intended for closed-course competition use only. Installation on a street-driven vehicle may violate the Clean Air Act (42 U.S.C. 7522(a)(3)).
