The factory exhaust manifolds on your 6th Gen Camaro SS or ZL1 are one of the first restrictions holding back your LT1 or LT4. Speed Engineering's 2" longtube headers are a direct-fit, dyno-proven upgrade — mandrel bent, TIG-welded, and CNC-machined from 304 natural stainless steel for maximum exhaust flow and over 25 rear-wheel horsepower over stock. Speed Engineering X-pipe kit is required for installation and sold separately.
Features:
- Full 2" Port-Matched Primary Tubes — Maximum flow from cylinder head to collector for aggressive LT1/LT4 performance
- 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
- Longtube Header Design — Maximum scavenging efficiency vs. shorty or mid-length headers
- Standard Graphite Manifold Gaskets Included
- Dyno Proven — 25+ RWHP gain on 6th Gen Camaro applications
- Compatible with 6.2L LT1 and LT4 Engines

Frequently Asked Questions:
Q: Is an X-pipe included with these headers? No. These are headers only. The Speed Engineering X-pipe kit is required for proper installation and is sold separately.
Q: What is the difference between these headers and the 2" full kit (25-1061)? The full kit includes these headers plus the Speed Engineering X-pipe, header bolts, MLS gaskets, and O₂ extension harnesses. These headers include just the headers themselves. Choose the full kit for an all-in-one purchase; choose headers only if you already have or plan to source the X-pipe separately.
Q: What is the difference between these 2" headers and the 1-7/8" headers (25-1046) for this platform? The primary tube diameter is the key difference. The 2" headers deliver maximum exhaust flow for more aggressive builds with supporting modifications such as a cam, heads, or forced induction. The 1-7/8" headers are a strong choice for most street and performance builds across a broader RPM range.
Q: How much horsepower do these headers add? Speed Engineering's 2" longtube headers are dyno proven to add over 25 rear-wheel horsepower on 6th Gen Camaro SS and ZL1 applications compared to stock exhaust manifolds.
Q: What engines are these headers compatible with? These headers are compatible with the 6.2L LT1 found in the 2016–2024 Camaro SS and the 6.2L LT4 found in the 2017–2024 Camaro ZL1.
Q: What material are these headers made from? 304 natural stainless steel with full TIG-welded construction and CNC-machined flanges.
Q: Are gaskets included? Yes. Standard graphite manifold gaskets are included.
Q: 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)).
