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 2" 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:
- 2" 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
- Longtube Header Design — Maximum scavenging efficiency vs. shorty or mid-length headers
- Dyno Proven — 25+ RWHP gain on LS3 and L99 applications
- Compatible with LS3, L99, ZL1, and 6.2L Engines
Note: Band clamps are only included when the off-road connection pipe upgrade is selected.
