The factory exhaust manifolds on your C6 Corvette are leaving power on the table. 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. Engineered with improved ground clearance over competitors, making them an especially strong choice for lowered C6 builds across Base, Z06, and ZR1 trims.
Built from 304 natural stainless steel with mandrel-bent primary tubes, CNC-machined flanges, merge spikes, and full TIG-welded construction.
⚠️ Important Installation Notes:
- Speed Engineering X-pipe kit is required for proper installation — sold separately
- Base/GS models use the 3" X-pipe with 2.75" reducers to factory exhaust
- Z06 models use the 3" X-pipe with 3" connection
- 4L60E transmission — true dual exhaust does NOT work with early 4L60 transmissions. Modification to the passenger side tube is required for 4L60E fitment. Compatible with 6 speed automatic and manual transmissions without modification
- Rear exiting exhaust kit will NOT work with vehicles equipped with a differential cooler
Features:
- 2" Primary Tubes with Merge Spike — 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
- Improved Ground Clearance Over Competitors — Engineered with extra clearance, ideal for lowered C6 builds
- Longtube Header Design — Maximum scavenging efficiency vs. shorty or mid-length headers
- Standard Graphite Manifold Gaskets Included
- Dyno Proven — 25+ RWHP gain on C6 Corvette applications
- Compatible with 6.0L LS2/LS6 and 6.2L LS3/LS7 Engines
- V8 Engines Only

FAQ
How much horsepower do these headers add to a C6 Corvette?
Speed Engineering's 2" longtube headers are dyno proven to add over 25 rear-wheel horsepower on C6 Corvette LS2, LS3, LS6, and LS7 applications compared to stock exhaust manifolds.
Do I need an X-pipe kit to install these headers?
Yes. Speed Engineering's X-pipe kit is required for proper installation. Base and GS models use the 3" X-pipe with 2.75" reducers to factory exhaust. Z06 models use the 3" X-pipe with a 3" connection. The X-pipe is sold separately.
Will these work with my 4L60E transmission?
True dual exhaust does not work with early 4L60 transmissions without modification. A modification to the passenger side tube is required for 4L60E fitment. These headers work with 6 speed automatic and manual transmissions without modification.
Will the rear exiting exhaust kit work on my C6?
The rear exiting exhaust kit will NOT work with vehicles equipped with a differential cooler.
Are these headers good for lowered C6 Corvettes?
Yes. Speed Engineering specifically engineered these headers with improved ground clearance compared to competitors, making them a strong choice for lowered C6 builds.
What engines are these headers compatible with?
These headers are compatible with the 6.0L LS2/LS6, 6.2L LS3/LS9, and 7.0L LS7 engines found in 2005–2013 C6 Corvette Base, Z06, and ZR1 models.
What material are these headers made from?
304 natural stainless steel with full TIG-welded construction, CNC-machined flanges, and merge spikes.
Are gaskets included?
Yes. Standard graphite manifold gaskets are included with the headers.
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)).
