The factory exhaust manifolds on your 4th Gen Camaro Z28 or Firebird are one of the first restrictions holding back your Gen 2 LT1. Speed Engineering's 1-3/4" longtube headers are a direct-fit, dyno-proven upgrade that frees up exhaust flow, improves throttle response, and delivers over 20 rear-wheel horsepower over stock. Built from 304 natural stainless steel with mandrel-bent primary tubes, CNC-machined flanges, and full TIG-welded construction.
⚠️ Important Note: Some earlier LT heads have a wider bolt spread. These headers measure 17-3/8" from front center bolt hole to rear center bolt hole. Verify your cylinder head bolt spacing before ordering.

FAQ
Will these headers fit all LT1 head configurations?
Some earlier Gen 2 LT heads have a wider bolt spread than standard. These headers measure 17-3/8" from front center bolt hole to rear center bolt hole. Verify your cylinder head bolt spacing before ordering to ensure proper fitment.
How much horsepower do these headers add?
Speed Engineering's 1-3/4" longtube headers are dyno proven to add over 20 rear-wheel horsepower on 1993–1997 Camaro and Firebird Gen 2 LT1 applications compared to stock exhaust manifolds.
Do these headers work on a Gen 5 LT1 (C7 Corvette, 5th Gen Camaro)?
No. These headers are designed specifically for the Gen 2 LT1 5.7L engine found in 1993–1997 Camaro Z28/SS and Firebird/Trans Am. They are not compatible with the Gen 5 LT1 engine found in the C7 Corvette or 6th Gen Camaro.
What material are these headers made from?
304 natural stainless steel with full TIG-welded construction and CNC-machined flanges.
Are these headers street legal?
