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.

Frequently Asked Questions:
Q: 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.
Q: 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.
Q: 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.
Q: What material are these headers made from? 304 natural stainless steel with full TIG-welded construction and CNC-machined flanges.
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)).
