GM A-Body cars went through a transformation in 1978, and although GM re-designated rear-wheel drive A-Body models as G-Bodies beginning in 1982, the platform remained relatively unchanged until 1988. The 1978-88 A and G-Body segment contains some of the more iconic muscle cars of that era, making them prime candidates for an LS swap.

Hedman Hedders has been building exhaust headers in the USA since 1954, and their extensive experience shows in the construction of these 1-3/4" diameter, mid-length LS swap headers, designed specifically for installing the reliable, late-model powerplant into 1978-87 Caballero, Cutlass, El Camino, Grand Prix, and Regal, or 1978-88 Monte Carlo models.

Built from mild steel material and handcrafted in Hedman's Whittier, California manufacturing plant, these headers come complete with gaskets, small head header bolts, and exhaust collector adapter for attaching the headers to a 2-1/2 in. exhaust system. They have a durable, satin black ceramic-metallic finish to keep underhood temperatures down, increase exhaust speed to help with scavenging, and look good great at the same time. Also available with Hedman's HTC polished silver ceramic-metallic finish, or uncoated.

As with all Hedman Hedders, these headers are backed by a limited lifetime warranty, and the coating is covered for a full 5 years.

To ensure proper fit, we recommend the use of Trans-Dapt's engine and transmission swap mounts designed for you with these headers.

Who Is Hedman Hedders?

Hedman Hedders is an exhaust system manufacturer that began as a one-man shop in 1954. Bob Hedman, the founder of Hedman Hedders, sold his sought-after exhaust tubes to fellow racers participating in the salt flats of the Mojave Desert. But what he did not realize is that, what started out as a side hustle to earn a few dollars to support his racing hobby, turned into one of the premier header manufacturers in the world.

Choice Of Champions

Hedman Hedders are popular both in the racing and street marketplaces. Initially, his product was only intended for drag racers, but as word spread quickly, Hedman Hedders became the brand of choice among racing’s elite engine builder and racers in different racing disciplines. It is used by some of the biggest names such as Warren Johnson, Don Garlits, Shirley Muldowney, the BIGFOOT Racing Team, and the IROC series.

The company constantly reshapes itself to create products that would continuously adapt to the fast-changing automotive trends. It is also designed to meet environmental requirements and uses the most advanced and latest technology to ensure that its products perform at their optimum.
