1970-1981 F-Body header notes

The mid-length header uses a ball and socket collector, while the long tubes use a slip on collector.
The guide says both header styles clear the factory A/C box, power steering box and power brakes on a second gen car.
Header transmission list: TH350, TH400, Muncie, 700R4, T-56, 4L60E, 4L65E, 4L80E, 6L80, 6L90 and TR6060.
BRP recommends high mount A/C and alternator/power steering brackets for this body.
The headers assume a floor shifter; column shift linkage has to be modified.

1970-1981 F-Body LS exhaust FAQ

What LS headers does BRP sell for a 1970-1981 Camaro?

Two 1-7/8 inch ceramic coated headers, a long tube and a mid-length, both on the parent F-Body swap page. This subcategory carries the clamps, reducers and bolts.

What collector do the second gen F-Body headers use?

Two kinds, by the guide: ball and socket on the mid-length, slip on for the long tubes.

Will the headers clear power brakes and A/C on a 1978 Trans Am?

The guide says all of its 1970-1981 F-Body headers clear the factory A/C box, power steering box and power brakes.

Can I keep a column shifter in a 1970-1981 Firebird with these headers?

Only with changes. The guide says the headers are designed around a floor shifter, and column shift linkage will need modifications.
