Headers for your larger-exhaust LS build
Match your classic LS conversion to an exhaust with 2-inch primaries and 3-1/2-inch collectors. Kooks 29302651 is the larger-collector header choice for the listed Camaro, Firebird and Nova conversion applications.
SKU: 29302651
A larger collector for the matching exhaust
The 304 stainless headers use collectors with O2 fittings. The 3-1/2-inch collector diameter is a separate choice from the primary size, so match both to your engine and intended connecting exhaust.
Set the engine position first
LS sliding engine mounts are required. Your installer should establish the engine position, then align the headers and exhaust with the steering and chassis clearances checked together.
Tuning for your exhaust upgrade
We recommend tuning with every header installation so the calibration suits your headers, complete exhaust and fuel. Talk to us to discuss tuning for your vehicle and the parts you are fitting.
