Give your classic LS conversion a proper exhaust
An LS engine can make your classic Camaro, Firebird or Nova a car you want to use more often. Kooks 29302401 gives the conversion a purpose-made header, with 1-7/8-inch 304 stainless primaries and 3-inch merge collectors.
SKU: 29302401
Position the engine to suit the headers
LS sliding engine mounts are required. They let the installation be matched to the engine position in the classic chassis, with clearance checked around steering and suspension components.
Connections for a complete custom exhaust
The merge collectors have O2 fittings and a ball-and-socket connection. Choose the connecting exhaust around the 3-inch collectors and have the complete system aligned once the engine position is set.
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.
