Bring your LS-powered F-body exhaust together
Your third-gen Camaro or Firebird can keep its classic appeal with an LS engine at the centre of the experience. Kooks 22312400 gives the conversion a long tube header with 1-7/8-inch 304 stainless primaries and 3-inch TORCA collectors.
SKU: 22312400
Made for the specified chassis arrangement
A BMR KM008 tubular A-arm K-member is required. The mandrel-bent primaries use 3/8-inch laser-cut round-port flanges with the factory bolt pattern, so choose the header around the actual conversion hardware.
The header fitting parts are included
PY-8024-AL gaskets, SB-B60029 header bolts and two JI-K61003 TORCA clamps are supplied. Have the engine position and exhaust alignment checked together during professional fitting.
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.
