Headers as above with catalysts. Metallic substrate catalysts are utilized. The front catalyst connections are a slip fit.
On a 400 crankshaft hp engine, the catalysts will reduce horse power by about 4. On a 500 crankshaft hp engine, the catalysts will reduce horse power by about 10. An engine with this exhaust system can pass an emissions test.
The cost for a header installation with catalysts: '90 - '92 $2847.
The cost for a header installation with catalysts: '93 - '95 $3002.
AIR tubes can be added to the headers. The tubes are a flush fit to the inside of the headers, so there is no restriction to the exhaust flow. The cost is $380 for the tubes + $95 labor to connect them to the car.
