Long Tube Headers
Long Tube Headers utilize 2" primary pipes and 3" collectors. The material is 304 stainless steel. They are ceramic coated on the outside and the inside. The ceramic coating is polished. The engine is tuned for the headers.
The typical performance improvement for a 400 crankshaft hp engine is +15 ft. lbs. torque and +25 horse power.
The cost for a complete installation. '90 - '92 $2398.
The cost for a complete installation. '93 - '95 $2334.
The installation above is for off-road use only
Catalysts can be custom fitted to the long tube headers. High quality metallic substrate catalysts are utilized. The front catalyst connections are a slip fit. The rear connection on the right is an OE type fit. The rear connection on the left side is a three bolt flange. The connection on the left requires shortening the left exhaust system pipe.
On a 400 crankshaft hp engine, the catalysts will reduce horse power by about 4. On a 500 chp 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. '93 - '95 $2783.
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 $325 for the tubes + $90 labor to connect them to the car.
