SLP 1 3/4'' Tuned/Long Tube Headers, 1998-99.

The length of each header tube was calculated to maximize exhaust scavenging. The headers' tuned tube lengths use exhaust pulses to create a vacuum in the collector. This vacuum pulls exhaust gases out of the cylinder making more room for a fresh air/fuel charge. The more efficient exhaust scavenging lets the engine rev faster and produce more torque and horsepower. You will see increases of up to 41 horsepower and 58 lb. Ft. of torque! Equal length headers work well but, SLP tuned tube length headers are the ultimate! SLP's new headers are built with stainless steel 1 3/4" primary tubes that flow into a stainless steel, 3" collector. The headers have quality OE flanges and are completely compatible with the stock EGR, oxygen sensor and air pump systems. To connect the headers to your complete "back to the bumper" or other SLP exhaust system, SLP has designed a unique new stainless steel 3" y-pipe to work specifically with these headers. This pipe is included with the headers. To use the y-pipe you must have our optional catalytic converters (31037). NOT legal for use on pollution controlled motor vehicles.

* Convertible with automatic transmission requires kit 30054 & 30055.
