Shown here is the difference between the stock exhaust manifold and the SLP 1 3/4-inch long tube header. A quick visual indicates that we are on our way to better e.t.'s. Once the SLP header is bolted in place it's torqued to 22 lb-ft. It's critical that the instructions be followed carefully. SLP includes a generous amount of heat sleeve that needs to be applied to the wiring harness on the passenger side. Due to tight tolerances, the harness will get hot and melt if this precautionary measure is not taken. The passenger side is now complete.
