SLP's new Hemi headers were originally developed for the SRT8 LX cars. They fit like a glove on the new Challenger and offer factory ground clearance and impressive power gains. The header kit features OEM-quality O2 sensor extension harnesses. After the 409 stainless headers, the high-flow cats and exhaust are made from 304 stainless and feature a lifetime warrantee. This header system will hook up to the stock exhaust and to any of the SLP after cats exhaust systems.
