1999 Pontiac Trans Am SLP Performance Parts Test - Trans Slam
|
SLP's 400HP Pac includes everything we previously installed and tested (350 and 375HP Pacs) plus the company's tuned-length, long-tube, stainless steel headers and cool 400HP PerformancePac fender badges. The headers are ceramic-coated inside and out for extra-long life and will look good for years. Included is a power-matched, 3-inch Y-pipe. Also shown and required to connect the headers to the Y-pipe are the high-flow catalytic converters. View Related Article
