Designed to free up some serious HP by eliminating what's arguably one of the most restrictive factory exhaust systems ever, ARH's new CTS-V system will deliver the performance you'd expect with the quality ARH is known for. The system comes with your choice of either 1-7/8" or 2" primaries with 3/8" thick flanges and hand ported inlets, their trademark merge collectors with scavenger spikes, a 3" X-pipe that includes ARH's 200 cell metallic substrate cats, and connections pipes that route back to the rear axle.
The installation is simple and straight forward. Minor fabrication is required to adapt the system to the factory mufflers but everything is supplied to make the job a snap. Now one of the hottest GM vehicles to ever hit the performance world has a header system that only makes it hotter.
