| CTS-V Owners have an opportunity to take that built in HP to another level with ARH's 100% U.S. made 304 S/S header system. Designed to free up some serious HP by eliminating what's arguably one of the most restrictive factory exhaust systems ever, ARH CTS-V systems will deliver the performance you'd expect, with the quality ARH is know for. The system comes with 1-7/8"or 2" primaries with 3/8" think flanges and hand ported inlets, the trademark merge collectors with scavenger spikes, a 3" x-pipe that includes ARH's 49 State Legal severe duty 200 cell metallic substrate cats and connection pipes that route back to the rear axle. The installation is simple and straight forward. Minor Fabrication is required to adapt the system to factory mufflers but everything is supplied to make the job a snap.
CTS-V Owners also now have the option to do some one-stop shopping when the need for a complete exhaust system arises. Expanding on ARH's extremely popular Header / X-Pipe system, they've now completed the system by adding their Pure Thunder Series Mufflers and 4" Double Walled Polished S/S Tips. They've also Upgraded all S/S tubing to their mufflers to 3". Manufactured entirely in the U.S., the system is built to handle over 1000 RWHP while providing a deep tone with no rasp and a great appearance. Now one of the hottest GM vehicles ever manufactured has a header system that can only make it hotter |
