ARH 2009-2015 Cadillac CTS-V Long Tube Headers with Catted or Non-Catted X-Pipe

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" thick 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.

X-Pipe can be optioned with ARH severe duty 300-cell cats or G-Sport high-flow 400-cell cats (recommended for those making 650+ HP) or non-catted x-pipe.
