Product Description:
Hawks Motorsports is pleased to offer our clients the following 2014-2019 Chevrolet Corvette C7 6.2L LT1/LT4/LT5 3" Stainless GREEN Catted X-Pipe that connects to the OEM-style 2-3/4" exhaust, by Kooks, part number 21703300.
Once you've stepped up to Kooks long tubes, the rest of the exhaust needs to keep pace. This 3-inch X-pipe gives your C7 a serious path between the headers and factory-style rear exhaust, combining a full 3-inch system up front with the proper 2-3/4-inch OEM-style connection out back. It is the kind of setup that makes sense when you're building an LT-powered Corvette and don't want the factory rear exhaust connection to become the weak link in the system.
Kooks part number 21703300 is constructed from 304 stainless steel and features a 3-inch GREEN catted X-pipe configuration with 3-inch x 2-3/4-inch mid-pipes for connection to the OEM-style rear exhaust. This system requires compatible Kooks long tube headers and is designed for applicable C7 Corvette LT1, LT4, and LT5 applications.
