Hawks Motorsports is pleased to offer our clients the following 2016-2019 Cadillac CTS-V LT4 6.2L 3" x OEM Competition-Only Stainless Steel Connection Pipes by Kooks, part number 23123100. These 304 stainless steel connection pipes are designed for the supercharged 6.2L LT4-powered Cadillac CTS-V and transition from a 3-inch inlet to the 2-3/4-inch OEM exhaust connection size.

If you're putting long tubes on a third-generation CTS-V and want to keep the exhaust moving without choking it down with the factory connection setup, these are the pipes that bridge the gap. The 3-inch Kooks side carries the flow out of the long tube headers before stepping down to the OEM-size outlet, making them the right piece for a serious off-road exhaust combination that continues into the factory-style rear exhaust section.

Part number 23123100 is a competition-only, non-catted connection pipe system. These pipes do not contain catalytic converters and are designed for use with compatible Kooks long tube headers.

The connection pipes are constructed from 304 stainless steel and require cutting of the stock exhaust for installation. This product is intended for competition-only applications and is not represented as legal for use on public roads or highways.
