Chevrolet Silverado Exhaust Kooks

Kooks Headers and Exhaust announced the debut of a full bolt-on exhaust system for the new 2019+ Chevrolet Silverado and GMC Sierra 1500 pickup trucks – the ones based on the new General Motors T1 platform. The full Kooks system consists of headers, 49-state-legal “Green” catted Y-pipes, and cat-back exhaust. A Silverado or Sierra with this new exhaust system will be more than just a better sounding V8 pickup truck, as the kit adds 17 horsepower, and 15 lb-ft of torque on top of the stock engine. Those numbers are dyno-tested, according to Kooks.

Kooks engineers have been developing bolt-on exhaust systems for the Chevrolet Silverado and GMC Sierra for 18 years now. So it’s fair to wonder what took so long for an aftermarket exhaust authority such as Kooks to develop a bolt-on system for the T1 Chevrolet Silverado and GMC Sierra. The answer is that it all goes back to GM’s fortified cybersecurity systems, and its encrypted ECU. Included in that are the onboard diagnostic systems (OBD) on these General Motors pickup trucks. These sensors continually monitor the engines and emission control systems, including parts like the catalytic converter. Needless to say, this continues to present a major hurdle for the aftermarket.

As a result, Kooks claims that developing this bolt-on exhaust system for the 2019+ Silverado and Sierra has been the most extensive R&D project in the history of the company. The result of the time put in is that the new bolt-on system is engineered to perform without any other modifications.

We’re post a video of the new GMC Sierra and Chevrolet Silverado exhaust system when it becomes available. Below is a full pricing breakdown for the various Kooks kits:
