C8 Corvette Gains 20 RWHP With Kooks Stainless-Steel Exhaust Headers

When modding a car’s exhaust, we oftentimes think about the design of the tips or the mufflers at first. But the headers shouldn’t be taken out of the equation because their role is to help the exhaust gases escape the cylinders as easily as possible.

Headers differ from manifolds in terms of construction. The header is made up of individual tubes for each exhaust port while the manifold is a cast-iron component. The benefits of using a header instead of a manifold? Well, the former helps eliminate the back pressure of the latter because each cylinder gets its own pipe.

With that out of the way, let’s focus on what the aftermarket is currently developing for the C8 Corvette Stingray. Kooks Headers and Exhaust is almost done with their stainless-steel, TIG-welded exhaust headers for the mid-engine sports car, and customers will be treated to a couple of options in the first instance. More to the point, the American company will offer for sale 1-7/8-inch and 2.0-inch tubes.

Pricing isn’t available at the time of writing, but chances are these babies won’t differ too much from the C7 Corvette Stingray. Depending on the spec, you're looking at $1,335 for the 1-7/8-inch by 3.0-inch headers and $1,430 for the 2-inch by 3.0-inch headers. Kooks uses aircraft-quality T304 stainless steel, and the original purchaser further benefits from a limited lifetime warranty for the headers.

A performance shop from Mooresville - PCM of NC - has dynoed a Z51 prototype headers, and as the headline implies, the LT2 sends 20 more horsepower at the rear wheels as well as 26 more pound-feet of torque "with no tuning.” PCM would also like to highlight that the “new platform is exciting.”

For reference, the Z51 in the photo gallery dyno'd 439 RWHP with the stock headers, meaning that we're currently talking about 459 ponies. It’s also worth remembering the LT2 is the entry-level engine in the C8 Corvette lineup – if you can call it as such. Here’s hope the LT6 flat-plane crankshaft V8 in the Z06 will be that bit more exciting thanks to a higher redline and the kind of sound that would make the GT350 blush in awe.
