Seems like a better deal since it increases HP 4x more than the z51 does .

The dyno results for the stock Vette was 439 RWHP. Most other dynos come in at 455-460. Add 20 hp and you are where most others are pure stock. I smell a rat.

The O/P was a tester for the system, if you scroll down the forum, you'll see more info:

Not buying a huge increase for the headers, maybe for the cats, but the stock headers appear to be very good.

It was 5 for the headers and 15 for the cats.

Did you speak with them or see a graph (or other data) with just the headers, or is it your estimate?

Yeah not sure what else people want to know. The data speaks for itself. Car was broken in as per GM recommendations so 439 is what I got. Now with 1200 miles on the car I will be happy to see if any changes from the 580 miles on the car when the headers and cats were installed.
