You get what you pay for
I always thought that statement was not accurate, as you surely can find deals on expensive products. When a deal was presented to me, in the form of corvette headers, I jumped on it. The install and fit is great, and they also sounded the part. My thoughts were they are only bent pipes, how much engineering could possibly go into these? or in the event they are copies, then the previous time spent on engineering tasks will transfer over. They’re only pipes…
Flash forward to my car sitting at the starting line of a 1/4 mile drag strip, 20 passes previously in that day, and not 1 pass can match last years best (without headers). Now jump forward a few more weeks to the present day. The car is sitting on the dyno @ New Era Performance Parts, getting it’s ECU tuned. First run yields less power, it must need some fuel or spark. Second run yields less torque [then last year] and a gain of 4 horsepower. Piss poor, so let the car cool down and we will go for one for run on the dyno. The final run comes and goes, just like my hopes of a positive outcome from the header purchase. Overall the car gained some power, but nothing even in the double digits. Non Z06 owners are having better luck, maybe someone will want a used set.
