Were you guys able to run dyno plots to redline with the race and sport headers? I know there was something cobbled together using MPH instead of RPM, but it would be good to have accurate, finished graphs that go beyond the 6900 RPM plots posted here in the forum and on your website. I expect this data will help customers compare your products to others in the marketplace.
Looks like there is some power loss at the very top end? A separate but additional concern is that the gains you measured appear to be much less than advertised by the vendor.
No power loss at the top end... Just 5 hp more over the stock set up.....however the numbers are different from what advertised by the vendor... But it's normal from my experience��

Not trying to bash you or any vendor, but you are saying that it's normal that a vendor exaggerates it's HP gains by manipulating data? Seems like dynos should show similar gains in the real world.

Pretty cool video! Btw, where is that road? Now I "need" to go drive there.
We are not here to exaggerate gains, and use a very accurate and consistant dynojet in an enclosed facility that we keep temperatures as close as possible between runs. A different car on a different dyno under different conditions may show different dyno results. Lots of variables come into play. We have seen stock GT4s/Spyders vary by 10-15hp from factory, it's just how these cars are. We have numerous GT4/Spyder owners running these headers throughout the forum loving the results

I trust your data. I do not have your set-up but a similar package and it makes a big difference.
I did mine in increments and will say the the Headers and Exhaust makes the biggest difference. Adding the tune and Plenum/TB smooths things out but gives you that 6000 rpm boost to redline. In otherwards - the Headers help you more in low to midrange punch where one will notice the difference the most
Correct... But also at higher rpm you will find a little improvement ... 5 hp in my case... With warranty expired i'll tune my ECU and i hope in better top end gains

Pretty good amount of potential with an ECU tune. Do you have a tuning solution yet? Our in house protuner is Very skilled utilizing the COBB Accessport to tune remotely anywhere in the world. Would love to get you set up with him.
We have a batch of Sport and Race Headers going through fabrication that should be done in the next two weeks. If anyone would be interested in putting their name on a set give me a shout!
