First off, modifications done before the DC Sports headers, Cantrell intake system, K&N filter, Comptech exhaust.
I heard a lot about how everyone thought that headers were not beneficial to 97+'s but the dyno results show that they do help ! Not as much as on earlier models though (of course).
Anyhow, the headers didnt change peak numbers much, but it did change the overall power levels between 3-8 hp in many different areas across the board. Also, this dyno graph shows elapsed time across the power range, and you can see that after adding headers, the elapsed time across the rpm range was cut shorter by nearly a quarter of a second. So its now taking less time to reach redline than before.
Intake and muffler -= blue line
Intake, muffler, headers - red line
Now for those of you whod like to see what the comptech muffler did, take a look at this dyno graph. Here we have cantrell intake duct with filter, which is the lowest line (blue line), then we have the comptech muffler line (red line), and on top which is the dc sports header line (green line). Suprisingly enough, the muffler added more power than headers.
Hope everyone enjoys the dyno graphs that I scanned in, and I hope this puts some of you 97+ Nsx owners at ease wether to buy, or not to buy headers.
Overall, with intake&filter, headers and muffler ive gained close to 18 hp at the wheels, and 15 lbs of torque. The car sounds really good now, still somewhat conservative, and its made the car even more fun to drive now ! Im very pleased with the results.

18hp with only IE is awesome.
