Does this mean you did NOT use an aftermarket catback or modified exhaust? You ran the DC race header and factory catback?"The following dyno chart is for an 06 Civic Si with a DC Sports header, Injen intake and Hondata Heatshield gasket. The only change from the green to the blue dyno run was a change from the stock ECU program to the Hondata reflash."
Also, I noticed that it says you ran an Injen intake? Was it a short ram? I don't see a CAI on their website, so I assume it was the Injen short ram. But then on the other dyno chart below it says you used an AEM CAI.
If you could answer these questions for me I would very greatly appreciate it and it would help me make a decision, thanks!
