I have narrowed it down to DC Sports or Crawford. My question is has anyone installed either one and then done a dyno run? What were the gains? I know alot of people install some different mods and do a reflash and then dyno but I am curious as to the diff in gains from the headers alone, and how DC compares to Crawford. Not what they CLAIM but actual dyno #s from the people I trust...you. Also check my Mods list and if you have similar mods any feed back would be appreciated. My main goal is simply to find out how much more HP and TQ can be expected from the Crawfords as they will cost about $600+ more than the DC Sports and it is pretty hard for me to justifyy that kind of a cost difference.

 

go to crawfords site. they have several dynoes of all their parts. as a small shop that is quite reputable i trust that the dynoes shown are relatively accurate of the results. your opinion may differ

 

off topic but how do ur car sound with the nismo exhaust and crawford HFC?? Easy it really loud and raspy or none whatsover!?

 

Like yourself, few members are doing dyno tests after each mod: its just cost prohibitive. Determine how much you are willing to spend for about 5 pounds of additional peak torque.
