Hmm, okay. I am getting an RRM header next week and just wanted to double check that this is actually going to give me some gains.

 

Everyone seems satisfied on the butt dyno, but I've yet to see an actual dyno plot with a before and after...or even just an after.

 

That would be nice.

 

If a header is one of your first three mods, it can be safe to assume that dyno can be expensive. Of course, there is a fear factor, not meeting someone's expectation. That's human nature.

 

Yes, it's expensive. I doubt I'd take any pulls without major mods (hell I still haven't looked at my HP outputs), but you'd think in nearly 2 years of the RRM header being out someone would have dyno'd it.

 

Headers are definitly worth it but you need to upgrade the throttle body and intake mani to really feel the difference. I think what the kid meant to say is, did you gasket match the head to the headers. Other than that I'm not sure what he meant.
