Dundon GT4/Spyder Race Header Group Buy

Got it...but I was referring to people with other brands that in order to compare you need to have done all dyno tests using the same procedure. In my case I have dyno tests but were not done using DMS procedures so if I go back to test the car using these new procedures probably will get different results....hopefully better and more representative of what happens on the street or track.

Yes cargraphics + tune made less power than DMS headers alone. I dont have access to the dyno graph yet.

I am skeptical that a proven design (cargraphic) header + tune, would make less power than just another set of headers.
Put the kool-aid down and lets get some real talk going here... this can only help the community, so it baffles me as to why the GT4 owners are so reluctant to seek the truth... Fanboi attitude won't help the platform grow.
-Food for thought.

I'm sorry.. But you were so verbose on "Putting it to bed".. Now you make outlandish claims without backing it up with actual data... and I'm in fantasy land?

I don't have the graph it was posted on the GT4 International whatsapp group, someone must have it.
edit: wanted to add that the dynos were not done same day too.

How are two different cars with two different headers dyno'd on two different days comparable?

So, since there is little or no performance advantage to catalyst delete—in the test above, anyway—can you speak any durability advantage of no cats at most tracks? Is it different than, say, Daytona, Sebring, or Road Atlanta with those long straights?
Having been pegged as a "global warmist/tree hugger" (I am neither), I am curious, as I haven't heard of factory catalysts failing in track use...and certainly not in big numbers.

Sorry...I couldn't resist. Kareem: Thanks for posting your findings, and your car is plain gorgeous. Makes me rethink my choice of Guards Red.
