okay i dint know where to post this thread so i gonna post it in here...
i have used the $200 ebay tri y header already and it makes pretty decent power on my 1.8 motor i dyno a while back...211whp and 137lbs. tq. and i want to know if it's worth it to puchase a Profab header for my new 2.0 build or just stick with the Ebay tri-y header??

 

yeah i believe its worth it. heres my 1.8 dyno with the pro fab header and my blown motor from cmi. yeah man i told you i thought it was a spung bearing but this **** happen instead i have no idea how this happen but oh well this motor lasted me 2 1/2 years of dd and abusing and driving it back in forth from so cal to sac

 

yea...? that dyno is useless.. anyways,

no your good man, for the money i would spend it elsewhere. I doubt your header is the weakest spot.

 

I want to see some dyno papers on Ebay tri y header VS profab header on 1.8 and 2.0 motors.....lets see em....

 

what was the cause of it. did the retainer or spring go bad or was it p2v contact
