I want to know how do the an-r compact header performs on a gsr engine lets say w/skunk 2 stg 1 cams stock bottom end intake manifold compared to a jdm itr header? if you have dynos with the an-r please post i want to get a idea how the header performs. I search and nothing came up for an-r. And i don't remember them being in the header challenge, so input would be helpful, thanx

 

urgonnalearn2,
there is a dyno floating around out there of almost the same comparison you are asking about.
the an-r header with street collector made about 7whp more than a ported jdm on a stock b16 i believe it was.
someone out there has this dyno chart.

 

this was untuned and with only intake and exhaust.

 

ANR ownz j00! i have had 2 an i love them, make good numbers

 

Ok the dyno would be great if i could find it, I tried searching still nothing if you know where it is post the thread of the dyno. im still searching

 

i made power with the Randys headers ( so called AN-r) over the jdm itr...mine was the equal lenght ones though...

 

i have the AN-R Compact header and its way better than the JDM DC 4-1 with 2.5 collector. Mid top end comes alot quicker. took me from 13.8 down to 13.6(ran open header. and ever since i got the AN-R ive been shoot flames at everyone

 

sounds good!! anyone know where that b16 dyno is with the an r vs jdm itr????
