If anyone has the link please point me there, I could have sworn there was a master HFC/header/exhaust size(inlet outlet) thread.

I am need of buying some HFC's and I need to purchase the ones that will make sense with my exhaust.


car is a de revup

Can anyone confirm with me that the megan header( not long tubes) are a 2.25 outlet?
If so then I would want to know which hfcs are 2.25 inlet and also 2.25 outlet since my borla has a 2.25 inlet.

I want to keep the flow right with no bottle necking.

anyhelp appreciated!

 

fyi 2.25 is another different then the stock exhaust(2.35).

 

i dont have stock im runing borla which is 2.25

turns out kenetix is 2.25 in and out
berk is 2.5 in and out

eneded up going w kinetix since it makes the most sense to keep the exhaust flow in line
