headers and upipe
as im rebuilding forged and got full 3" decat system 2 fit, im thinking of doing somthing to headers and uppipe.
whats the gains, and whats best 2 do to them. change or port. also what a decent up pipe, iv heard storys of sum that done fit well. also, last one :) is it beter 2 increase headers and up pipe bore size? |
harvey port's them , apparentley alot of the tubular stuff can affect the spool of the turbo etc etc unless your going over say 400 i think alot of people recomend you just port etc etc and the bigger the pipe isnt allways better .
|
what about up pipes, keep standard or change
|
I went for Harvey's up pipe and headers on my old wrx, made a good difference. Will be doing the same on my type r.
