best upipes and headers for your VF35 are supplied by Harvey on here, drop him a mail, he will sort you out

Richard07

so why replace the std pipe?? i thought they had a cat in

Pramas

correct matched upipes can bring the spool up from turbo in so much quicker, a decent mod for that alone

Richard07

yeah i thought that but just got a bit confused with the above post, whats the japspeed ones like?

Pramas

well basically you get what you pay for, iam sure they are fine, but Harvey is the man when it comes to upipes, drop him a quick message, iam sure he will help you out whether you go for his or japspeeds

Richard07

yeah i did msg him a bit ago and got a price, there are some mixed reviews about japspeed parts but i must admit the quality of the system i got from them is spot on the welds are very well done and seems good tough quality

Pramas

i think and i stress here " i think " japspeeds arent lifetime guaranteed, i tend to like to know once its paid for thats it.
Having said that ive seen lots of people quite happy with there japspeeds so i wont speak bad of them at all.
All ill say is i know how much flow testing went into Harveys and in my opinion the cost is negligible. Quite a few of the bigger builds are using them so they must be pretty ok

Hi iv got a Japspeed full turbo back 3" it's been ok for 2years now. Harvey knows his stuff but if I was u I would keep the STD Sti up pipe with the vf35. Change the up pipe and headers if u want once u get a bigger turbo and trust me in 8 -12 months u will want more power u always do

336 hp and 342 lb tourqe. Just an exhaust change and good cosworth panel filter fuel pump pfr7b spark and a great mapper and clean v power was freshly put in to my car because that makes a difference to.
