I see this mentioned around from time to time anyone on here with a wrx done this?
Is it the butterfly valves inside the manafold of the wrx that aren't there in the sti red manafold ?
Red somewhere the tgv helps with cold start emissions is there any advantage for me to do this?
With my set up
Vf35
3inch pipe work
Sti pinks
Sti top mount
Sti uppipe
& sports cat
Cheers for any info lads
