V-Stacks make a noticeable difference :fact
I believe additional gains can be achieved with a high flow air filter and especially tuning.
#Hi Guys!!Been looking thru old threads..... DOES ANYONE know where I can purchase V-Stax for 07R1?!! Factory Pro and Graves only have available for up to 06R1..........
Someone even said they'd remove it....... that's why this forum's here i guess, for advice and inputs...... let's hear other other opinions.........#
Could be that the variable length inlet tracts negate the need for/benefits of Velocity Stacks?
EDIT - +1 on previous post - You beat me to it.
M 4C8-A4460-80 ?477,37Dude!! ..the 07 and up already have variable length v-stacks(their lenght is computer controlled) ...you don need to buy anything.
