I looked and looked, but couldnt find the answer.
In a couple places, when people talk about mods to do without voiding their warrantys, some people say gutted UP/DP, or STI UP/DP. My Q is this, isnt the sti a 2.5L? Wouldnt that make the STi UP/DP different sizes? Thanks all I got!
Thanks a ton!
If there is another thread about this and you can find it your name must be google!
