Let us know how it runs, and sounds.
Still not sure if 2.5" or 3" is the way to go.
3" dp people say no loss at all.
2.5" dp people say this is the way to go.
Who do we believe?
Which will benefit more in the end when flashpro comes out?

people said no loss at all on 3inch because is butt dyno,if you look at the dyno graphic you can see it missing low end. 3inch will only give you peak power. also another thing people with 3ich said they can chip tires in 2nd gear you can do it on stock dp.

I can chirp through all 3 first gears.... Did you end up getting your DP dynoed? Also another note is if you plan going forced induction 3 inch DP+ Catback would be the way to go. There are pro's and cons but I have the 3 inch DP + with catback and the car is much quicker then a stock si. I will get my car dynoed once flashpro comes out because I dont find it fair to compare these mods without a proper tune so I feel that a dyno now will be useless.
