Engine/Power - EJ20T (pre-2006 WRX and JDM) There is replacement for displacement, it is forced induction - OEM 2.0 liter turbo engines in the USDM WRX. 90-94 Legacy Turbo EJ22 turbo engines can also be discussed here.

I know a gutted uppipe is not the best but...?

I do not think anyone has tested that though.
Rallitek has two uppipes that are less expensive than Perrin. AVO is $10 less than lest expensive Perrin, GPMoto is $30 less.

I didn't know the Perrin was tapered? I know why it's good but I wasn't aware that any one was actually doing it. How much does the perrin taper and what other uppipes taper? also does any one know if the APS uppipe is out for us yet?

don't doubt the power to the stock gutted, here's a good example:

if you're not going for insane power, gutting your stocker would be a very cheap way to go.....buying a stocker then gutting is the way i went...cuz i wanted to take my time and gutted and completely cleaning the inside a few times, just to make sure there wasn't anything left
