I'm looking to start modding my '02 WRX and want some feedback on catless up-pipes. I've read through the "first modifications" thread and many others and understand this is the most important first mod. What up-pipe do you all recommend without an EGT bung? I've heard good things about GrimmSpeed's unit, shown here:GrimmSpeed, but I want to know what others think.
Currently the only "mods" on the car are a drop in K&N filter and Excedy stage 1 clutch and ACT Streetlite flywheel .
Thanks for the assistance!
