hey guys, first time posting. 02 wrx with light mods, rfl bov, cobb air intake, aftermarket boost gauge, muffler. I maintain the car very well, runs awesome. I purchased headers and an uppipe for her. If I keep the oem downpipe and rest of the exhaust on the car, is there any problems im steering into? or any advice? thanks

Welcome I the site. Have you ever driven your car with he stock bpv on it instead of the rfl?.( saying this because these cars arnt meant to have a vent to atmospheric bov on them there meant to recirc the air back into the intake) And what brand header did you get? The stock up pipe on your year has a cat in it. So replacing it with a non catted up-pipe is a great idea. There will be a check engine light after install I'm pretty sure since you will be deleted cat.
