So I'm really looking to get a downpipe for my car. I'm currently stage 1 APR with intake. If I get the downpipe I probably won't go stage 2 until I get the rest of the intake. But my question is, will I have problems passing smog even tho I'm stage 1 with the downpipe. Also will I get any CELs. Oh and the downpipe I'm looking at is the CTS Turbo one. It's on sale right now on Urotuning.
