I have a Apexi GT exhaust, and I need to get a downpipe, what issues will I have, or should I just bolt up the dowpipe and be fine?

Thanks so much!

Most people say that DP + exhaust is ok until you open up the intake but then that A'PEXi GT exhaust flows pretty good so I'm not sure but I would think it's ok

You should be fine with those mods. Those mods are extremely good for the FD. Make sure to keep an eye on the boost gauge; make sure it doesn't spike. Also, an intake will work great with those mods. After these mods you should look into upgrading your ECU.

Like they said you should be fine...only problem you'll have is installation of the DP if you choose the wrong one. M2 and HKS allow to install W/O removing the turbo manifold studs (THANK GOD, they can break during removal, and is just plain annoying when doing the install). I have the HKS, and no problems, but it's not SS like the M2.
Get the ECU upgrade before the mod you do that will alter air/fuel mixtures in your engine.

you should be fine...i ran the apex gt and midpipe together with no other mods.

i ran an intake and a cat-back and my af gauge still read pretty rich. i wouldnt worry about it too much but not all FD's are the same
