The factory pipe bend are restrictive. BUT. There are a few modes you need to do to take advantage of before you will see any gains out of the DPs.
1, Get a tune from AJP or GH and add a 3 bar map to the top of the intake. you will need to tell the tune about the 3 bar. And best to do colder plugs too. GH has a power pack with all of this and a colder T stat but you don't need the stat to make it work, it is a small benefit. I do like it in the summer as it turns on the fans earlier and I think it help the AC do better in the heat.
2, Drop in k and N filter or EPP intake.
3 Good 93 fuel. This can be done with non E 91 and 2 gallons of E85 if you don't have 93 on tap.
4, Then down pipes.
5 HpFp.
6 Bigger turbos along with IC.
This is the building blocks of this set up IMO.

You suggest downpipes before the hpfp? It looks like they start at 3" and neck down to 2.5". Would 3" piping make more power?
