I'm putting some hybrid turbo, nothing special, little more power towards standard turbo. I already have 3" exhaust. I was wondering shall I change the downpipe, put larger downpipe or stick to stock one? I don't want to loose anything on spool with larger downpipe. If you are suggesting larger downpipe what size should I put? 2.5", 2.75" or 3". Thanks

3" downpipe would improve spool up

Let's put it like this, could I experience any losses with my setup with 3" downpipe? I have Gtec1 + Hybrid Turbo
