I just go the helix up and down pipe combo yesterday, very nice quality...i wasnt expecting a lot for $439, but damn these are beatiful. Not to mention it's jdm.

I'm installing the dp today, I'll post back with the results.

I don't think Helix is JDM. They were made by some oversea company.

I just got my Helix up and down on yesterday. I like the pipes a lot and the quality seems very high. Also, the uppipe has a flex section.

The main think wrong with it that people complain about that it is designed just like the original subaru factory part. Most other downpipes have a bell mouthed or divorced type pipe that lets the wastegate gases let out with ease. I personally like my HKS pipe too, I don't have that much money and this was a good investment, that's what my "butt-dyno" says
