Helix up/downpipe?
Opinions? I would assume it would work on the STi? Thinking about going with the HKS Carbon-Ti and Helix up-downpipe. Just curious what others think...

why would you need an uppipe on your STI?

Perrin DP = the bomb.

Why? What was wrong with the Helix? Was it the Helix Flex-type? Why change to a rigid pipe? I am going to get an uppipe soon so your comments will be most helpful.

You don't need a up-pipe on the STi. The STi has no pre-cat.

The Helix is a good looking downpipe but we had difficulty making it fit. The current batch is supposed to fit better but I've heard that before. I can't say anything about the uppipe.

Ah ok, much appreciated. Heard you guys say Perrin is good in the past. So the WRX dp will fit the STis?

AFAIK, the dp's are interchangeable.

This guy ran a 13.1 w/ just the Invidia/Helix dp.
