View Full Version : Up-pipe

03-21-2006, 04:01 PM
I am looking into the type of up-pipe I want to purchase for my WRX. To flex or not to flex? Braided sections create more turbulence, and could leak, but some solid pipes don't fit as well. Correct installation is key I guess...

I have heard good things about:

-helix flex up-pipe
-STi up-pipe( but has smaller diameter)

I have heard bad things about:


Basically I am just curious as to what everyone else is running and how they like em.

And I am not going to gut my cat in my stock up-pipe, already considered that, want a bit more flow.

Helix Perrin and Cobb are always the brands that I hear and read about. I would stick with them.

^ Only problem is Cobb is almost twice as much. :D

Helix and Invidia are the same if you didnt know already

The STi uppipe should give a perfect fitment, and I doubt you'll even notice the smaller diameter. They come up for sale used occasionally when the STi boys change their headers... going rate seems to be around $100 Cdn. (used)

I've got the Helix and have no complaints at all, great looking product and only cost me about $200 brand new. I think alot of the problems people have is a bad install. I got someone who knew what they were doing to help me and 10,000km later still have no problems.

I have an old skool BPM flex up pipe and have had no problems. It's all about installing it correctly.

Hey Mac, messaged you about JDM parts.

I just ordered the Helix one. I already have the Helix downpipe, and so far so good. I'm pretty sure the up pipe will be the same.

I probably will not install until it gets a little warmer out, but I will write a review.
