Looking for a good Up-pipe for my 03 wrx

Thinking about either Helix or Perrin.

What are your thoughts?

also if you like any other one please suggest it.

Helix is popular

If you have the time and tools, do this --

i got the helix. my biggest concern was fitment/leaks and figured the flex would help fitment. pita to install so i'd hate to readjust if there was a problem. which there wasn't!

 

Thank You Turfshark. That is the same thing I was thinking. Fitment/leaks

 

Go Perrin. Can't beat it. Perrin makes fantastic parts with great craftsmanship.
Install is a PITA but after its all back together and you go for a drive it will put a smile on your face...trust me.

It pulls harder than a stock wrx...and yes you can notice it.

 

I got the APS up-pipe and no leaks. I think there was a batch that the cast mold was bad as the thread shows on that webpage. That thread is three years old too. You can't go wrong with Helix, but I don't know much about Perrin. The best design for heat retention would be Inconel, then cast iron, and finaly stainless steel. If you get a SS up-pipe I would suggest you get it ceramic coated. I got my up-pipe coated ,even though it is cast iron, just for more performance and it is cheap.
