Im about to purchase the hks carbon/ti exhaust and I need to also get an aftermarket downpipe, theres no way im buying one by hks they look too weak. I need to know which downpipe works best with this exhaust.

 

Perrin DP, Helix DP are both nice.

 

Helix Fo Sho

 

yeah..helix is good. anything with a belmouth/divorced wastegate will work fine

 

Titek downpipe (aka Old Helix Manufacturer)

 

+1 for perrin downpipe, have that on my 05 wrx

 

thanx everyone, looks like ill go with the helix

 

I have an invidia n its great

 

humm i hear some ppl have problems with the divorced bell mouth as far as the wastegate flapper sticking or hitting it so if u do go divorced i suggest a good measuring of these things and maybe even some custom machining work to the d/p idk though i have a open bell mouth im going EWG anyhow so i dont need that lol just slows spool in my case..
