Alex has the cat-back from invidia and it sounds pretty mean, i belive the same company that makes it sells products to Helix and I have yet to hear anything bacd about them.
i agree with wrx-wrc... when i was looking around for a downpipe, i had a lot of options... from what i read, helix and invidia were basically the same thing... however helix was cheaper and people said that invidia had better build quality... regardless i bought the helix catted downpipe and have been extremely happy with it... helix's turboback is one of the cheapest ones on the market... i believe gotsol has it
I'm running a catless setup (godspeed dp + invidia n1 catback) and my car sounds angry (even more so on the track). Invidia quality is superb, fit and finish is excellent. I like the invidia because of how straight through it is (notice the picture). My intiial dislike was the angled can, but it grows on ya eventually. There's a slight rattle, but I think that's from my gummy hangers. Feel free to ask any questions.
Thankz guyz, I met a guy that said he can get invidia stuff @ cost + shipping just just wanted to about the quality aspect of it.

I might end up getting an invidia or helix when I start modding. Do you think that it would be cool on a wagon?. Mark
