Those of you with Helix o2 housing's. Just wondering, how is the 02 holding up to daily driving use? Any problems with cracking or exhaust leaks? How durable are these Helix o2 housings? Just wondering as I'm looking into Helix, ebay as well as ported stock o2 housings. I could get a good deal on a Helix 02 housing which is why I am wondering how good is it

Thanks

 

I have had mine on for about 2 years now, still looks good and I have had no probs at all

 

Bump for Helix O2 housing review! Don't mean to jack the thread or anything, but whats the outlet diameter for this housing?
