The issue is that the outlet of the Works O2 housing is a full 3 inches.

Besides the Works downpipe, what other downpipe works with the Works O2 housing?
What downpipe is a full 3 inches on the donut gasket side?

I think the Invidia O2 housing is 3 inches on the outlet as well, so what downpipes are you guys using?

 

no one?

 

Just get the Works downpipe. I'm running it with a 2.5 o2 housing because the Works downpipe includes an adapter to run either 2.5 or 3". It clears the ACD and oilpan just fine too.

 

Why don't you want the WORKS Downpipe? It's proven to fit and work with that o2 housing, so why not?

 

i'm looking for cheaper alternatives, thats all.

 

Maybe if you didn't buy that overpriced 02 housing you wouldn't have to worry about that lol.

Just teasing you. I had the Helix and it was also a 3". Invidia will work as well.

 

I also had a helix at one point and if i remember correctly it will work for you

 

Works use to have a 10% discount around the holidays. Not sure about this year though considering the economy.

I say, don't be cheap and save up some more money. Get the Works with the ceramic coating. I had it and it fit perfectly, clears everything, and I agree with Works that the ceramic coating is essential for improved reliability.
