Yes, i searched.

Now, im new to the evo and haven't gotten under mine yet(got it 2 days ago), but im getting a downpipe, testpipe, and catback today....now, does the downpipe not bolt to the turbo on these cars? is there a serparate o2 housing? if the downpipe doesn't bolt directly to the turbo, is the o2 housing a bottleneck on the exhaust system? any help and explaination would be greatly appreciated.

the O2 housing is not really a bottleneck in the evo, but an aftermarket unit will yield an additional 5-8 WHP i think.

 

Which means it is a bottleneck. The more air you flow, the more of a bottleneck it becomes.

 

ok, cool. can anyone point me in the direction of an aftermarket o2 housing? i didn't see any on the couple of sponsor sites that i browsed. maybe im blind, LOL

i did see that vinshu had one, but didn't see it sold separately....

 

PM speednstylez.

I just recieved the Megan housing from him for 115 shipped. You can get it for less on Ebay (100) but I have dealt with this guy before and I like him. The quality of the piece is amazing. High quality welds and construction. You can't go wrong, especially at that price.
