get a bigger/aftermarket one. just like the OEM downpipe, the stock 02 housing is a bit restrictive and made out of very heavy steel to help with not only durability but sound deadening.
regardless of what was said above, ive never broken an 02 housing in all my years of building these stupid cars (heading into year 14 as of March). the easier and bigger the exhaust flow is from the exit side of the turbo, the more power youll make. you want the least amount of back pressure possible from the 02 housing back.
