Are all the bolts needed to secure the downpipe to the turbo?

Weir doesn't have the flange. I was wondering if I could get away wit drilling the dp flange and holding it wit 4 bolts? I know I can get 4 to bolt up, but would the heat affect the sealing? Its just gonna be an open dump to get heat out of the engine bay.
The DP came from the same guy i got the manifold from. He was using a turbonetics t3/t4, and i'm using a t3 with a goofy *** flange.
I wanna use this DP so I don't have to have this ---- welded for me cuz i'm a :1 with no welder

you'll more than likely have exhaust leaks

exhaust leaks affect afr readings for tuning

depends on how much you care

soda can gasket with the copper spray. And I was figuring an o2 bung for the wideband less than 12" from the turbo.
I'm aware exhaust leaks will mess up A/F readings.

Is there a minimum length the dp has to be to not mess with a/f readings? or as long as its reading all the exhaust gas coming out of the turbine it will be fine?

I ran a flange complex and I torched out of a toyota bumper and cleaned up with a grinder. It sealed ok until I took it on and off a few times and started snapping bolts. I have a new flange I've been too lazy to put it on.

Like I said it depends on how much you care
