Been filling in some pin holes in the welds in my manifold that i made.
Just wondering, if i miss a couple, will this effect the emissions much?
There is no lamda sensor to corrupt. And manifold will be heat wrapped if that makes any difference.
So would a tiny leak cause me to fail the emmissions test? or do i need to make sure i fill them all?
Im not too worried about the exhaust long term, as planning to get something custom made after IVA.
Cheers
What engine and what level of emmissions test will it have to pass?
Its a 2008 R1. Not sure what the emissons level are?

Exhaust assembly paste ( FireGum or similar) will seal it until it carbons up.
Thats what ive been using (the ceramic type that comes in a tube for a gun).
I also need to use some around the flange that goes into the head, as thats leaking slightly.
Just wondering for if i miss any leaks.

Persevere and weld them all up, nothing else is permanent.
Even a small exhaust leak on a car with cat and Lambda sensor can cause the Lambda reading to be too high for MOT purposes
Even if there is no lambda/02 sensor?
That may depend on what your emmision limits are ? If you have an age related plate you may have a lower limit than a Q plate
It wont effect the emmisions but surely the system has to be "gas tight" to save nasties getting into the car......?
