Could this help pass MOT emmissions with decat?
Could this help pass MOT emmissions with decat?
I'm sure ormi and maybe others will know the answer to this one - Do the emissions tests on an MOT have to be conducted with a certain exhaust flow? Or is it literally shove something up the exhaust and take a reading?
I'm just wondering if I can pass with a complete decat by using one of these:

ive been looking at one of them, more to keep the noise down than emissions though
I know i have a straight through 3" pipe from the turbo to the back, with a very small back box
Yeah that's only going to reduce the noise, not change the emissions.
ormi is the expert, but from what I can tell, the emissions are tested at both "idle" and a vehicle-specific "fast idle". If you've got a decat then you're not going to pass those.
theirs two mesurements taken first one's taken with the car up to temp and reving between 2500-3000 rpm then the second one is taken at idle....
some cars will pass some wont......example mine and moleys have no pre cats he couldnt get his to pass the emmisions and mine sailed through....
another problem with this stupid valve you will have to remove approx 1.5 inches from your lovely expensive stainless exhaust...
A bottle of Red X and some high octane fuel and a good thrash of the car before the MOT will work wonders
