Last year I spent a couple of hours swapping the decat downpipe for the standard cat pipe, the weekend prior to my M.O.T

This year I have swapped the decat Centre Section for the standard Cat pipe, in about 15mins...much better.

'BUT' Is it still gonna pass ?

What's the success rate of MOT's using the CS instead of the DP Cat ?

 

my MY00 with H/S downpipe passed easily this year with just the cat centre section there was very little difference in the readings.

Did you have to give it a blast before the MOT to get it hot ? or did you just leave it at the MOT station.

 

You need to find a friendlier MOT station

 

Gave it a 20 min drive on way to mot ( subaru main dealer) it was sitting out side cooling down for about 20 mins (me starting to worry!) they drove it in did all the usuals and it passed. my only worring moment was when the mot tester said my Le Mans sticker was "technically" obstructing vision through front screen as it was in wiper path. He also said he gets a lot of cars in with just the center cat and most pass with no problem (as long as their running right).

Got it through with the center, see my other post for results
