BBR Catted Manifold First MOT (does the cat need to be hot)

Technical Area Engine, Transmission, Exhaust etc

Hi guys

I have searched, but as my question is quite specific I can’t find the answer I am looking. hoping for!

I have my first MOT with my BBR Super 200 booked on Wednesday.
When I was with BBR, the manager suggested the cat needs to be warm before going for the MOT to get it though the emissions testing… I was a bit puzzled by this at the time, but it then slipped my mind as I was too busy hooning :stuck_out_tongue_winking_eye:

A couple of questions spring to mind:

  1. Has anyone ever had a catted BBR Manifold fail for emissions?
  2. Has anyone ever left their car with the garage for a few hours before the MOT test time, which would allow the cat to cool down?

I plan to take the car in warm, but I have to drop it off around an hour before the MOT is booked for.

I think I am just being neurotic, but if anyone has any perspective on this that will calm my nerves that would be great.

Thaaanks!

Antony

Do you still have the cat in the mid pipe? If not then yes it will need to be hot.

Hi, yes original cat in the mid-pipe is still there. :slight_smile:

In which case ÿou will be fine!

I’m also interested to see how people get on with this. Normally I’d take the car in after a good run, but I’m thinking of leaving it with them for a few days to do an under seal and service beforehand. I guess I could just ask the garage to give it a thorough road test before the MOT to check that everything works nicely after the service?

I had my MOT done last month at Halfords. It took him three attempts to pass the emissions - he did have to get the car hot. (BBR220 with catted header)

Is the car fitted with the full exhaust system with the sports cat?

I have never been under the car but it has BBR tailpipes & the catted header!

How did you get the tester to check three times?

10

I didn’t, it’s what he told me when I collected the car. I thanked him for his perseverance. I guess a lot of testers would have failed it.

Ok, well I have just dropped it off.
I got it nice and hot anyway, and now it has to sit for a few hours before they test it.

Let’s see what happens…

Glad to hear it! Also useful to know that it is possible without the need of a friendly mechanic.

I’m not saying where, but I once saw a mot tester put the probe on a different car, because the one he was testing wouldn’t pass.
:shushing_face:

im not saying who, but some of us may have slipped £50 to have this happen on their heavily modified car :slight_smile:

however i think someone at the pub told me MOT testing stations are now expecting to have CCTV recording in the MOT testing bay. not sure if that was true or gossip.

@Antony_NC2 pleased it passed :slight_smile: mine is about to get fitted so ill be with you in 8/9 months lol

Hi,
In order to test probe the emission level of any vehicle it MUST be run up to it’s operating temperature. Ergo, a BBR Mid manifold Cat will be hot and assuming that it has not been damaged, or is worn out, will NOT be a problem. My BBR Super 200 MX has enjoyed 3 MOT’s with no issues whatever.
Best,
