Swapping Cats back in

[GT Driver]

Quick question: what is a reasonable labour time for a garage mechanic to swap out decats and re-fit the OEM Catalytic converters?

 

Bolts in place are very new - only fitted for the past 3 months.

 

Thanks in advance.

1 hours labour if no issues.

If you have all the old nuts for the cats, then no more than 2 hours.

I just did this on Saturday on my back in the driveway, so should be a good bit quicker with a lift.

I had my decats in for 2 months, and put the cats back in for MOT.

 

Edit : I had a tea break half way through

So 1 hour then

Thanks for that. The old bolts and nuts on the Cats were too rusted to be re-used to I will use the berk bolts to refit them back in.

You'll need to make sure they're the right size. The holes in the cats are a small diameter.

You'll be getting a call when mine fails on emissions

No friendly Mot testers in your area then

Thanks for the heads up. I'm bringing it to an exhaust specialist so if the bolts don't fit hopefully they will have some that will.

MOT's are run by the DVLA over here and performed by basically jobs worth civil servants

Got this sorted on Saturday morning so stock cats are back in!

 

The decats were a little disappointing I thought - I had done a lot of reading about them but didn't realise they were as raspy as there were in real life! Also I had noticed a little torque loss when fitted - but in fairness I had no mapping done. This was confirmed when I took the car for a blast after the oem cats were refitted. Now pulls like a train.

 

Did the pedal dance too and cleared the EML.

It's funny, I thought I noticed more torque with the cats in after I went from decats -> cats, but you don't really notice a loss the other way around, so I'm happy enough. I enjoy the noise too much as it is though, although I'm not sure I could make it a daily with the decats in!

I'll second this, I definitely noticed a loss in torque when I put the decats in. Also doesn't feel like it's pulls as well top end. I haven't got round to mapping mine yet either so I'm sure that would sort any issues anyway.

Yeah the car just felt sluggish approaching 3k rpm - and with the oem cats back in it now has a strong pull from 2k onwards. I know with the berks they 'hiss' around the 2-3 rpm mark when coming off throttle - say approaching a traffic light. You can actually feel a bit of 'drag' during this time - the car is pulling back or something - definitely a restriction in the system.
