Every summer I have some sort of overheating problem with the car only this time the CAT is making loud thumping sound when I rev the engine.. this was after being stuck in traffic and after a while the car felt completely sluggish with coolant temp going 90 to 100 back and forth. Nice to drive at first but when it heats up in traffic or when the weather is hot everything feels heavy and sluggish and revs being erratic at times. Every time I start the engine when it's hot the revs drops at first (as if it's going to stall!) before going to idle.

After having a look at the CAT I haven't noticed any blowing and there is no errors displaying, but something is going on inside the CAT like the baffles are damaged? And I can't be sure if it's coming from the CAT as there is no errors showing maybe it could be the middle section? Although I only recently got the full scorpion exhaust last year. Do you think the CAT is causing the overheating issue or the overheating of the engine caused damaged to the CAT? Any thoughts appreciated.

Thanks

Well the if your CAT got a problem when the car get warmer,that means the airflow get slower,which make the performance poor,as warm air is not getting out from the exhaust as it should,which cause the engine to run bad in it's champers,this is how I think about it,I would consider a DeCat if I were you,and then car will runs much better.

What's a decat, as in no cat? Won't that wave anti-pollution faults and fail MOT? So I should be looking at one of these then? www.ebay.co.uk/itm/BRA...2c82d08ac3 Thanks.

decat=No Cat as you said,it won't wave the anti-pollution fault as you will use 90 degree elbow to fit the low stream oxygen sensor,but according to the new MOT law,any car with a decat will failt MOT,so all you can do is to fit the CAT when you have mot,and decat it the rest of the year Smile

And yes,that is what you need to fit,your car will drive much better with this on,trust me ,you can remap it too Wink

Car is already mapped. This pipe will replace the scorpion middle section then and directly fit onto the scorpion backbox right?
