I fitted a japspeed exhaust system and japspeed Sports cats about 9 or so months ago. At the time I had some issues with the sports cats not being delivered/lost by japspeed. Eventually they came and were fitted.
Today i I had the car in for its MOT and it spectacularly failed on the emissions test. It ran 1.736 and then 1.572. Both times the car had been warmed up by the garage, who regularly deal with modified cars.
The guy guy at the garage doesn’t reckon they are sports cats fitted, has anyone else fitted Japspeed sports cats and had such an issue with the readings?
I’m gojng to take them off in the morning as the garage has suggested I check to make sure they aren’t just decats.
Thanks Shawn
