Clogged catalytic converter?
Today I removed my downpipe because I´m experiencing a lack of acceleration, overboost problems and strange behavior in my car (see here
), it has a Thermal R&D 3 inch exhaust with cat and 3 inch o2 housing.
I just noticed the stainless steel around the catalytic converter turned to color blue and reddish. To me it looks like this area is overheating but I want your opinions.
Shoud I gut this downpipe? I still need to pass the visual inspection.
