A catalytic converter requires a certain operating temperature to perform properly. Excessive temperatures will reduce cat efficiency and possible reduce operating life. Has anyone with a wrapped downpipe experienced (and a minimal assortment of other mods) 1.) problems passing smog tests, and/or, 2.) accelerated degradation of the catalyst bed?
