If it's sluggish and rattling, maybe a collapsed catalytic converter? Too much back pressure, combined with the platinum catalyst vibrating. I'd tell the shop not to bother with the exhaust, send it back, and take it somewhere else.
Oh, and even the cheap aftermarket cat-back exhaust for these cars is $400. That's how I justified the MBRP to the accountant (aka wife). :)
