The CORSA Xtreme cat-back exhaust is a 2.75in dual rear exit system built from 304 stainless steel and topped with twin 4.5in polished Pro-Series dual-wall slash-cut tips. It carries CORSA's Xtreme sound level, the brand's most aggressive tuning, delivering a deep growl at idle and a bold note under acceleration, while patented Reflective Sound Cancellation (RSC) technology keeps the cabin drone-free at cruise. The bolt-on system weighs about 9 lbs less than stock.
