Description
The CORSA Performance Variable Sound Exhaust System (part number 21100BLK; Summit Racing part number CSE-21100BLK; UPC 847466022050) is a 304 stainless steel cat-back kit with a dual-in/four-out layout and split-rear exits.

It has 3.00-inch intermediate pipes and 3.00-inch tailpipes, plus four round, slant-cut black tips. Each tip has a 4.50-inch outlet, rolled double-wall edge, and 304 stainless steel construction. The system and mufflers have a natural finish.
