I purchased the Corsa Performance Exhaust system offered by Corsa Performance. Jim Browning Jr, who I knew in the Marine industry says , you have to try this system on yor STS. Whats nice about this system, General Motors Cadillac Division Worked with Corsa Performance on developing a system that would be indorsed by Cadillac.When the two boxes arrived U P S at my front door,I called my local Cadillac dealer and had it installed.After the installation, the system sounds AWESOME!!
The STS sounds like a four door Corvette. The tail pipes looks hot and the response is exactly what this Northstar needed. Breathing room.Whats so nice its General Motors Approved! and does not affect the warranty because of their joint venture.Is it worth doing? Absolutly,hands down! No chip change. just bolt on and make a statement.You can see and hear the system on Corsa"s web site at www.corsaperformance.com
