Just got the Corsa exhaust installed on my 2005 STS4. Just wanted to let everyone know the sound is outstanding, quiet cruising at highway speeds, but a nice growl during acceleration, starting and idle. The 4" tips fit perfectly in the factory cutouts and look outstanding. I went to the Corsa plant and while the exhaust was being installed, Jim Browning Jr. gave me an outstanding tour of the facility. The build quality of all their systems, whether automotive or marine, is outstanding. They use lasers for cutting and hydroforming to manufacture parts.
If any of you are thinking of getting the Corsa exhaust for your 2005/2006 V8 STS, I highly recommend it. The picture on their website: www.corsaperformance.com -look under whats new--is of the owners own car.
