This is a 2007 Cadillac CTS 3.6L with a custom Exhaust. From the stock cats back, 2.25" SS pipes, Magnaflow Tru-X Pipe (part # 10790), Magnaflow dual in/out muffler (4x9x11, part # 11378), then out to my stock "Sport Appearance Package" tips. Also a K&N FIPK is installed.
Per request, here is a crude diagram of how the setup looks: http://i254.photobucket.com/albums/hh120/SvB4EvA/Exhaust.png?t=1295975070

2008 Cadillac CTS AWD 3.6DI 0-100 mph
2008 Cadillac CTS4 3.6DI. Has about 2500 miles on it. Will probably do better when it is more broken in. Had the traction control off, like that helped at all. Had it in Sport Mode, the A/C was on, and a full tank of 87 octane. Overall, I really like the sounds it makes.
Cadillac Cts Exhaust work
This is my 2004 3.6L Cadillac Cts with some work done to it. I wanted to show the corsa with an xpipe because my next move is adding a magnaflow dual in out muffler in addition to the x pipe
