I just purchased a 2008 CTS AWD 3.6DI and want some suggestions for some modifications that will give a little bit of performance.
Replacement HID bulbs
Borla Mufflers (having custom cat-back installed)
Any ideas on what to do next? Cold Air Intake? ECU Tuner?
I am coming from a 2005 WRX STI Stage 2 Turbo so I am adjusting to the speed loss and obviously want to add some inexpensive performance mods.
Thanks in advance!
