I'm glad you brought that up, Travis. My use of the term "Stage I" turned out to be a misnomer: when I looked up the receipt, I saw that not only was I off by two years (it was installed in 2006 not 2004), but my exhaust is listed as "Performance Exhaust." Evidently, an exhaust upgrade was available as a stand-alone option at a cost of $1,500 at the time. I apologize for any confusion having arisen from my misunderstanding and faulty memory!
