No, not at this time. I'm researching catbacks, looking at Stainless & aFe. A note on the MPG's. Before installing the Stage 1 I was really lucky if I ever got anywhere close to 15, city or highway. I installed the aFe the middle of last week and all I've been doing is "testing" it out. I'm now getting 16+ city and 17.5+ highway, combined 2 / 4 lane highway. I could tell I hadn't reached the max on the highway MPG's yet.
