I've waited a long time for this. So I just bought some "Stage 2" cams for my 2.5 mazda 3 without really thinking about the repercussions (even though I knew there would be). Am I going to need larger injectors and/or a bigger fuel pump? I'm running E85 now, and as we all know E85 eats a lot...

hey guys, correct me if there is already a post on this but I'm just checking to make sure that a 2013 MS3 exhaust will fit a 2010 2.5 hatch without any problems. I know that the 2010-2012 match up well but I just wanted to be sure that it would still work since the models are 3 years apart...

I can't remember if I formally introduced myself to the forums, but I thought I would definitely do that now. I purchased my 2010 2.5 s hatch in at the beginning of June '13 and I love it so far. I was driving a CRZ at the time, which I owned for about 6 months prior to trading in for my 3...
