I'm in the same boat as MexGT. I want a set, but I'm not sure which are really good for a daily driver. I get mixed reviews on the power gains. Mark estimated that he got 35-40hp, but wasn't sure since he had another mod done at the same time. That's still a lot of power from one mod. And in the grand scheme of things, it may be cheaper than a set of headers with almost twice the power output.
Aside from the power, I'm also concerned about the sound. I like that idle, but I don't want the car shaking all to hell while I'm at a red light.
I think Stage 3 is out of the question, but what do you guys think? Mark's car is a bit of an anomaly due to the number of mods he has. Stage I, II. or III for my daily driver?
