I'm with 01ssreda4. EDGE is a good brand in my oppinion. I went with them, and am very satisfied. I'm not saying it's the best simply because I have never driven a car with a Yank or Vig. But if your car is going to have nothing more than bolt ons it will more than handle your needs. It also has a 1 year warenty. So if you don't like it send it back and go with a Vig or Yank. Also don't forget to get a trans cooler and shift kit installed when you get one
