I just ordered a Cobb ap for my 04 wrx. Now I can't decide between the Cobb tbe or another tbe. I was looking around the web and can get an Invidia tbe + helix up for about the same price of a Cobb tbe. I want a system that puts out good pwer but is not too loud.
Can I put together diffrent brand up, dp+ cat-back that put out good power and fit together well e.g. Helix up, dp+Greddy cb.
any suggestions will help, thanks
