I totally agree on the minimalist thing. 90% of the people have seen so few of MP5's around here they dont know what I've done to mine. And as far as breathing better, he talked about needing 2 banks of cylinders to justify duals? You will have a very hard time to find any stock v6's,v8's or even v10's that have true duals anyways. They all go headers to a "y" pipe then to one cat then they split again to the duals in the back. its about looking symetrical in my opinion. With the one big pipe on one side I thought it looked a lot like my kids Muscle Machine micro tuner things, with the way oversized turbo, rims, exhaust, etc.. Almost a caracture (however you spell it!) of a real car. Cartoon like. So I used 2 of the mazdaspeeds to balance it out. And since as of this weekend I do have the turbo in, I guess thats ok then.
