I think a 4in dp into a cutout and 3in exuast will work fine after reading some post on cutouts. One guy said he made 50rwhp just by takeing out his pre silencer. It also had a 1 point differnce on A/F ratios so beware. I really dont think I will have to use a cutout it just my choice.

Its not worth the extra ton of money for as little as 2-3 horsepower, if that. I guarentee you wont feel a differencen anyways. with 600 rwhp you got bigger things to worry about then more power. Traction is key.
