I believe the SWB has only a Flowmaster cat-back system, and still employs stock cats and stock down tubes. As far as I can remember, the only thing "not stock" was the intercooler and the components used to make the whipple work (inlet, top, fuel rail). Otherwise, it doesn't get much more stock than that, in my opinion

Oh, and this car is VERY stock. It still has stock cats on it. With the stock M90 car only makes about 190rwhp.
I've talked with Don Pitman and have seen his car in person. That car made 310rwhp and besides the full MP treatment the car also had mildly ported heads, fuel system, long tube headers, full exhaust treatment, and dyno tuning. I think those are the only things standing between us and 350rwhp.DamonSlowpokeBaumann said:Being that there is supposedly a stock longblock SC running all magnum powers gear with 300rwhp I see no reason why the whipple powered setup cant top that. Seems that the 20+ psi was a problem..Dave ya gunna try a larger to reduce boost perhaps to 17 or so?
