Stainless exhaust header

[Daniel Neuman <dneuman@stars.sfsu.edu>]

 Hello All,
        Has anyone on the list installed the stainless exhaust header that
Stan sells?  I know that it hasd wider diameter than stock tubes.  Did it
help in performance at all??  DId the reduced backpressure push the 
power peak even higher up the rpm range?  
        Speaking of backpressure..were are cars not designed to run with a 
certain amount of backpressure? Will putting on a super free flowing exhaust
actually hurt the cars around town drivability??
