what engine do you have?
I was looking at the magnaflow site the other day and for the v6 01-04,
they claim through
their dyno results an additional 10 hp and something like 23 ft lbs of torque. Check their website out to make sure I didn't mis-qoute it.
As far as dual exhaust goes, I don't know anything more than what I have read about aftermarket mufflers in the past.
Under faq, they claim that the average range of power increaes was somthing like 10%.
Thats all magnaflow.
Check out the different exhaust companies websites (magnaflow, flowmaster, banks, gibson, spin tech ...) to see what they say. Whether or not they distort their figures, at least you might be able to gain some kind of prespective.
