Okay, look at the s2000's Horsepower...
The only way true duals would work on a low 100 horsepower car would have to be smaller piping after the split ( y pipe ). Getting a dummy muffler just to fill the slot would look nice but noticable at times ( IE flooring it and when it's cold outside and you only see one pipe emmiting heat ).
I def would like to see the dyno numbers before and after the set-up.
