who cares what the exhaust its just piping,
and who cares about beating a 3800?,
and the funny part is that ppl keep comparing the 3100 to the 3800, there to completly different platforms, the only thing they share is the car, so theres is no need to compare the too
oh and blue, i could give a **** less about your highway mileage, at crusing speeds babing it on the highway yeah i bet you do get good mpgs
