Difference between DUAL and SINGLE
 

If i only get the Greddy EVO DUAL exhaust,(w/o single exhaust)

is this mean that i get TWO mufflers wihtout long pipe

OR is this mean that i get 1 muffler with the long pipe



How about Apexi?

if i only get the dual exhaust ,,

is this mean that i get TWO mufflers without long pipe

OR is this mean that i get 1 muffler with the long pipe

Eh, I really don't understand you, but the dual option creates a Y with two pipes coming out to mufflers, like stock.

yeah, I have dual exhaust on my car.........it's just a Y pipe then it has two mufflers on the end
