how are you?
i want to share my muffler change update
1st i remove front 2 round can resonator
-sound = not much different on sound little bit louder but better gas response and yes car got little bit more faster
Gas if 17 city all stock feels like 13~14 per gallan.
cost $ 30 to do it
i attach 3photos for 1st 2 front resonator remove
after 2 weeks later
2nd i remove center box resonator
so now i'm at 2front round can resonator remove and center box resonator remove
sound= much louder with kind of deep tone
power= since there is no back pressure loss power on low but high rpm very fast
gas= gas goes much faster like 10miles per gallan trust me on this you will see gas goes really really fast down.
cost =$ 30
note: after i remove center box resonator car shakes and little bit of buk buk buk sound
since there is no back pressure.
also when center black plate is back on.
