Hi all
I don't know those if anyone change b4 exhaust system for acr50?
Estima exhaust system consist of 3 stage. Catalytic convertor, resonator than muffler.
Since I read b4 an article that estima had a eccesive high back pressure due to catalytic convertor or which is also slight draw back the torgue n HP.
I am thinking to remove the catalytic and change the high performance resonator too.
I know the catalytic cat is for eco,
Anyone sifu out there can give advise and opinion.
Thk u in advance
