Please advice on options for Eisenmann race >
My car is a 2009 e90 325i LCI (European model).
I live in Vietnam, there's no Smog check here, so I can run cat-less (excuse me for the lack of the right word).
I was adviced to get Eisenmann race & center pipes first. Then later on, add a SuperSprint header.
My question is, since there's no Smog/CO2 restriction in Vietnam, What is my option for the most aggressive setup?
I do want the Eisenmann race as the catback. But I dont know which center pipes / cat / headers to use.
Any input please,
