What size backbox would be best for an EG3 (Civic 1.3 dx)? I read somewhere that a car with little power like mine shouldn't have one bigger than 2" as it will lose power instead of gain power, is this true? Thanks.

if your gonna replace it all, might as well put 2.25" on it. it'll sound a little better and i doubt you'll notice any power loss. those 1.3's push like 60hp anyway..

- Wed Jun 09, 2010 9:47 pm #199551 well, if your worried about back pressure i'd assume your motor is NA, and since you stated you have the DX with the 1.3....




bolt ons to that motor aren't gonna get you much.. so ya, maybe 60whp
