    tried a search but not found whats best to do.
    i have purchased a jetex backbox and getting it put on this evening.
    im wondering for a bit of extra grunt about getting one of the other 2 silencers lopped off.
    whats the best one to remove sound wise are they the same and am i thinking it is as simple as replacing with two straight pipes or should they cross?
    cheers

    My own experience from just removing mid silencers is that you get a lot of low tone noise in the car at highway speed. So best is to work on only the rear silencer or replace the mid ones with something of a more free flow type, but not delete completely.

    spot on mate, il get some nicer silencers welded in instead then
    do you know if the silencers cross the exhaust flow or keep the flow seperate?
