i've been doing a little math here. some have suggested that the ideal size exhaust for the Holden V6 buick engine is 2.75" now this is a very difficult size to find (i've never seen one that size, have you) so most opt for the 2.5" which is a little undesize but performs better then a 3" on a fairly stock engine with a few mods. now, doing the math a twin 2" system should produce approximatly the equevalent flow to a single 2.8" system which is much closer then the single 2.5" system. has anybody out there experimented with this type of setup on a V6. any ideas on this comments etc please
