The stock piping on a 6.2 truck vs a 5.3 truck is different considering stock 6.2 is 3.5" piping and the 5.3 is only 2.75". Anyone care to confirm/deny?

More than likely that is why the Gibson 6.2 exhaust will not mate up to the 5.3 without modification.

Why would a 3" system fit a truck that cones factory 3.5"... order it if its 3" cause your 2bolt flange will bolt up 3" if its on a 2 bolt socket ball fitting like most gm exhaust!
