Just wondering if there was a difference between the 1998-2001 and 2002-2003 Durango's as far as exhaust? I just purchased a Gibson cat back, after reading that it fit the 98-2003 Durango with all engines, then read the literature that said it fit the 4.7 between 2002-2003. Just wondering if I fubared myself or what? My personal ride is a 2000 4.7 SLT 4X$ Durango. TIA, cruzerjd
