As I posted a couple of weeks ago, when deciding what mods to do on 2001 GTS, it was recommended to me that I give strong thought to headers, and fact that they MIGHT cause engine warrenty problems, ESPECIALLY if local dealer doing the work was NOT willing to "overlook" headers when reporting issues to Dodge. Borla cat-backs did NOT seem to carry the same level of worry. Remember, Dodge will likely be under much tighter scrutiny with management changes, and Chrysler's recent losses. Of course, above is speculation, but many feel that the "rules" are changing...fewer give-a-ways, fewer cases of Dodge Zone Rep "looking the other way". Remember, this was a TOPNOTCH, well known and HIGHLY RESPECTED dealer source giving me the above heads-up. At this point, one charts one's OWN course...Happy Vipering!
