I have a 96 K1500 5.7 Suburban and am wondering if anyone has tried either the 17260 side exit or 17186 rear exit Flowmaster catback system that is listed as fitting a 96 Silverado standard cab longbed. There is nothing for the Suburban except single side exit, no dual exit. Both vehicles have a 131.5" WB. Am I missing something, or should that work? Hope some of you have treid or know if someone has tried this.
