Recently purchased a 2014 GMC 3500 crew, long box ,dually and the PO deleted the truck and i am wanting to go back to stock. all the egr coolers , down pipes are still in place so just looking for the DPF and CAT. i am wondering if a DPF and CAT from a 15-16 LML will work on the previous gen 11-14 LML body style? does anyone have any experience with this? i know for sure in late 15 the CAT has a 3 bolt flange that connect to the downpipe and the 11-14 has a band clamp. i have a guy willing to give me his DPF and CAT but like i said it's form a 2015 body style...His 15 is an early production model so i am lucky that it has the band clamp on the CAT that hooks up to the down pipe. my main concern is the programming and sensors if they will work with my 14?
any and all info would be appreciated.
