mopar headers, catless mids with a magnaflow catback
the only thing i can think of with out seeing it is to slide your exhaust all the way back on the hangers should allow the QC extensions to have a little play and maybe come out so that you can get the back on perfectly then slide everything forward. Thats what i had to do with mine....Just make sure you get some WD40 or little bushing grease on the exhaust hanger studs so you can move it around easy. Once you get the troubled section on you can get everything back tight....
