My flexpipe cracked leaking untreated exhaust fumes. removed dpf to gain more room. downpipe disconnected and free but cannot remove up nor below. Watched video(s) but they dont provide enough detail on exactly what parts must be removed. The body of the cat seems to get wedged between the firewall and some emission equipment that looks to be very difficult to remove. others have indicated they did not remove this body. not able to drop below either.
any detailed experience /suggestions helpful. 2011 q7 tdi
