Just a little update... body shop is still waiting on parts, which is fine because so am I (corsa system is supposed to arrive on or around the 17th - hopefully sooner). I'm hoping someone who has done this bumper & exhaust conversion reads this and can give me a little insight on whether or not I'm heading in the right direction. From the numerous threads on several different forums I have put together a fairly solid parts list for not only the bumper job, but the exhaust as well. For the way I am going about it (getting my truck as close to a stock premium escalade as possible - on account of the corsa system i ordered) starting off, none of the exhaust will be "custom". Eventually, after the bumper is on and the corsa system installed, I will order the stock (rectangular) escalade premium tips and have pipes made to lay in those tips (coming from my corsa), but to just get it done and back out on the road it will be the corsa twin dual rear exit tips out of the escalade premium bumper. To make it so the corsa system is an easy bolt on job, I needed to get the proper exhaust hangers and install them. Thankfully, I found a caddy forum where someone had listed the part numbers for the required hangers and insulators to convert a stock esky to the premium... So, I ordered those, they came in today, and I installed them earlier tonight... seemed too easy... hopefully they are in the correct spots, and installed in the correct position... (currently I have no exhaust to "go by" or line up to make sure... and finding pictures of all the hangers in their positions for a premium esky, even a solid underbody photo has been... well... exhausting). I was surprised (and happy as hell) to see the premium esky exhaust hangers were BOLT ON!!! Made quick work of the install, now, hopefully, when my corsa comes in the mail, it will be an easy bolt on job, with all hangers ready to go... (obviously I will have to drive it to the body shop without the exit pipes bolted on (on account of the bumper) If parts keep coming, I'll keep installing! Posting some progress pics and parts list below for reference if anyone runs into any issues or needs a quick "look-up"....
