Unfortunately my GLS450 is at the body shop with very minor damage to the rear diffuser. Shop owner is an enthusiast and told me the GLS63 diffuser and exhaust tips are similar price and I can use them instead. Apparently the GLS450 with AMG Line and GLS63 use the same bumper with only the diffuser and exhaust tips being different.

Anyone do this already? Ordinary this would be up my alley, but like the way the non functional GLS tip look. Haven't seen the AMG in person.

I did it on my 2020 GLS580 and it was more work and parts than I anticipated. The exhaust won't go through the openings correctly so you must modify the exhaust at the muffler to exit the opening. You can reuse the main section of the bumper cover but the side wings must be changed too. All the GLS63 parts were $2500 plus labor. I have all the original X167 parts for sale if you want to go with the original. I will give You a great deal if you pay for shipping. You can private message me if interested.

GLS580 before adding AMG bumper new parts on floor.
Had to add side wings also - not shown.

Thank you for this! Very helpful! I would definitely be interested in your take0offs, but I need the blacked out night version. Still waiting to hear the cost differential for the GLS63 version compared to the GLS450. Also not sure if it will matter that I have the turned down exhaust pipes that come the non functional tips. Hopefully it won't look weird from behind.
