How to remove rear bumper???


Recommended Posts

I am planning to upgrade my exhaust system...headers, cats and mufflers. I looked under the car and it appears that I will need to remove the bumper in order to remove the old cats and install the new ones. Anyone done this??? I would imagine it's a simliar procedure to the one that would apply to other 996 models. I am planning(not carved in stone yet) to put in the Cargraphics R-exhaust system with headers, 200 cell cats(OBD2 compliant) and their sport mufflers. They tell me 20+ hp gain, but I am waiting for some proof, such as a dyno chart.... and final pricing. Thanks in advance for yur input... :jump:

I don't think you need to take the rear bumper off to remove the headers, cats and mufflers. You will need to remove the rear tires. The mufflers hang on a bracket held by three 13 mm nuts. Once these are removed and the sleeve on the cat loosened and slid out of the way the muffler can be rotated down and out the side. The headers and cats should be clear also.

Now the install... if that system shown in the picture is welded together at places the original parts are not then you may need more room.

Either way just remember not to tighten anything down until the tailpipes are centered properly in the rear bumper openings.

Thanks Loren...I believe the system is bolted and clamped together at the cats,headers and mufflers...So that is good news that the bumper can stay...One less headache. I will have to confirm w/ cargraphic that it is in fact bolted/clamped together at the connection points. They tell me that it's basically a plug and play system for lack of a better expression. My only worries now will be torque values for tightening the various bolts on the headers ect. I have a sneaky suspicion that there will be no instructions which seems par for the course with these german parts, so I may be asking you those torque value questions. Thanks!!! :D
