Covers all Carrera, and GT3 cars Removal -- 1. You will need to lift the car high enough that you can safely get underneath (you do not need to remove the rear wheels on most cars but most folks find it easier with the rear wheels off). 2. Loosen the 2 bolts (each side) on the sleeve that connects to the cats and then slide it towards the cat. (You might want to spray these nuts with WD40 first so they will loosen easier -- just don't spray the O2 sensors). 3. Crawl under the car and remove the 3 bolts that hold the muffler mounting bracket and the muffler in place. These can be a bit of a reach and not much swing room for the wrench. 4. Rotate the muffler down and out from under the car. 5. Remove the tailpipe by loosening the clamp as you will need to use them on the new mufflers. Install -- 1. Attach the tailpipe(s) to the new muffler but do not tighten them yet. You will need to adjust everything later before you tighten them down. 2. Rotate the muffler up and on to the 3 bolts and lightly tighten the nuts. 3. Slide the sleeve off the cat and realign it on the muffler and cat. Again, don't tighten the nuts too tight yet. 4. Align the tailpipe so that there is about 20 mm distance from the top of bumper cover and equal distance and length all the way around. Then tighten down all of the nuts. The tailpipe 22 ftlb. (30 Nm ), cat sleeve 34 ftlb. (46 Nm), and the muffler bracket 17 ftlb. (23 Nm). 5. Repeat on the other side and you are done! (updated with torque values and images 26 Jan 2004)
