Things have been busy with some traveling and I hadn’t driven the 911 in a few weeks. I had ordered a FabSpeed Supercup from our host two and half months ago but apparently the 2-3 week delivery time was a bit optimistic. It finally arrived yesterday:
After going through everything a couple times and then looking on Fabspeeds site it isn’t exactly clear how it mounts up. The instructions on the site appear to be for some other type of system and doesn’t offer any help. Google some images and eventually find a pic of what this thing should look like once installed from some other performance parts seller. Not a great pic but enough so that I can now make sense of it.
Start bolting it all together and the bracket seems to sit too low. The strap for the muffler seems like it wants to pull the muffler down and put additional tension on the headers/heat exchangers through the test pipe. It also seems to want to pull it down to touch the bumper valence thing and I would like them to not touch and the muffler to sorta be in the middle of the bumper shell.
After tinkering with it for a long time I decide to take it apart and use only the one bolt to make the bracket sit higher. It may not be correct but at this point I’m irritated at the lack of information available and I’m gonna do it my way. This is how it now fits before I put the strap in place.
I drilled another hole to add a second bolt to hold the bracket together and tightened everything up. By this time it’s nearly 11pm and I’m drowning in sweat because it’s really hot here and my garage isn’t air conditioned.
This morning fire up the 911 to drive to work and it sounds incredible. It’s everything I like with having the straight pipe confit from a few months back but isn’t deafeningly loud. I’m going to probably take the whole Supercup exhaust off this weekend and rework the mounting bracket. The bolts for the clamps/strap are excessively long and in general I’m going to tidy up the whole thing. Thinking replacing the strap with a sorta bolt clamp setup between the two muffler chambers so I can adjust the bracket… to be determined.
In all it sounds great but it definitely wasn’t as straightforward as I expected to install.
