Reinstalled the FabSpeed Supercup yesterday as I wasn’t particularly satisfied with the way it had gone together before with the mounting bracket. It seemed like it would be pulling the muffler down putting tension on the heat exchangers/test pipe which didn’t seem ideal to me. Also the exhaust tip seemed to stick out unnecessarily far and looked a little too much like it belonged on a Honda.
Take the various bits apart and get it all aligned the way I think it should go and then reassemble the mounting bracket. It seems like the mounting bracket sits too low so I use a stainless hose clamp and put it around just the lower muffler portion and weave it through the 911 cutout on the mounting bracket and tighten it up. That seems to hold the muffler where it needs to be and doesn’t put tension on the rest of the exhaust system. Then I tighten up the clamps that hold the various bits of the muffler tube/exhaust tip together.
One recommendation I will make is cutting the bolts down shorter on the clamps to minimize the length. You could say it’s for weight savings (every once counts right?) but the reality is that it’s way easier to not have to use deep sockets to tighten things down. I also used stainless bolts/nuts with nickel anti seize for the mounting bracket and flanges because I was annoyed at the oddball size copper nut bolts it came with. Then I cut them all down to min length with a Dremel.
