Thanks Killer. One could also tack weld the reinforcing plates to the pan so they don't move, might be overkill, I just like welding metal. PM me if you have any questions when you do yours, I have dimensions and such that may save you some time. I am not familiar with the Supertrapp stuff at all. Your other post was talking about Flowmaster mufflers wasn't it? Are they the same company perhaps. I had a friend who had a Supertrapp on his enduro bike and it was awesome and adjustible by removing discs within the muffler. Great piece it was. If they make something to replace the Fabspeed muffler bypass based on that design and theory then I've got to see and hear it.
Kato...No the shield came off my original sensor. It's stainless and cleaned up like new with steel wool. Someone must sell it out there. The muffler bypass is not that loud to me, again I think it's Fab-U-lous.
Sound is each to his own.
I contacted Steve Wong about a chip and I know a few of you were interested in his comments. Here they are:
Thank you for your interest. The only chips I supply for the 84-86 Carrera
now are the 4k chips. If your DME is not already 4k enabled, it will
require you to perform the conversion by moving the jumper, or the car won't
start. The 4k software, as used by Porsche after 87, provides the car with
much superior throttle response that the cruder early 2k software is
incapable of. In addition, the sub 4k lag of the stock programming is
eliminated, power begins as early as 2000 rpm. The chip you'd require for
your setup, would be the chip for the sport muffler/premuffler setup,
designed to work with either the stock muffler or a sport muffler, as
additional fuel is provided if an owner does perform additional minor
exhaust/intake modifications. The chip should also work with the muffler
bypass you are using, however other than custom programming, I have not
specially programmed for a muffler bypass, as you are probably only the
second person who has inquired over the years about using such a setup -
must be very loud I'd imagine. Primarily the differences in the programming
of the sport muffler/premuffler chip is the remapping of additional fuel
expecially in the low/mid range part thottle region that without, can lead
to excessive exhaust popping and backfiring from lean mixtures of a freer
flowing exhaust. The top end fueling is also increased for the additional
flow from the exhaust mods. You are welcome to try the chip, and return it
if it doesn't work out for you for any reason. If you have any other
questions, or if I can be of further assistance, feel free to ask me.

Best regards,
Steve Wong

Nice offer, how can you go wrong. I am surprised no one has asked about a chip to accomodate a cat and muffler bypass combo especially for track use. I'll give him a buzz on the phone and chat a bit. If new news arises I will post it.
