Yup - When you get to this point, replace the pair of OEM M8 x 1.25 bolts on the end of the tranny case with a pair of studs, which are shown in the picture below.

For the "u" pipe that connects the test pipes to the muffler, my clamps were very corroded, so I got these from Amazon:

For the "test pipes" - I'm not sure what comes with your brand or pipes, but a 2" Easy Seal is a better fastener than the little clamps that came with the Top Speed pipes I got.

Suggestion
Assuming that you mean the top bolt at the outlet end of the manifold, the best way that I have found is from the rear bumper area, using every single wrench extension that I own, one end plugged into the next, so to give yourself roughly a three foot long reach.

Since then I sent all my exhaust out for ceramic coating and that made it slippery I guess and the heatshield armor would slide around, where when on the bare stainless it stayed in one place so for now I am using just the ceramic coating and the heatshield is uninstalled.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
15 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

just curious if there are any tips or tricks that may be specific to the Boxster for an exhaust swap?
Little oddities that you found or learned when you swapped. Tricks that that you thought of along the way or after the fact. Things that were different specific to the Boxster.
Got my CircuitWerks catless mid pipe and the FVD sound version was delivered yesterday.
Hoping to get it all done this week.
Thanks for any input.
Yup - When you get to this point, replace the pair of OEM M8 x 1.25 bolts on the end of the tranny case with a pair of studs, which are shown in the picture below.
You can then "hang" the bracket on these studs while you sort the other fasteners, instead of needing three hands so to work with the OEM bolts.
Beyond that, mostly a plug and play swap. Use lots of penetrating oil on the other fasteners should this be your first time in.
Thanks - DM
That's a cool trick!
My advice would be, although folks have done it without taking off the rear bumper, it really isn't that much work to take off the rear bumper and it gives you a lot more room.
Clamps:
For the "test pipes" - I'm not sure what comes with your brand or pipes, but a 2" Easy Seal is a better fastener than the little clamps that came with the Top Speed pipes I got.
For the "u" pipe that connects the test pipes to the muffler, my clamps were very corroded, so I got these from Amazon:
https://www.amazon.com/gp/product/B00317DKWO/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
Another consideration, that I don't have any hard data on, is that the stock 2nd cats are shielded but the 2nd cat delete pipe is not and can radiate a lot of heat into the inner CV Boot, and also the inner rubber bushing on the rear LCA, so you may want to evaluate that and see if you want to add any shielding.
My first approach was heatshield armor as documented here:
http://986forum.com/forums/diy-project-guides/65692-use-heatshield-armor-stainless-zip-ties-test-pipes-shield-inner-cv-boots.html
Since then I sent all my exhaust out for ceramic coating and that made it slippery I guess and the heatshield armor would slide around, where when on the bare stainless it stayed in one place so for now I am using just the ceramic coating and the heatshield is uninstalled.
It is a hassle to work on these pipes once installed so if you were going to wrap, or do something like a Swain coating or a Jet Hot now would be the time.
Looking forward to the report after you get it installed!
On the Top Speed pipes at least, this connector does not replace a Porsche part, it is an extra fastener since OEM 2nd cat assembly is 1 piece, and the mid pipes are in 2 pieces, I think in order to facilitate a step down (or up, can't remember which) in diameter at the very end, and also maybe to help with fitment?. The clamp that came with the Top Speed pipes as a small little flimsy clamp, and many folks had reported that the easy seal made a better seal and helped prevent exhaust leaks.
I finely got the FVD muffler situated.
The problem I have now is, how the heck do you get at the bolts from the primary cat flange to the midpipe?
I just can't work it out. Thanks for any suggestions.
ETA: more specifically the top bolt of the triangle.
Assuming that you mean the top bolt at the outlet end of the manifold, the best way that I have found is from the rear bumper area, using every single wrench extension that I own, one end plugged into the next, so to give yourself roughly a three foot long reach.
You can then snake your long wrench in and around the various rear suspension bits and easily twist the wrench from the rear.
Looks super goofy, but it works very well!
