Just for comparison Michel, both my Boxsters are 3.2's and both have the same system as yours albeit the pipes run along the "top" of muffler so can't be seen.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Nothing too much to see.. as yet .. but hope to have it done over next few days
and its all been done before
Have been trying to get my hands on some early Boxster boxes and exhaust pipe to play with
ill get it coated later . to those who are getting things coated , advised by a local guy to me , titanium finish due to one of the chemicals used currently not available
first mod 1.5inch Pedro Sport Exhaust/fister mash up
and a bit of old skool bending - sand in the tube.

Blk one sounds like a water buffalo been fukd... hoping this mod, a little more refined
We’ll see next week once bolted up
blk 996 looking for better valves and may try do something with the bypass too make it more sonorous - particularly at idle /parking speeds...some have claimed it offensive
Finally got the first iteration bolted up . got it done without removal of the bumper cover
Not 100% convinced, though does do it nicely at 4K onwards - took it for a night outing down through local river roads.
As for drone will have to wait for the next highway run.
Whilst everyone e says this is a version of the PSE, as I’ve never heard one up close with the bypass open cannot comment.
if anyone has n original lPSE let me know. please.
Next version I think is bimodal
I’m definitely getting a hoist.
can’t seem to directly link the Vid. .
so hit the image and it’ll direct you
before
after
I can conclude by saying that the 1.5 inch bypass mod is quite Loud .
Going to install a baffle to see what /if any difference it makes
next version will have a valve and or go back into the muffler similar to porsche sport exhaust .
Just for comparison Michel, both my Boxsters are 3.2's and both have the same system as yours albeit the pipes run along the "top" of muffler so can't be seen. One has 3/4" pipe. The other has 1" pipe and 1" holes through the baffles via each tailpipe. They both sound pretty similar to yours at idle but the 3/4 is a bit sharper and barky at mid high revs than yours, and the 1" is very similar to yours but deeper and better sounding deeper at revs than my 3/4 one. Neither drone at any speed and I'm happy with both
Here's the exhaust sound Michel, sound here is pretty accurate:

Fetching info...
Yep, 1" pipes welded from exhaust pipes into tail pipes,
And also 1" holes in all baffles.
Done by punching sharpened 1" x 12" bolt (Bunnings) inside the tail pipes. Don't try drilling as it is a PITA and will take you an hour of frustration.
Try and hit the bolt in as best you can at a 90 degree angle to the muffler as the first baffle is curved.
Complete the first application of "punching" with sharpened 5'8 x 12" bolt and then repeat with 1" bolt.
Don't hit the bolts in as far as possible or you'll go through the back of the muffler, only go in as far as the bolt head level with the end of exhaust tip, maybe even not that far. iI's a series of hitting the bolt in 3 or 4 inches, then wobbling wrenching it back out, then hitting in further, then wrenching back out etc etc.
Cheap good noise!
I’ve got a second and spare muffler
Which I will do the CRiOS mod.
As well as working on a manual valve. Cheap and bimodal… Kind of suits my personality
🤭
😅
I’m still really keen to try and locate an early 986 Porsche sport exhaust . Want to cut it open to see what they actually did
Anyone have anything?
Sorry, no.
I'm a prisoner atm. Trying to get the property ready for sale.
I have a pretty good phone atm. Seems super clear.
Give us a ring if your keen to try? I'll lite it up.
