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 Quote Link to comment Share on other sites More sharing options...
michel Posted 25January, 2021 Author Report Share Posted 25January, 2021 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 Quote Link to comment Share on other sites More sharing options...
michel Posted 28January, 2021 Author Report Share Posted 28January, 2021 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 .

Troubleshooter Posted 28January, 2021 Report Share Posted 28January, 2021 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 Quote Link to comment Share on other sites More sharing options...

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?

firstone Posted 8February, 2021 Report Share Posted 8February, 2021 I did the CRIOS method to around 20mm, removed the right angle cats, then added 100cell or 200 can't remember. Sounds great. Not loud but nice. Quote Link to comment Share on other sites More sharing options...
