Tip to solve PSE exhaust droning noise in 5 minutes

Recommended Posts

Hi all,

Being fed up with the droning noise I had between 3 and 4 Krpm I decided to take a look seriously at it

I first thought it was coming from the tailpipes, no no, they sound like an empty tin can but no they are not the cause

I remembered having read about potential break of the exhaust pipes reinforcement ( since there are 2 of them on the PSE), that reinforcement is a thick piece of metal that kind of wrap up the pipes together, I really looked carefully a couple of time before but could not find any issue, when taking away the tailpipes i could see it better and it was clearly broken at 2 places on the 2 sides, this will require welding which I am planing to do

But

To be sure that I am not going to weld for nothing I decided to open the crack and put some silicon ( loctite 5940) to kind of dampen the noise

The good news is that it works and it lasts, silicon will stand high temperatures and will stand time

This is now day and night for me, that droning was just annoying, I am not ashamed to rev in public anymore :D

This quickfix could be a solution for those not wanting to weld and it takes maximum 5 minutes

I am planning to do the welding and will document it in the DIY section

Picture from ebay, the reinforcement can be seen just above the big pipe

      I am looking to shave some weight off my 02 with factory PSE. My question is,will a fabspeed ( or any) muffler work with the factory PSE set up? Is it just a matter of removal of oem and replacement with aftermarket? plug and play as its been called? Thanks in advance

      Hi all, 
      This will be my first post, thanks for a great forum ! 

      I've recently purchased a exhaust system from Design911 in the UK which has the valvetronic function on. This is said to replicate the PSE which my car does not have factory installed. 
      Wired it up and put the vacuum hoses, tested the system and it works fine.

      Over to the issue for my car:
      When starting up the car, the neutral positon of the valves is open, which means a lot of noice from the exhaust. 
      When switching this by the solenoid, sending vacuum into the system and the valves closes. This means less sound. 
      But when the valves is closed the car wont run properly at the RPM range of 5500-7000 RPM's there is also fault codes for misfire on cylinder 2.

      The strange thing is that this works perfectly when the valves is open. I've tried two differnet vacuum sources, into the ressonator and also for the left hand side cooling system vacuum solenoids. Without any differnce. I tried to run vacuum directly to the vacuum actuators on the exhaust without any difference and also tried manually applying vacuum and using a one way check valve to keep the vacuum while not connected to the cars vacuum line. No vacuum leaks, no fault codes when driving with the valves open.

      Same result every time. So have anyone had some similar issues to their car ? 
      Thanks in advance for any help !

      Help - i have a 2003 Boxter tiptronic s - in great shape other than a shrill loud noise like a Kazoo that only happens above 78mph - it sounds as iff coming from around the mirror area of the windscreen but then occasional sounds like its coming from the speaker area passenger side - that being said could be sound transference. Read a number of blogs about badly fitting windscreen so put tape over top rubber seal and body but still there - - as a say like a kazoo at 78mph with hard or soft top - absolutely driving me mad - any help gratefully received.

      I just bought myself my first Porsche, a 1998 Boxster.  I have an issue with the soft top that I'd like to get some guidance on.
       
      The top goes down smoothly with no issues.  It also comes up smoothly until it is nearly all the way up.  Just before the dashboard Top light goes out, there is a pretty sharp metallic twang or snap.  It did this when I was looking at the car before purchase, and it did it again this evening when I put the top up after driving the car home.  I'm assuming it's getting caught on something but I wonder if anyone might have suggestions on what to look at given the late point in the cycle where it occurs?
       
      Thanks!
