Ideas to quiet 06 S that sounds like race car

Recommended Posts

Looking for suggestions. I have an 06 Carrera S Cabriolet that came with AWE headers, cats, and mufflers. It also has a performance air cleaner system with a conical filter in a sealed plastic housing. It sounds awesome on a track day but is too loud leaving the neighborhood @ 6:00 am. I purchased a set of factory mufflers and installed. This changed the sound very little. I want a little performance sound but it sounds like the flying lizards RSR when I get on it going under an overpass. I would rather drive fast and quiet, no need to let the police know you are coming. Is most of the noise coming from the high-flow cats? If so, could they need rebuilding or do I have to go back to OEM? Am I correct in thinking that headers should have very little to do with noise level?

Most guys are trying to get your sound! Might need to go back to OEM stock, but it won't be cheap. Did you just recently buy the car? See if the seller still has the OEM parts. That's why sellers usually keep these OEM parts when doing aftermarket mods. Because the next buyer/owner might not like it.

Be careful with that aftermarket air cleaner.

I bought the car more than a year ago. I asked at the time I purchased and the car was traded in with the performance parts and no OEMs included. I figured stock mufflers would take care of it and finally got around to finding a used set and installing them. That change made almost no difference, I was really suprised.

I know to be extremely careful with not putting too much oil on the filter.

A lot of your sound is coming form that conical air cleaner.. It has a similar effect as the K & N set up.. If you went back to the stock airbox that should tone it down quite a bit. I'm sure you could get one from a dismantler. Or ask around on the forums.. Someone may have one laying around..

Hi, I am very surprised that the factory mufflers did not do the Job, a lot of noise is coming from the air intake, this is why Porsche has a kind of muffler on the intake ( this is where you have written porsche on the silver intake manifold ) so getting back to a normal airbox is what you need ( get it on ebay )

Installed the OEM air filter housing. Made a noticable difference. Sounds just about right now. Definately can tell it is not completely stock without being obnoxious. Thanks for the advice.

Great, don't forget that you own a wolf in sheepskin so every time you will open the throttle the "dark side" of the car will come back

      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 !

      Hello there, this is my first post here and I’m writing because of problem with my boxster.
      Today in the morning I’ve started my 2002 boxster and noticed strange sounds from the engine/ rear side of the car
      It’s a metallic, grinding sound like a loose piece of metal or something like that
      Sound disappears when you press gas and comes back once you loose the pedal, I don’t know if it changes while engine is warm
       
      Also, check engine light shown up yesterday, when I connected my BT OBD2 there was no error code.
      I came with that to workshop also, and they said it’s a catalyst efficiency error.
       
      I’ve had that error code a while ago, I’ve replaced mass air flow meter and check engine light disappeared. 
      I think it might be a problem with maf again because I bought not the cheaper, not the original one, but why are there these strange sounds? I’m worried about this. Could it be catalyst this time? Or again should I replace maf? This time I’ll buy original one.
       
       
       
      here are two Videos I made
       
       
       
       
       
      Also I’m sorry if you can’t understand something, my english is not perfect.
      Thank you for all replies, I hope we will solve that problem together

      Hi all I’ve just found this forum tonight and thought I’d ask more experienced users what they are getting power wise after a remap, I’m taking my 08 CTT into Zensport tomorrow morning for a remap and I’m wondering what kind of power I should be expecting with the following mods I’ve had done last week prior to the remap.
       
      HAYWARD AND SCOTT EXHAUST WITH X PIPE, REAR BOXES, SECONDARY CAT DELETE, TURBO S STAINLESS STEEL TIPS.   IPD PLENUM    K&N PANEL FILTERS   AGENCY POWER RECIRC VALVES   Many thanks, Andy

      Have 03 C4S 55K mi. Both Cats going bad. getting CEL after every 50 to 75 mi. First from bank 1 and now bank 2. Have  basic Torque App software to reset. Pain in Butt.
      I track car about 3 times a year. No car mods. Run for fun.
      Looking to boost HP via new performance exhaust system. Thinking Headers and Sport CATs from Fabspeed. Factory mufflers are original, seem fine and would like to reuse.
      Along with perhaps new clamps, gaskets and a few new bolts, does anyone have advise on this?

      I installed a complete Used FVD Brombacher exhaust this weekend. Headers, Cats, Mufflers, 02 Sensors. When installing the FVD exhaust I noticed that the post catalytic O2 sensors were on opposite sides of the stock headers. (2001 C2 Manual) The leads were not long enough to go to the opposite side connectors. So I plugged them into the sockets closest to them. I was able to drive for about 30 miles until the CEL light came on. I noticed the idle was a little off, would fluctuate between the 760 - 860 range I think . Car drove fine. When I got back home I checked the codes.

      P01030 O2 Sensor Curcuit Bank 1
      P1133
      P1130 Oxygen Sensing
      P1126 Oxygen Sensing
      P0300 Random Misifre Detected
      P0306 Misfire Cyl 6
      P0304 Mis Cyl 4
      P0305 Mis Cyl 5

      02 Sensor Output 0.0v Bank 1 Sensor 1
       
      I hope you enjoyed my drawings. 

      Would this be due to the post cat O2 sensors be plugged into the opposite connectors? Plugs and tubes were replaced about 6K ago, all the coils looked fine. The 02 sensors came on the exhaust. Could this just be a bad O2 sensor? Would it be advisable to get the DME re tuned for the new exhaust?'

      Thanks!
