I'm new to using a blog so bear with me. I have a 2017 911 4s cab with the standard exhaust. If I push the sport button it gets louder. on my corvette ZR1 I added a switch to open the butterfly valves for full exhaust and wondering if that can be done with this car?  or other ideas on how to get a little more sound?  Thanks

You would need the optional sport exhaust for that. I added it to my 2013 Carrera S and it was the best money I've spent on the car - totally transforms it.

Is there a way or what is the procedure using a PIWIS with update . 18.1  to tell a 991.2 ( w/o sport exhaust ) that it has sport exhaust?

If you push the button and it gets loader, then you do already have PSE, just like my car. Enjoy!

      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.

      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
      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?'

      I've recently started changing exhaust components to obtain the exhaust note that makes me smile on my long drives to work. First I purchased a used Instant-G muffler and C pipes from someone who had a 3.6l conversion. In fact, I think this exhaust system was made for the 3.6 conversion as a kit. It sounds very nice and 2.25 inch C pipes and inlets -- low tone sonics. I had a drone at 3K that was quite loud, but a lower tone, still good sound -- but made me tired on long drives. I decided to install 2 inch down pipes from the stock headers to the 2.25 inch C pipes. The drone is completely gone. In fact, I miss any sound without throttle. Albeit, it's a nice departure from the drone sound, it would be nice to have some sound when I let off the throttle. When on the throttle it sounds very nice!! And surprisingly, the car feels much less strained when accelerating. It's like a different car, like it can breath now. Lots more power even at lower RPM, and throughout the power band. I really like the way it easily accelerates at any speed.
      So, a few questions:
      1. How can gain back some of the lost sound on deceleration? -- Not a top priority, but if changing something means not having the power the way it is now -- then not worth it. 
      2. Since the system is now essentially restriction free except for the minimally baffled muffler -- is this in any way harmful to the engine? It feels like the motor runs easier with less strain.
      3. I tied the secondary O2 sensors up and out of the way. No CEL, but is this some how harming the ECU's attempt at a stoichiometric O2/Fuel mixture. I'm assuming that no default program is triggered by the lack of proper signal these are now sending to the ECU.
      4. What do you think of this setup?
