More horsepower? Better sound? You are not going to get much more horsepower out of a normally aspirated Porsche. Maybe 30 BHP with all those options. That's a lot of money for very little that you will feel. For sound nothing beats or matches the Porsche PSE system to my ears. I would rather listen to a good PSE than the radio.Wed, 08 Apr 2026 15:57:35 +0000I don't see why it wouldn't work, but overspeed pulley adds a complication and potential future failure point that the fixed pulley does not have.Wed, 08 Apr 2026 14:01:28 +0000I have a 2000 tip base and appears to be a fixed type pulley with the nut. Can a freewheel style pulley be put on in place of a fixed (for a Tiptronic), or do I need to reorder a fixed pulley?Wed, 08 Apr 2026 05:30:40 +0000Took the belt off and ran it for a few seconds. Chirp completely gone. Ordered a set of pulleys and a new alternator pulley, and belt.Wed, 08 Apr 2026 05:26:57 +0000I disconnect the GPS antenna permanently. The date is ok now. But once the car battery is replaced, i will have to repeat the whole process again to set the date.Wed, 08 Apr 2026 01:47:04 +0000Try 2564Tue, 07 Apr 2026 16:32:27 +0000Good morning Loren, Had a very quiet drive this AM after swapping out my radio display. CR-220 type: 4362 SN: Y5021762 Thanks in advance, RPTue, 07 Apr 2026 15:47:58 +0000Hi All, I have a 2008 987.1 Boxster 2.7l, which I use as a daily and for spirited driving – but not track use, here in the United Kingdom. Needing to pull on your expertise.. I’ve spent hours trying to understand a few things at once, but not getting very far..!! forgive me if I make a hash of explaining my questions.. I’m going to need to change out my headers and exhaust soon, followed by a plenum upgrade and ECU stage 2. My car has the PSE system – which I’ve grown to like as there are times and occasions when quieter or louder are appropriate. I’d like to get a setup which, I understand, is a ‘valved’ system. Are there valved systems which can be connected up to the existing PSE to be able to operate from the switch just like the original system? If so.. please can you tell me of any systems which would work? I understand my car has 4 catalytic converters.. each side having one built into the headers, and one in the ‘back box’ section – is this correct? Are the header-cats known as the PRIMARY cats, and the back box cats ..the SECONDARY cats? Is a ‘DECAT’ exhaust meaning a CATBACK system which does not have cats in the back boxes? Is it possible to fit headers without cats – that would still pass an MOT, or is it a case of getting what I’ve read about.. 200 cell cat headers? What would be the preferred complete set up? No header cats? No back box cats? Are different manufacturers of headers and cat back exhausts using THE SAME dimension pipework? I’ve probably not been very concise, but hopefully you ‘get’ what I’m after.. ideally I’d like to get some headers and exhaust which sound nice, fit together size-wise, reduce where possible restrictive cats, is valved and can be connected to original PSE vacuums/wiring etc.. but also that will be beneficial for a planned plenum upgrade (deciding between 74mm and 82mm with GT3 throttle body) and ECU stage 2.. hopefully, all brought together to work complementing each other by some tuning wizard who I haven’t located yet..!! I do like the sound of the Borel exhaust – but I don’t think that is a valved system. I’d like to get something which sounds deep and throaty – like a 1980’s air-cooled 911..LOL.. , rather than high-pitched and raspy. Any insights, recommendations or general advise or help I’d be really grateful for, please. Many thanks 😊Tue, 07 Apr 2026 01:48:46 +0000Try 5430Tue, 07 Apr 2026 00:04:54 +0000Hey Loren, Please help me. CDR-210 BE 2282 V5011117 Thanks in advance.Mon, 06 Apr 2026 23:42:45 +0000A chirp is commonly a loose spark plug or an overtightened spark plug that is now cracked. If you have a scanner it should tell you which cylinder is miss-firing.Sun, 05 Apr 2026 19:45:08 +0000Yes.Sun, 05 Apr 2026 15:33:30 +0000I've had the front driver seat out a couple of times (once, after I bought it as it came with a quarter jammed in the guide rail that I had to get out and the other time to actually replace the seat with a better condition on I picked up at a swap meet) and don't recall there being any box under the driver's seat, but that was a couple of years since the last time I had it out. Should I be able to "feel" the box if it's there or use my borescope to see it?Sun, 05 Apr 2026 11:54:27 +0000Hey Loren! Miss seeing your name. Haven’t been on forum in a while. Your pic makes sense. Guessing they include the hardware for those, but are not used in my application. good deal! now to finish chasing this pesky “chirp” I’m hearing post-install… sighSun, 05 Apr 2026 03:25:30 +0000I don't recall Boxsters have heat shields. The engine is a Boxster faces 180 degrees from that in a Carrera so the exhaust does not pass by the cylinder head. Here is a diagram of the 996 layout with the heat shields marked by the arrow.Sun, 05 Apr 2026 02:44:33 +0000Probably a dumb question, but I’m mid-install of the Rennline ignition coils and I got the matching hardware kit that goes with them. The 2 longer bolts per coil make sense, but I’m confused on the 4 bolts and “spacers” that come with it. The kit says these are for the “exhaust heat shields”, but I’m not visually seeing where these would go or if they are even used on my car. I do have aftermarket bypass pipes and muffler so maybe that matters?

A year ago I went all in and replaced both the regulator and door harness and for two days the problem remained. On the third day it was cured! It's been a glorious year driving my fully functional car. Nothing could get me down, even when I had to pay the dealer $720 for a god **** key fob. I was totally infatuated. Until I took a corner the other day and the window jumped up and down once again. Although it still seems to act on it's own randomly, I seem to be able to force the issue by pushing on the door card between the speakers and the grab handle. I'm guessing some kind of wire or grounding issue. Or possibly demonic possession.Sat, 04 Apr 2026 19:43:04 +0000Has the car been in an accident? You have two short circuits on the starter relay - check fuses and inspect the relays for damage Also, check to see that the MAF is plugged in and not damaged.Fri, 03 Apr 2026 18:46:13 +0000TanksFri, 03 Apr 2026 14:12:47 +0000Fri, 03 Apr 2026 14:11:41 +0000It might be helpful if you have a photo showing the fault code numbers.
