Hi 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 😊

Hey Loren, Please help me. CDR-210 BE 2282 V5011117 Thanks in advance.

A 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.

Yes.

I'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?

Hey 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… sigh

I 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.

Probably 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? MY 2000 base Tip Link to kit: https://www.pelicanparts.com/More_Info/RENM67HARDWARE.htm?pn=REN-M67-HARDWARE

I didn't want to say anything because I was afraid of disturbing the force, but since the window issue started up again yesterday screw it I'm telling my story. 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.

Has 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.

It might be helpful if you have a photo showing the fault code numbers. Thanks!

Used sets I haven't found, the Dido ones I know well, since I actually have one set but don't really like them. What I would really like are the ones in the photo I posted.

Back in the day, I remember them being optional parts. There are currently multiple used sets on eBay, and there were some aftermarket suppliers as well, such as an outfit called Dido Tuning :

Do you know whether these were sold as add on parts or only sold as a cluster? Any P/Ns?

They may no longer be available due to the part's age, which is not uncommon. You might check with a dealer to see if any still are on the shelf somewhere in the system.

Are/were the silver rings ever available to buy? I never found them available for sale. This is a Porsche stock photo in the Porsche Shop entry for the leather key ring in the photo, so I suppose this is 100% stock, and they would be available either as a factory option for the cluster or separately? Can't find any associated P/N anywhere though.

Base brake discs: front - 298 mm rear - 292 mm S brake discs: front - 318 mm rear - 299 mm While the S calipers might fit the pads would hang over the edges of the disc rotors. So I doubt they are S calipers.

I have a 2.7l 986, but I believe it is fitted with S calipers (they are red and say Porsche on them so haven't been repainted). The brake discs, however, have the diameter measurements of the base discs. Is it possible to fit S calipers on the base discs, or have I just mis-measured? Thanks!
