Nigel - similarly, epically loud sounds like the effect we're after (though perhaps not after a 2-hour drive...), but would "lengths of pipe" meet with plod's approval? Shouldn't be a problem - at the end of the day, the backboxes are just a length of pipe anyway - its just that one bit is very fat. You're simply replacing the fat bit (ie the silencer) with a narrow bit. As long as it's secure, plod should have no issues (unless the noise is breaking windows, setting off alarms at 200 yards and causing kittens to go deaf.... )

Hmm. Some research indicates that exhaust noise is a very grey area - legally speaking. This information from the VCA suggests 74dB is the limit for new petrol on-road cars. It also reckons that a car should not make more noise than it did when the model was type approved. I had no idea that people were such killjoys! Might still try it anyway, just be sensible when in built up areas, late at night, etc. The issue for those trying to slap penalty notices on motorists is how to prove the infringement, given the difficulty of recreating the particular conditions used to take the original readings.

I think you are worrying too much about exhaust noise. Used to run my A35, with 5.7 sbc on the road with next to no silencing. never had any plod problems. currently driving around in totally un silenced 1641cc Volksrod. 4 pipes straight out from engine. again no probs from plod

The other major weak point is the Ford gearbox. A fluid change every 50-70k miles is essential. At least it uses cheap Dexron III and is easy-ish to do. I really would not try and get more power out of it as you will send that 5R55N to an early grave.
Drop links and ABRs rattle. New links and bushes and good alignment is essential for the car to feel nice. The front brakes are a bit small and don't suit low-friction pads. Buy the best you can get (Jaguar/Jurid 233).
There is a longer list of secondary problems that you might experience but the jaguarforum.com guys are pretty knowledgeable and friendly as long as you keep away from the political discussions!

Not convinced remapping an N/A is going to achieve anything but the lighter wallet might improve the power to weight ratio Heating: look into the heater distribution valve. Almost certainly dead (hopefully it has not taken the controller board out as well). Awkward job. Rear passenger door lock: Had that one. Crappy microswitch in the locks. I would be tempted to replace the lock sooner rather than later in case it decides to jam locked. Usually means destroying the door card to get in and makes a fiddly job even harder. Window regulators have some plastic parts that age and break. Can be cheaply replaced. Otherwise a complete new regulator is required but even they are not too much dosh. Btw, the adjusters in the headlights do this too and the headlight point down just in front of the bumper Again a cheap part but the bumper has to come off to take the headlight out for the minor surgery. I think the S-Type was very much underrated. Its deficiencies were not significant and now that it is old, the old looks fit. Look at an old Merc or BMW form the turn of the century and they look just plain old Edit: There is a control pack in the drivers door which might be the cause of the problems with the mirrors ...

We kept speculating as to how the Jag will sound in comparison to the legion of delicious V8's on display today. Time will tell - it's off to Pro Speed in a week... Hopefully, it may spend time in Flea's tender care afterwards...! To me, who values engine sound above car looks and handling dynamics, I'm drooling at the thought of how your Jag may sound. Never had a V8, although I'm up to a V6. Who are Prospeed?

The first thing I will say about our Jag's exhaust saga is that the result is - unequivocally - fabulous. Unfortunately, I didn't record the subtle tones of the V8 before we took the car to Cardiff, so I can't do a before and after. We always intended to find a way to make the car sound better - why have a V8 and bark yourself? - and with the recommendation from Gripped of this Parish, we decided to get a bespoke system made up by Pro-Speed and its owner, Charlie. The idea was to have a system with switchable electronic valves offering butter-wouldn't-melt whispering on one setting and yikes-what's-that?! on the other. We duly delivered the Jag to Cardiff on 7th October, with the promise that it would be ready in a week to two weeks. The workshop looked a bit back-street, but hey, that's how true geniuses work. Whilst there, we selected some tasty twin oval rolled tips to complement the install. We finally got the car back last Thursday, after 2 trips to Wales in the intervening weeks where we had been assured that it would be ready, but it wasn't. Excuses included: - One of his workers had caught his hand in a chop saw and his parents were suing - Gypsies had broken in to the workshop and stolen our exhaust - Charlie had had to sack another of his crew, putting him behind schedule - Someone had suffered a heart attack in the workshop. Some or all of these may not actually be true. Either way, every time another hold-up occurred, we begged Charlie to simply pick up the phone and tell us. In the end, we were left feeling strongly that all was not well in Charlie's life. And we didn't get the twin tips... No question, the man can build an exhaust, but he needs to sort himself and his communications skills out. Anyway, here's the bit you've been waiting for... S-Type with new "normal" exhaust S-Type with "Blimey!" valves open

Well, what can I say. It does sound awesome. I also think those end pipes suit the car well. Sorry you had a poor experience along the way Jim. Having only used Prospeed the once, I can only go on my own experience which has been fine. I was also recommended them by someone else who is a proper tuning fiend. I hope you feel it was worth the trip. Maybe he bit off more than he could chew or as you say, there are other issues going on. Last time I saw him, he was wearing a back brace ! I'd like to hear another video of it under load driving past at full throttle !
