Kenny Senior

I also have 7&8s as I prefer the look with the better filled arches. You do lose a little of the delicacy and feedback through the sterring, although it is still night and day compared to modern car with assistance.

£400 for the lot if collected.

I wish there was an easy, cost effective, off the shelf solution for a 3.6 in an earlier shell. I looked into for for a few years but found nothing to suit. If SSI made their backdate set with 41mm primaries I’d have gone that way and be damned if they were slightly undersized. I did ask them twice in the last 3 years if they were planning to make them but they said not. It seems bonkers that they’d make a set specifically for a 3.6 with 39mm OD primaries when they’re making larger sets too. If you have the time then a custom Turbo Thomas would likely be more cost effective than this Bursch set. I’m happy with what I’ve got now though.

Another thought on those big bore SSIs is that they don’t clear the chainboxes on a 993 either. Possibly also a 964 lump. They’ll be an improvement on a sportier 3.0 though.

41mm OD will be about 36mm ID. No good for a 3.6. The Bursch are 45.5mm or so OD and 40mm ID or thereabouts. I have driven the car with the new Bursch exhaust and it’s great, although with the flaps open it’s pretty antisocial. Hoping to get some videos this weekend if the weather stays nice.

I've not even driven yet. Still a couple of bits to do like fit the rear panel around that silencer. Last time it was on Wayne's rollers with the old exhaust it made 303bhp, but many people throw pinches of salt about those figures. I'm hopeful for a few more horses, but it doesn't worry me. It's more the sound I'm after. The 993 headers are unequal length and the car sounded angry most of the time. I'm hoping for a bit more of a rich, full noise.

I didn’t pay list and $1.3 to £1 helped. I doubt a full bespoke system would have been much cheaper, especially switchable. Expensive, but options for this engine in a SC shell are very limited. It was the last “compromise” on the car so I’ll be glad to have it finished.

When I got the 3.6 installed I struggled to find an off the shelf exhaust to suit. SSI make a set with 44mm primaries but they’re for earlier cars and they clash with the 993 chainboxes. They also make a set that's supposed to be for this 3.6-into-an-earlier-shell application, but they use the same 39mm primaries as their sets for 3.0 and 3.2. I was worried that with primaries smaller than the exhaust ports on the Varioram I'd strangle the life out of it, especially at higher revs. As a stop gap I had my old 2 in silencer butchered to match up to the 993 manifolds (see for sale section 😁 ) and I've been running it that way for the last 3 years. I'm not convinced it's flowing as much as it needs to though and it's made the exhaust path very short. I considered going to see Turbo Thomas, but I don't spend much time in the UK these days and he always seems to be booked up for months. Recently Bursch have started making their system in 1 3/4" with (small) heat exchangers. This matches up to the ports pretty much perfectly. It looked a lovely bit of kit but outrageously expensive. I got in touch with Sierra Madre and managed to get a bit of deal. The 3-1 collectors look nice and the whole thing looks like it’ll flow well. With the Y-pipes into the 997 GT3 backbox it’s switchable between quiet and loud or, more likely, loud or louder. It's now being fitted. I'm hopeful for a bit more responsiveness and a much nicer noise. I'm not so hopeful that the heat exchangers are going to keep me toasty on a winter drive, but some heat is better than no heat I guess. The mechanic informs me it’s been a pig to fit and there’s still some bits to sort. Looks nice to my eyes though. At least its another option for 44mm primary manifolds with heat if anyone needs it.

Sale price was £8810, so well north of £11k including buyer's premium and VAT. Ooof.

I have a pair of 993 headers with Bischoff flanges for sale. Could probably do with a clean before fitting but they're stainless from the factory so no rot. As a bonus, if you collect you can have the 2 in, 4 out silencer I was using for free. This is an Eisenmann silencer that had the original inlets cut off and some Bischoff inlets grafted on at angles to suit the 993 headers. The whole lot could be fitted to any aircooled engine although the flanges on one side will need cutting off and rotating 90 degrees as 993 studs are different. The silencer doesn't do much silencing due to the angles of the inlets, but could be used for parts for whatever application you're doing. £500.

I went through this during my backdate. The Cobras I had felt a bit cheap and flimsy. They weren't too comfy either. I bought a pair of tatty sports seats from Jevvy and got them retrimmed to suit. They're the comfiest car seats I've ever sat in and I love the deep bolsters. I've done big mileages in them since fitting without any discomfort.

How were the Yokos? I'm not that impressed with the Michelin PS4 I've fitted. Just not so much outright grip as the previous Continentals.

This. I'm sure there may be others capable, but Chris and Pete at Center Gravity are the best in the business. They've set up a few of my cars over the years.

My advice would be to not touch Emerald with a barge pole. They left my car detting badly despite two separate sessions on their rolling road trying to get PMO ITBs to work. Whether it was their inability to get their ECU to fuel correctly, or the ECU not being up to the job, my patience gave up and I fitted a Varioram engine instead.
