Talking with Highgate Mel, he has sold out of the last set of twin pipes but would be prepared to make another batch if I could get another 4 people to join me. The last system was great but alittle too noisy on the motorway. The new system could have larger rear boxes to tone the noise down slightly.|

If you are interested, please send me an email (link via my name) and I will start the conversation with Mel about price (The previous price was £300). As a rear box has just fallen off my old system, my neighbours would appriciate a response as soon as possible.
|15/04/2005 09:34:26||Alistair||I bet they would get more interest if they also offered just the downpipes & a front Y section that people could put a straight thru system on with whatever back box you fancy...|
|15/04/2005 12:33:50||Richard||Its all a bit noisey for my liking. I use Saab 900 and 9000 turbo boxes and it makes the same level of noise as a Saab turbo.|
|15/04/2005 17:49:25||Senor Burt||I got the front box from a Jetex/Simons system and built the rest from various bits. It worked well and sounded good too, without being too loud. I used a Peco straight through box from a Mini System for the centre box and a Cherry Bomb on the back.|
|18/04/2005 13:38:51||Steve H||Yes, ive made up my own systems before but found they never quite fitted as I would like and by the time I had bought all the bits, were not that much less than a proper system anyway. I also found the Highgates system to be the best ive had.(Standard-jetex-hybrid and Y pipe home made). Twin pipes suit the car as well.
Come on, there must be someone out there?
|18/04/2005 16:45:37||Richard||I built mine out of stainless based on the rally system but with the downpipe on a lesser curve as they mount the heads, its all got flanged bolt up gasketed fittings like the rally system. It does not rattle or vibrate. I will get some photos done on that as well sometime.
I remember Tom's car with the highgate system and it went like a fart (sorry Tom), we also put a Jetex on his other car and that made no usefull difference over the std system. Conclusion was one has no back pressure and too larger pipes that slows the exhaust gases down too much and the other system has poor joining of the two down pipes. I made a small bore (not much bigger than a std down pipe) exhaust with a equal Y under the bulkhead and any std engine we throw in that car goes really well. I remember a std engine with fomoco having more power than Tom's car with twin choke weber and big bore system.
I am sure Tom would back this up if he had not turned into a 900 owner!!!
|18/04/2005 17:11:48||Richard||I would like to point out that it could have been the car that went like a fart anyway. I just think that you need some more engine mods to make the best of a large bore system, rather than bolting it on a std engine with small restrictive ports. Ideally you want gradual increase in bore to keep the gas velocity up and give a laminar flow.|
|18/04/2005 20:12:53||john wyatt||I think Tom's farting car maybe had more problems than a too large exhaust bore, I have driven various 96's with bigger exhausts and they always feel a bit better than standard, that said, I have just slight decreased the bore from Jetex size on my 1740cc 96 and initial impressions are that it feels a bit torquier, fingers crossed.
|19/04/2005 14:00:02||Steve H||Ive heard it said that you can patchy results on a standard engine with any sports system as you are still pushing out through shared small aperture flanges on the head. My engine has enlarged ports and flanges as well as a 1729 capacity and twin weber. I have a standard car as well and the difference between the two is very noticable.
And still no takers then....?
|19/04/2005 15:33:44||jonny||Just out of interest a place quite near me do custom stainless systems for any car to any spec, you drop your car off in the morning and tell them what you want and get it back at teatime, about 2 years ago they quoted me about £350 for a complete system for the V4, I never ended up getting one but my brother got one for his BMW, it cost £200 from the front pipe back and is very well made, if any interest I could find out if they are still on the go.
|20/04/2005 10:49:57||Alistair||I've had a Jetex on a standard engine and it definitely helped, better all through the rev range, but much more so with a 28/36DCD as well, even though it was only on an SAH adaptor!|
|25/04/2005 13:47:10||Steve H||Mel and Ken emailed me saying they had found a guy called simon who was selling a twin pipe sytem, but on contacting him, he had long since sold it.
I'm getting desparate. I paid this weekend to have a join clamped on.
Im looking for three others to join me and we can then get the system made to our own specification (quieter, better fit at the back, flexibilitiy at the headers to stop speed bumps and torque twist working the manifold loose.) Unless you all have stainless systems, you are going to need one eventually. Working together we can make it cheaper than going individually to the local pipe bender.
|27/04/2005 12:24:54||Iain||I'll have one. Put me on the list.|
|27/04/2005 13:00:42||Steve H||Fantastic. Do you have any requests for the specification?
And any more takers?
|03/05/2005 14:06:42||Steve H||Thanks Jon. How much was 'a fortune'?
Anyway, following a chat with Ken on Friday, it seems he will soon be in a position to make 5 systems, selling four to the people who we have got together and putting the other on the shelf. So if you might ever want such a system, speak now or forever weld up your own exhaust(!). The more in the batch, the cheaper it gets for everyone.
|04/05/2005 09:38:13||Jon||£900. Full stainless, 2 exhaust ports per head using existing mounting points and floor holes. Had it done in 1999 and still in mint condition.
|09/05/2005 13:38:09||Steve H||I presume you have twin port heads then, or have you done something strange and clever?|
|09/05/2005 23:10:39||John Wood ( "Woody" )||Steve H, I do not know which part of the country you are in, but in Nottinghamshire a number of works type rally exhausts were made by the guy who made the competition systems for Beechdale's Rally 900. I shall try to find his company name but he is based on Cinderhill Road, Bulwell about a mile from J.26 M1.
If you have an original to copy he can do it. Ask Neil Ryder of East Midland Saab. The quality of work was very good.
|31/05/2005 12:29:53||Steve H||Thanks John, The price will be interesting.|
