Can't see these on club site but some on ebay are pricey once postage is added. I thought they were made in the millions and fitted to various makes but couldn't find any locally. Called at the Car User shop nearby and took a chance on part number EMR001 £2.99. It was twice the width of the original but had a convenient moulding around the centre that I used as a guide to cut into 2. Offered up one half and it was a perfect fit and I now have a spare for less (just) than £1.50 :D :D

A Sprint has 7 of these rubber mounts, i've been using the EMR001 cut in half for several years now as the quality of the "correct" one is abysmal, even when bought from reputable suppliers like Fitchetts, I've had them snap when fitting and once fitted (IF you can make them fit) they are lasting less than 6 months.

Also the design of the originals only permits the use of the original mild steel exhaust's dished brackets, most aftermarket and stainless systems use carriers incorporating a steel rod which there is no room for in the "correct" rubber mounts, so they are almost doomed to early failure before you start.

Hence i've adopted the EMR001 as mount of choice as it doesn't have any of the problems of the original (and it's cheap) So much so that I have a dozen or so in stock at all times!

He makes and sells Superflex mounts Murdo.

I was actually the first person to buy a set and, shortly afterwards,
Chris's assistant phoned me to ask how I had got on with them or if I had any comments
but I hadn't actually fitted them so could offer no feedback.

:oops: Alas they are still not fitted, definitely this year though.....

Yep, I have had no end of trouble with exhaust rubbers for various cars. The big issue I keep encountering is the rubber is simply too soft and allows too much movement. Not only on the Dolly but I had an exhaust on a Rover 75 Diesel that kept hitting the body, till I fitted the proper xparts ones. Suddenly no problem, of course they cost about three times as much.

Just put a wide tie wrap loosely around the rubber mount and the problem is solved. It limits the movement and stops the mount splitting.

Yes, they work pretty well on original mild steel exhausts like the one pictured. You can see the U shaped hole in the rubber conforms closely to the U shaped channel in the mount bracket on the pipe. But modern aftermarket and stainless systems have a steel rod above a shaped piece which gives a much bigger and different profile and won't altogether fit in that U shaped hole in the stock rubber. It puts so much strain on the rubber that they either break during the fitting process or soon after. Nor have I found it possible to relieve the rubber satisfactorily (I DID try!)

If it needed a tie wrap, the factory would supply one. In truth, you could do away with the rubber and just use a tie wrap. I actually did this on a Sprint recently, which I took for MOT. When I left home, the original type rubbers though over a year old, were all in place and intact, on arrival at the testing station, 9 miles away, only one out of 7 was still in one piece, I had to strap it up to get it home and the ubiquitous cable tie (x6) came to my rescue. This car is fitted with a SS pattern copy of the original exhaust. It now hangs from 3.5 EMR001s, each cut in half, unusually for a SS exhaust, nothing bangs or scrapes! That's good enough for me!

Edit. Here are a couple of pics of a Rimmers (I think) SS system fitted to a Sprint I was working on last year but the style is now universal, even the club exhausts are like this. The top picture shows clearly the difference in profile between the original upper mount bracket (on body) and the SS exhaust mount (lower)

The lower pic shows a 1/2 EMR001 fitted, the larger rounder hole means the rod and plate bracket has room in the rubber. The whole thing admittedly DOES hang a few mm lower but it's not enough to cause a problem. Since OE mild steel exhausts are effectively unobtanium, we are all going to have to adapt, the EMR001 is a practical and viable solution and it's not expensive.
