Poly Exhaust Mounts Now Available

Having now tested these exhaust mounts for fit, they have also undergone successful road and track testing and we are pleased to be able to offer them for sale.

These uprated exhaust mounts are manufactured in a high temperature polyurethane material with a Shore A hardness of 67, compared to the original rubber mounts which measured 55 Shore A.

They are much stronger, more durable, with much less flex due to the material type and a reduction in the size of the centre cut-out, offer far greater resistance to tearing and rot resulting in much less exhaust movement. OE Exhaust Rubbers are prone to cracking and failing, quite often causing an exhaust knock often most noticeable on start up.

An inexpensive and worthwhile upgrade. The number required per car will vary but this mount will suit Astra G, Astra H, Vectra B, Vectra C, Meriva A, Meriva B, Signum, Omega, Corsa C, Tigra B, Zafira A and Zafira B where 90466688 is specified.

Uprated Exhaust Mounts

We have noticed that the universal exhaust rubber/mount used on many many popular Vauxhall/Opel applications including Astra H VXR, is not very strong and over time has a tendency to perish, stretch and split, consequently requiring replacement. Often failure can occur quite quickly, especially on a modified car.

Added to this on performance models and modified vehicles with larger diameter exhaust systems, any exhaust movement in the rubber exhaust mounts can lead to knocking from time to time, especially when the mounts start to fail.

Have you ever noticed the occasional knock on start up, or from time to time when driving? This could be an indication of the first signs of weakening rubber exhaust mounts. So worth giving them a checkover at the first signs of a problem.

So we approached our friends at Powerflex to look at a solution for us. Because none of their universal exhaust mounts were close enough in size to the Vauxhall/Opel rubber mount, they set about making a polyurethane exhaust mount as a replacement.

They have looked at the OE item and manufactured a replacement, which is slightly larger overall but retaining the factory dimensions internally, in their high temperature polyurethane material with a Shore A hardness of 67, compared to the original rubber mounts which measured 55 Shore A.

The result is a much stronger, more durable mount with much less flex, offering far greater resistance to tearing and rot. Ideal for any standard or modified fast road vehicle; these exhaust mounts are equally at home on the track too.

An inexpensive and worthwhile upgrade. The number required per car will vary but this mount will suit Astra G, Astra H, Vectra B, Vectra C, Meriva A, Meriva B, Signum, Omega, Corsa C, Tigra B, Zafira A and Zafira B where 90466688 is specified.
