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.

Powerflex Exhaust Mount

Powerflex Exhaust Mount

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.

Note: This mount cross references to OE Part Number 90466688

Priced at £6.60 each

Side Gearbox/Engine Mount Fitting – Astra G/H and Zafira A/B

Astra G/H 2.0 Petrol Turbo, Astra H 1.9 CDTi, Zafira A/B 2.0 Petrol Turbo and Zafira B 1.9 CDTi have a gearbox side mount that is rubber and prone to failure.

Courtenay Sport approached Powerflex to devise a solution to not only improve the original factory mount, but also give it some additional support and to help reinforce it. In some cases where the original factory mount is not too badly damaged or split, the polyurethane insert can be used to ‘save’ the failing factory mount and prevent further deterioration.

Two specifications of material are available for this mount: Yellow for road use (Shore Hardness 70) and Black (Shore Hardness 95) more aimed at trackday/competition use as it is much stiffer.

We recently fitted a yellow mount insert to an Astra H VXR which had covered just over 46,000 miles and the factory mount was already showing signs of weakening due to splitting which if left would ultimately deteriorate fully and  fail completely.

Once fitted there was no noticeable increase in NVH (Noise, Vibration, Harshness) into the vehicle. The vehicle used also had an uprated front engine mount insert fitted. Additionally it was noted that the gearchange had improved and became smoother due to the reduction in gearbox movement at gearchange, due to the uprated gearbox mount insert.

On vehicles with a full set of uprated engine mounts, some minor change in NVH may be experienced by fitting this additional mount.

Rear Braided Brake Hose Fitting – Astra G/H and Zafira A/B

The factory/OE rear brake hose on these cars is a single piece with a rubber brake hose at each end and a solid metal joiner pipe which cannot be reused due to the way the rubber hoses are fitted into the metal pipe.

Our braided rear brake hose kit comes complete with 4 braided hoses (2 for each side) and 2 copper joiner hoses (again one for each side). Unlike some other supplied brake hose kits we do supply the copper joiner pipes with male unions pre-fitted, to make fitting braided rear brake hoses a much more straightforward job.

Additionally the brackets that are used on the factory rear brake hoses can be re-used with our rear brake lines, as this is often queried by people.  We’ve uploaded a few fitting images to show you how its done.
