Well as you say, the vans and pick-ups had these dampers fitted and were fine so I don't really see what the problem is.

HAHAHAHA

anyway, the topic isn't dampers, it's silly exhausts that will weigh too much and cost too much.

anybody know a company that does a range of silencers? space is limited at the back with the distance between the axle and the back of the car, and with the space either side of the petrol tank, so silencer selection will be key.

Have you thought about a Cherry Bomb here...http://shop1.actinicexpress.co.uk/shops ... dc98ef3667

Universal silencers etc...http://www.demon-tweeks.co.uk/Performance/Exhausts/790

cheers for the links ratrod, will get my tape measure out when i can

Love it!

Walker Dynomax do a very good range of silencers plus very importantly they quote flow figures so if you follow Vizard you can spec a silencer that will not impede flow. However availability in the Uk is not good. Jetex also do silencers.

DAMPERS:

Dampers work by passing oil through valves. The more oil you pass the more "better" the control. Therefore the damper should move as much as possible and be as big a possible (big piston) Therefore you need to translate as much wheel movement as possible into damper movement. Racing cars run linkages to increase the movement. On road cars upright dampers will achieve this.

The angled dampers on the commercials is driven by packaging and is a performance compromise. Plus angled dampers will have a falling rate which is not ideal either.

Jetex silencers are superb. When I made up an exhaust for an old Beemer I had one of their mid silencer it damped out the noise and reverberation of two cheap stainless items that came with the car. It was also totally straight through.

What is the aim of the exhaust? Why not run one large oval silencer before the crossmember and exit in front of the rear wheel? This will require potentially only one bend! It works as well, this is the system I have on my car. It has a nice burbly note but it doesn't drone and it isn't noisy at all. Moggies are noisy enoug as they are!

Surely if this relates to your course you want to make an exhaust that is as effective and lightweight as possible? You don't want to use a deep silencer as this can limit the minimum ground clearance.
