Nipper exhaust required

[G-ARBG]

Wanted, information, drawings or patterns for original aft facing Nipper MK III exhaust system or alternative proven quiet system. The existing four short downpipe pipe system is proving too noisy for local environment.

Hi David

Don't know if this is of any help but back in the days of the PFA they did a collection of papers called 'Light Aircraft Noise Reduction' with a couple of articles on VW exhaust systems. One of the articles is the acro advanced exhaust system. Could send you a copy of the VW part.
