I had this made to allow me to pass the IVA test. took a honda type-r engine down to 97db.

its in stainless steel but has discoloured with heat. a quick polish and it will be fine. 2.5" bore. it is full of baffles and wadding.

 

Just fits in the boot. obviously it might not fit everyones but its a good start.

 

£80 pick up in person, Wetherby Leeds or York.

Out of interest what manifold does it fit? Do you photos of it mounted in position?

it was a standard manifold from zcars, but they are all custom made so who knows. It will no doubt need to be customised to your needs.

Holy Moly, that is one gurt big exhaust silencer.....I take it is an absorption silencer (straight through with perforated tube up the middle)?

its not a straight through one, it is a perforated tube next to another one, at the end of the first is a deflection plate. the lot then wrapped in wadding. it was such a pain to get the noise down for the IVA this was the only way we managed it. Im guessing flow isnt great but its quiet.
