Having installed a set of Dave Brookes' sidepipes and headers earlier this year, my previous Dax ones are now surplus to requirements. They were fitted new in 2006, and replaced in 2016, so they've completed ten years service and about 20k miles.
They have no dents, but they have the surface marks/stains you'd expect from ten years' use. However, as they're stainless steel they should polish up well. I replaced the original 3" perforated tubes a few years ago - basically the "cones" at the front end were pretty awful, so the replacements have a longer/smoother 4" to 3" reducer for improved gas flow and cylinder scavenging. Rather than the standard exhaust wadding they are packed with Acousta-Fil, which gives improved noise reduction and reduces the surface temperature.
The headers are for a small block chevy - in my case a 350 stroked to 383 cu in. I'd prefer to sell the pipes and headers as a set, but I might consider splitting.
Due to their size and weight, these will need to be collected from Didcot in Oxfordshire, but for the asking price I could deliver within a 75 mile radius.
If interested, please drop me a PM. In due course I'll be putting them up on the UK Cobra Club forum and on eBay - but this makes a useful first post on this currently empty new board!
