WTB Single tip mufflers or trade for my twin tips

[kennysti]

I'm looking for a set of single tip mufflers in stainless possibly 4" like the ultrex single tips. I am currently running a prototype set of ultrex 3" twin tips but I think I prefer the singles. Doesn't have to be ultrex mufflers but if they bolt up straight to the stock system location I'll be interested. Preferably someone in Perth? But open to people interstate.
