There are two suppliers of mufflers in South Aust but only one who makes pipes as well that I know of. His name is Ric Paull and has a business called Reband, phone no 08 85645122. I have bought pipes and mufflers from him and they are good. The other place is called Redline exhausts in Adelaide, the mufflers on my A10 are from him. I dont think he does pipes but it would be worth ringing him to find out. His name is Terry Merritt and his phone no is 08 82770311. Hope this helps.
