Depends if you wanna spend the dough on the brand name aye, Sure I'd get a Fujitsubo/HKS/whatever brand name exhaust, but I don't have the finances to do so.
I spent $450 on a noname 3inch catback & hot dog resonator from Midas at Penrith in NSW. They mandrel bent the piping & painted the piping & muffler in matt black, I chose an oval exhaust tip as it suited the cut-out section in my rearbar.
It does it's job, sounds aggressive without being noticeably loud that the cops pull me over & I'm happy with it.
