I was comparing prices on what I need from different vendors. I need 5 bolt stainless steel split downpipes. I also need stainless steel testpipes that go from 3" to 2.5", with wideband O2 bungs on each pipe. Resonators would be nice, but are not required. I was probably wrong to assume that the Alloy Toyz pipes come with resonators, but they definitely come with wideband ports and they're definitely stainless steel. I can get DPs and TPs together for $800, whereas from Specialty Z, similar parts cost $995.
