Another new product to hit the market is the Nur-Spec C-Ti exhaust, from Blitz Power
Unfortunately the details on this exhaust are even sketchier than the A'pexi catbacks, however the C-Ti comes with full SUS304 stainless steel piping, with dual titanium tips, not unlike the A'pexi RS Evolution. Piping is 60-70mm in diameter. MSRP and ETA for US delivery are not available currently.
