Are Pypes catted X-pipes any good, they are $250 compared to double that for Magnaflow of Bassani catted X pipes. I want to buy catted X pipes for my 98 cobra (2 chamber flowmaster 40's) and 03 Cobra (Magnaflow CB). My choices are Bassani, Bassani BX (aluminized), Magnaflow, or Pypes. Pypes is the only CARB certified catted X, so that is a plus to me. 1. Are most Bassani guys running the stainless (more $) or aluminized (BX) versions? 2. Is the Pypes X any good? Any 4V guys running it? 3. Any problems with blowing cats on the aftermarket X pipes?
