On C5's there are bolted flanges in the exhaust pipes behind the cats, but in front of the rear axle. If anyone talks about a 'cat back' system for a C5, they are talking about from those flanges back. No cutting/welding at all is required for a cat back muffler replacement. HTH

it is a misnomer. The cats (catalytic converters) are many feet in front of the flanges where the after market "cat backs" attach. It is just a short cut way of say mufflers from the axle back. It is not from the cats back as that would involve some length of exhaust piping from the cats. My guess would be several feet (4).
