What is a Cat-Back Exhaust?
A cat-back exhaust replaces the exhaust system behind the primary
catalytic converter. A cat-back exhaust usually offers a little less performance
improvement than does a more comprehensive exhaust upgrade, but eliminating the
pipes behind the cat still pays large rewards! A cat-back system also is just as
impressive on the outside as a full exhaust and tells the crowd you mean
business.
