Had to purchase a new exhaust manifold/catalytic converter for my 08 Colorado due to a cracked exhaust manifold. With a new O.E.M priced at over $600 and a Magnaflow just a bit more, of course I chose the proven leader in performance. Along with the Catback system I also installed, I can definately feel a difference. Seems to have more horsepower and quicker throttle response.-
