A friend of mine was thinking of installing a performance exhaust on his 98.5 cummins dodge. I suggested straight piping it with a 3" or 4" exhaust system. He said he had heard that straight piping it was somehow bad on the engine. I can't see how this could be a problem with a turbocharger. If there is something I am missing here, please advise. Thanks Mike
