        Hi Bob, glad to assist you! This muffler is an exact fit for your 1999 Chevrolet S10. The turbo-style configuration provides great interior and exterior sound control without decreasing exhaust flow. This muffler gives you the OEM exhaust sound that you have been looking for.

    • Q:

      I have a 2000 S10 2.2L truck and need to replace everything behind the catalytic convertor -- is this a bolt in replacement for the intermediate pipe, muffler, and tail pipe? If not, what other parts do I need?
