    malo que va del silenciador o del convertidor catalítico

  • Sounds like exhaust problems from hole in muffler to broken flange at the catalytic convertor.

    The exhaust system for leaks inspect the catalytic converter and replace them if necessary.

    sounds like hole in pipes, but also check to see if it has a sparkplug not sparking or a hole in one of the pistons.

    Sounds like a exhaust leak. check the manifolds & e.g.r valve gasket. The catylitic converter & muffler have to be in bad shape to sound like that.Visit your local muffler shop & ask them to perform a back pressure test to rule out catylitic converter.

    Obtenga su escape fijo. Si encuentra un buen silenciador tienda, va a costar alrededor de 100-150 dólares.
