Best exhaust for Mustang GT

When it comes to car repair and maintenance, most of us overlook the exhaust. The fact remains, though, that it is of paramount importance because it gets rid of the harmful fumes.

That’s not all, a below par exhaust system will reduce fuel economy and increase emissions.

  • Check engine light is ON
  • You hear rattling noises
  • Fuel efficiency has taken a hit
