Frequently Asked Questions

  • How do I know my muffler is bad?

    There are several signs of a bad muffler: 1) Your car may backfire due to corrosion. 2) Your car may delay when trying to accelerate while driving. 3) Your vehicle may not pass smog or release an abnormal amount of smoke. 4) People hear a rattling sound from underneath your vehicle.

  • Why should I upgrade my exhaust, muffler, or tip?

    It comes to preference when selecting the right exhaust system for your vehicle. Some people want a louder “Throatier” sound while others want a better look and of course performance. We are able to sample the sound your car will make prior to your purchase and installation.
