  1. Just changed out the standard exhaust on my 2010 GT with flowmasters. Question...Do i have to disconect the battery cable so that the computer can adjust for the new exhaust? One company says yes and flowmaster instructions say nothing?

    Sound is beyond awesome. The sound is deep and the best sound I have ever heard out of any street car.
  2. I didn't on my 08. No problems.
  3. It's just mufflers I don't see the need to. I didn't on my 05 and had no problems
  4. No update needed.
