does any know the diameter of exhaust on the ss. I want to replace the muffler only.If anyone has any suggestions on muffler would be helpful.

 

2 1/2" , Magnaflow

 

You are going to have a hard time finding a better flowing muffler that doesn't make the car sound like a fart factory. The SS muffler is very sophisticated. I would not expect significant gains from a muffler change, and I would be willing to bet that the power / obnoxiousness ratio would be rather small.

 

Thanks for the advice
