All,

I was in a minor car accident and had my muffler and muffler gasket replaced on my FX35. My car was really quiet before, but now there is a much more pronounced growl when I start and when I accelerate. I am wondering if this is normal after the muffler is replaced (like if it takes time for it to work in), or if the people did a bad job and now the car is worse that it was before. Any advice is appreciated. Thank you so much.

If it's a different muffler, than it's going to make a different sound...
