OK when I got my car it already had aftermarket mufflers on it and I had no idea what they were. Then a couple days ago my friend replaced the stock muffler on his Impala with a Flowmaster 40 series and it sounds pretty similar to my car. My mufflers don't have any markings on them at all, anywhere. I took a picture of the inside of the muffler through the tailpipe (lol) and it doesn't look like the inside of the Flowmaster 40...

Flowmaster

My muffler

 

I have no clue what kind of muffler that is. But it's a BA picture! How did you manage to take it?

 

Haha thanks I literally just took a flashlight and shined it down my tailpipe and pointed my camera down the tailpipe and snapped it.

 

That looks like a Mufflerman aftermarket Turbo...

Look at the welded on mounts....

Definately a Turbo !!!

 

I think you may be right. This picture resembles what my picture shows.
