Isn't the Magnaflow muffler you used a Tri-Chamber one?

I thought this would give a more toned down sound, what would the car sound like with a performanca muffler?

I'm scared it would sound too loud.

A couple more questions:

1.- Is your system a cat-back? Did you change any of the plumbing prior to the cats? And if so, what cats did you use?

2.- Isn't a 20" long muffler to long to fit in there?

3.- If it isn't too much to ask, could you take pictures of your car from underneath too see it?

Thanks a lot.
