Magnaflow is definitely the way to go. I just swapped from flowmaster and the difference is night and day! Interior noise almost completely gone.

 

After doing a little research, I have heard nothing but good things about magnaflow. I think i'm gonna get the 5" x 8" Oval Center/Center Stainless 18" body/24" overall
instead of the 5x11 mentioned above, just too see how it sounds and performs. The smaller the more agressive the sound right?
Is there much of a performance lost going to the smaller muffler?

 

No performance loss, they all are straight open. It will just be louder the smaller muffler you use. I believe you will want 3" inlet and outlet as well.

 

Hooker Aero Chambers! 'nuff said ...

 

What size muffler(s) do you have?

 

You will need a three inch to just splice it into your exhaust cause factory exhaust is 2.75"

 

if you are interested in a magnaflow I have a friend who works there and I get awsome prices, he is not a sponsor so shoot me a pm and I can tell ya.
