Exhaust Best Muffler For 2005 V6?

[JakeG]

I recently purchased my first mustang which is a 2005 v6. I was wondering what would be my best option for a deeper/grumbling sound. I know it's only a 4.0 so I'm not expecting much but I want something more than the stock exhaust.
Anything is appreciated!

I have the Magnaflow dual exit exhaust on my 05. I listened to all the clips I could find before I decided and personally it sounds really mean when you rev it but to me from behind it going down the road it sounds like a Ferrari. The Magnaflow was the only glass pack style exhaust on the market for the 4.0 then.
I've had it 11 years and still sounds great. When I take it in for tires they always think it's a GT.
