I'm running borla stingers on my 03 cobra, best sounding exhaust IMO, no drone, not terribly loud until you get on throttle then it sounds really agressive

 

I went with the magnaflows - not bad, not loud enough for me but nice. I wish I went with the magnapacs as they are louder. However the tech at magnaflow told me that the magnaflows break in after 3000k so we will see how they sound in a few months.

 

gfong has SLP on his '03 Mach 1,mid pipe,and cat back,and it's loud!!

 

my neighbours 03 GT has Loudmouths on.... they're damn loud and you can feel the house shaking too from the sound.... I had the privelage to have him rev the crap out of the car in a garage and the echo was ear piercing enough....

definitely loud and aggressive sounding
