Here my car on the dyno. has magnaflow catback and BBK o/r x-pipe. My buddy has the same catback on his 03 and it is very quite with the stock H. Mine on the other hand is very loud.

I've got it with the stock midpipe.
It sounds good -- not too loud, but loud enough to get you noticed. Great deep muscle car tone, nice crackle on deceleration or when you rev and release.

Magnaflows do have the classic deep tone to them like everyones stated, and they arent the loudest, but they are definately HEARD. Tho its not the loudest catback but add an x pipe and its'll scream.

I personally have the flow master exhaust, and I love it. Deep throaty sound and not to loud on the inside. My neighbor tells me it is an awsome sound when I roll by his house.

The magnaflow magnapacks are loud, but my friend has a 2002 roush with a magnaflow o/r x pipe and magnaflows and its not very loud. I do like the sound though.
