thinking about changing exhaust

[ProStreet83C10]

hey guys, im getting kinda tired of my old glasspack set up on my 83 C10, so im looking for something louder and more aggressive sounding. Ill be the first to say i dont know a lot about exhaust, but so far, this is what im looking into, im wanting a full 3" exhaust, true dual, with an X or H pipe. The "mufflers" im looking into are a full race muffler, with minimal sound dampening from open headers. Heres what im looking into:

Flowmaster Outlaw Race Muffler - 3"I/O, 7"L

DynaTech Split Flow Race Muffler - 3"I/O, 6"L or 14"L (confused between oval or round)

Dynomax Bullet Race Muffler - 3"I/O, 16.5"L

If anyone knows of any other race mufflers with minimal muffling please let me know, like i said i dont know MUCH about exhaust. I want that ALMOST open header sound and volume

Dont forget this exhaust will also be used in conjunction with my 496 BBC stroker with 600+hp in the future once i get it built.



Tell me if any of you guys run/use these mufflers, how you like them and any pros/cons of them. Ive youtubed them and the sound clips all seem the same. I really need to hear them in person.
