Need info on free flowing, straight through design mufflers

I am putting tailpipes back on my car and removing dumps. I find this a good opportunity to change my mufflers. I am now running regular mac mufflers. I am looking for a muffler that is very raspy and will give me the most hp gain..thanks for info..
 
what midpipe do you have?

If you want rasy I would think spintechs are the raspiest muffler I ahve ever heard. I would think spintechs with an off road x pipe would the raspiest setup postible.

manapack and lound mouth sound more like strait pipe. strait pipe is not really raspy.

my favorite muffler is the borla xr-1 series. they just sound sick IMO.

MagnaFlows are straight-through, which you can't beat for performance gain

ya. Magnaflow. u won't be sorry.

By the way, i've heard that Str8 through muffler is more prone to raspy sound, especialy with X-pipe. Not otherway around
 
the loudest mustang i know of with a full exhaust is a 03 mach with bbk lt's, bbk o/r x-pipe and the borla stingers. its loud, raspy, and yet very intimidating and aggressive sounding.
