Well,jut as the title says, whatis the difference in the two? I had a 12" glasspack on the truck forawhile, and didnt like it, so I ran straight pipe, way to loud for having 2 kids in the truck. Will the dynomax bullet be a better muffler? I am running a y-pipe after the muffler and dal pipes exiting in front of the back tires. Will this work? Will it have the aggresive sound I am looking or? Any help is greatley appreciated.

 

I got the Dynomax Bullet on my truck, 2002 f150 with the 4.6 and i love the sound,

I put the glasspack on my buddies chevy that had a 4.3 V6 and it sounded ok, but when we changed it over to a 383 stroker, it didnt sound, great, it was really crackly and sounded real bad, nothing like a truck should sound.
