why did you buy it? most people do a little research on their exhausts, but ive only seen the silencer for a few ones. I wish i could help you, my first muffler started to rattle, crappy weld, couldnt getmy money back so i went with magnaflow, it's VERY quiet in the car and sounds mellow yet attention getting from outside. SCC tested it in the last issue, and claims it produced the most power out of a few different mufflers. I dont work for magnaflow or anything, lol, im just proud of it! I guess, Im a loser. But ya, i dont think those have a silencer available.
yeah im getting a resonator put on tomorrow can see how much that helps...if it still doesnt help all that much i'll send the muffler to thermal and get them to put the stealth version on it which they said will decrease 5 dB for free
