To loud = to old?? Hmmm I must be too old. Then again after this weekend at Martinsville (NASCAR RACE) I can't hear much anyhow.
But remember there is a difference between too loud and just plain obnoxious.
My truck is a daily driver so the sound, not the decible level is what is important. Now my GTX - that is loud and it sounds good! - But then again I don't use it as my daily driver.
Now what were we talking about - oh yea - mufflers!
Just make sure the muffler you get is not necked down inside to fit the larger pipe. Some of the part houses sell 3,4 and 5" mufflers, but the pipe size inside the muffler is only 2 1/2 - 3".
