Dynomax catback on 99 5.7?
#2
I think Dynomax make a great performing muffler. I had the "ultraflo welded" 1 in / 2 out on my truck. The only problem I had with it was it had to much resonance for my taste. When the whole family was in the truck, it made is a little difficult to have a conversation at highway speeds (when it was 70mph down here). I also tow 6200#'s at almost 3000 rpm, that was loud for way to long. I just wanted something quieter when I tow.
TX Silverado: it's still yours, I just haven't had time to get back with you to set up a time.

I love DynoMax which is why I've had them on all my trucks. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
It'll definetely be louder than stock, but more heartier. It will not be overbearing in the passenger compartment.
