While crawling around under the crewcab today I noticed the muffler has a few little holes in it so it looks like it time to replace it. I want a QUIET muff, no frat daddy flowmaster 40's. I need a 2 in 1 out version and I believe the pipe sizes are 3" in and 3.5" out. The motor is a vortec 454.

Here are a few that I have come up with so far.

Dynomax and Gibson's websites both suck and I couldnt find anything that would fit my application but if yall have any recomendations I'm all ears.
