I have headers with a catless Y pipe. I have ONLY a muffler. It is way to loud for my liking. What would be the best way to make it quite? I don't really want to spend 500 on a catback. I'm looking at removing the magnaflow muffler I have now and putting in a muffler to quite my truck down. What do guys recommend? I want to lose some noise.
*I have a cut-out if I want loud*

I've been thinking about getting the 12288 or 12388 for duals, or 12279 for single. Just dont know how loud it would be with resonator delete and no cats.

I installed the 12259 and it sounds good with everything else stock, little deeper. It's approximate 6" shorter than the stock gigantic piece.

No sound clips but check here and youtube "12259" or "magnaflow 12259" and there's a few. With your headers it may do the trick.

chase I wouldn't get the 16656... that's the entire catback. I'd just pay a fraction of the price and get a big muffler... but I've heard the 16656 is super tame.

Mangnaflow part number 14834. Race muffler with 4 inch tip. It will cut being loud in half, help hide the cam but has a deep throaty growl at WOT. It will go in place of you resanator in back.

performancepeddler.com has them listed for 131.00. They do take a best offer for them. When I got mine I offered 85.00 and they came back with 98.00.
