On a Chevy truck (5.3L, 4speed Auto, 2WD)... what would be the best low tone or stock sounding muffler that still performs better than stock?

The guy I got the truck from put a so-called "stock sounding turbo muffler" and it's not extremely loud but it's still louder than stock.

Is there such a thing as a stock sounding muffler that flows well with less restriction than stock?

I was looking at the Walker 21577 Quiet-Flow Stainless Steel Muffler... think that would be a good one to consider? Are there any better mufflers to be looking at?

 

This should be pretty tame in your truck
5 x 11 OVAL 12579

 

I think it has Magnflo on it now... I wanted it do be quiet like stock

 

2010-14 oem mufflers flow pretty good and are not loud, can be bought used really cheap, if local.

 

That's what the Walker 21577 Quiet-Flow Stainless Steel Muffler is supposed to be.

I guess the only way of finding out if it's what I want is to have it installed...
