Keep the stock one, it will flow enough for any mods you'll throw at it, last forever (stainless) and be quiet. If you want some snort out of it then just screw a zerk fitting into the muffler, pump it up with a half tube of grease and take it for a long drive, the grease will catch fire and break down the fiberglass

 

now that's redneck...... i love it!

 

 

Unlike many here, I cannot recommend the Magnaflow 22". There's no noticeable difference in power compared to stock, and it drones bad on the highway. I also think it sounds like ****. I would gladly let someone have my 22" muffler for free if they welded their stocker back in my catback. Worst mod I've done so far.

 

I agree, LTs and no cats makes the 22" magnaflow shine, but most still drone... and on a stock truck I don't care for it.

 

I have a 34" magnaflow, the 13740 I think. Biggest muffler I could find. sounds stockish with *****.

 

I've ran it in all configurations: LTs w/ no cats, LTs w/ cats, and stock. It sucks in all the setups.

 

I'm running a gibson and I am happy with it, it is a little louder than stock and has a deeper note, it is noticeable but not annoying.

 

Out of all the setups I have ran, the quietest next to stock was hearthrob. It was a poor fitting catback dual exhaust kit. Barely could hear it, but it did give good power. You could just get the muffler and put it on there because the catback kit fit like crap.
Edit: come to think of it, the quietest was the borla resonated tips I had with the longtubes and no cats with the loudmouth resonator. They toned that thing down to nothing. Try some resonated tips, they do work and wont hurt power.

 

if you find one bigger than mine, let me know
