I have a flowmaster 40 series on my truck right now. It sounds great, but since I got my TT3000 it gets on my nerves on the freeway, and the droning puts me to sleep.

I need help picking out a quiet muffler and a electric cutout. I'm looking for a near stock sound without the restriction.

Does anyone have experience with the large case (22" or 30") magnaflows?

 

I talked with a guy who owns a chain of muffler shops in Oregon who said the absolute quietest setup you can do is this 22" muffler (#14588) with the 2.5" outlets going in 2.25" dual pipes:



I'm doing the muffler above with this other muffler (#14219) in front of it, just because I hate noise, but need the flow:

 

Wouldn't the 30" muffler be quieter than the 22"? And does the dual-out flow better than the straight thru? I'm just gonna dump it, I think tailpipes look tacky.

 

I would do a longer boddied straight through muffler. Magnaflow will be your best bet. Great quality, and if quiet is what you are looking for that is it.
