I've researched exhaust and it was between the moroso spiralflow & the aeroturbine 3030xl. My truck is an 06 hemi 4x4 RCSB.

I finally got a tuner and turned off the mds, so now it's time for exhaust. I can't find a lot of information, but the moroso spiralflow seems to be really good in the "underground"

I plan to replace the muffler with one spiralflow and run dual's out the sides, then i started to think about flow. I would think the stock muffler is much more restrictive, so i should be fine with 1 3" in 3" out muffler? Any concerns? Any testimonies how this will sound? My appt to have this done is Wednesday morning. Thanks all
