Hey guys just purchased my 2011 Dodge ram 1500 5.7 three days ago. First mod i have to do besides the head lights is the exhaust. Im thinkin about doin tru duals cuttin the exhaust at the y pipe and runing 2 flowmaster 40s, on 2.5 pipe all the way to the back and remounting the stock tips on the end. What i wanna ask u guys is will i benifit from tru duals over a single flowmaster setup in any way at all. sound, power, gas mpg, warrenty, etc etc.......

 

I've never been able to compare, but my 09 I had, I just put a flowmaster 40 in place of the muffler, and it slit off to the the factory duals. It sounded great!!

 

anyone else wanna chime in

 

I put on a mufflex retro muffler, it is a Magnaflow 14" with stainless extensions already welded on for an exact replacement fit to the factory muffler. The factory Y pipe on my 09 was a really crimped design so I got a Magnaflow Y pipe and some stainless ex tensions. Cost was $230 for the muffler, $25 for the y pipe and three stainless pieces, mandrel bent for the angle ones at about $35 each and $110 for labor. Total cost a bit under $500. Lots of room under there for true duals, just givin you a price for comparison.
