Straight pipe, here also.............no problems, sounds great.........gets lots of dirty looks from people that don't like it, especially older ones

 

I had mine stright piped for several months and it was a bit too loud for me. I live in a court and when I would roll in late at night it would wake up the neihbors.. I also leave at 5:30am wich allot of people do not like being up that early. I replaced it with a MBRP and LOVE LOVE LOVE it. Cool Duals look great from the back of the truck and the sound is perfect. I am running no cat.

When the truck was stock I got 15.1mpg, stright piped 14.2 and now with MBRP 16.1.
