Hey Guys I just bought my 2005 ram QCSB 4.7L 4x4. I am going to order dual out the rearflowmasters for it with 2.5in pipes and 3in tips. The system comes with a 50 series exhuast, but that is not what I want. So I am going to buy an 40 series originalsingle inlet (3in inlet) and dual outlet (2.5in outlets) and put that on instead of the 50 series. I was wondering if that 40 series (3in inlet, 2.5in outlets) is going to fit my stock truck or do i need a different inlet size. Thanks

 

umm...i have a 40 series on my v6, and it's fine. i mean, it fits from the existing muffler-back...but, everything behind my 40 series is of course customized...seeing as stock is one pipe out the side, and what i have is duals out the back.
