Attention: TDR Forum Junkies 
I have a 51" Donaldson and want to replace my stock muffler but keep the kitty. I'm talking about an 07 5. 9 SWB Quad cab 4 x 4. I've done a lot of searching but my question doesn't show up. What problems will I have with connecting the original tail pipe back up, since the donaldson is a 4" straight in and out, whereas my stock 4" is offset? I've not picked the muffler up yet so I haven't been able to physically match them up to see. I assume I will have to cut about 10" of the pipe to compensate for the difference in length, Donaldson 51", stock 41". Thanks in advance.
