Dual exhaust exit Pipe Diameter
Ok so I did do a search and everyones opinion about exhaust manufacturer seems to be different. Thats fine, my question is what diameter pipe did you use/wish you used after the muffler. I plan on putting on a 1 in 2 outexhaust from the cat back. I've read that toolarge of a diameteryou lose your low end. And please don't let this turn into a backpressure/velocity debate.

I went with 2.25 out from behind the muffler. Everyone was saying about low end loss if you go to big, but I notice none. I went with a Flowmaster Delta flow 40 and like the sound. "That is another controversy". I don't know if that muffler will sound good with your 3.9 though. Some like it, some don't.

RE: Dual exhaust exit Pipe Diameter
for the v6 i would go with 2" ID piping to fool many ppl try to keep the truck at a low rpm to makeit seem like its got a v8 my cousins 4.3 v6 sounds like a stock 350 at low idle and up to 1700rpm i havent heard it on a 3.9 though and teh tips also have a roll too big and youll ruin the sound and too little, theres no point, i have a 3.5 rolled edge on mine that are 18" long but it also has a v8 if i were you i would put 12"x 3" diamiter tip with 2" piping from the muffler back mandral bent tubing would be best also
