Forget Imco flowmaster magnaflow true duals is the route but around how about how much do you think it'd cost to take my truck to a shop say cut off the factory muffler and piping and run 2.5 inch piping straight from the cats and put 3 inch tips on there

 

I paid $230 bucks at a muffler shop for that same set up, but make sure you have them put in a balancing pipe(h or x) so you don't lose the low end torque, I didn't and I'm going back to have them put it in

 

Even on the 05?

 

the year shouldn't make the cost go up, it's the diameter of the pipe and how much they use, but also the area it may be more expensive where your at or it could also be cheaper.
