DEPENDS ON IF YOU WANNA SOUND LIKE A BIG TRUCK & HOW SENSITIVE THE COPS ARE IN YOUR AREA?
I've actually found some great buys at local Muffler Shops where the local PUNKS have bought an Exhaust System for their Dura-Max's & they had the Muffler Shop Straight Pipe it,the Muffler Shops usually keep the Mufflers & sale them reasonably,My last work Truck(Dodge) was sportin an after market Muffler from a Dura-Max Exhaust System,it's Straight Through design did help the Cummins a little,was a little noisier than Stock but not bad!
Don't confuse the Muffler with the Obama Pipe,AKA Particulate/Re-Burner,I've seen many of these Plug up,and if you do decide to put a Chip/Programmer on it you will have to remove the Obama Pipe!
Question is:
You want it to Breathe/Run?
Or not?
You wanna be able to make somebody Inhale at your choice?
Or do you wanna run around in a SMOGGER BELCHER only using a Fraction of what is really there?
Anyway,if you do one thing you'll need to do both,Quit feeding the Exhaust System Raw Fuel for GAWDS Sake,you think that improves Mileage?

It's been a long hard ride
Got a ways to go
But this is still the place
That we all call home
