Has any body removed the exhaust on thier new 07 dodge diesels?

Answer 1

Should have a 4 inch turbo back, but if you want more are flow to reduce EGT's, than remove the stock cat (litter box) for a high flow Aero Performance 4040XL Cat and remove the stock muffler and add a free flow muffler like Diamond eye mufflers. Or if you are wanting a nice chrome dual exhaust system go with MBRP 4 inch turbo back.

However, if you go with a larger exhaust system like 5 inches you will lose torque in the low end....but you will gain power in the high end.

Answer 2

Warranty will have issues it has a 4" dosen't need any larger. If you want more noise then go with a cat back?
