Exhaust System

[Standman]

Hey Guys. I’m looking to buy an exhaust for my 03 F250 6.0 4x4. I’ve been reading a little and figure 4” and a quit sound is for me. I need some help with definitions and a good Muffler.

What is the best sounding/performance Muffler?

Is “CAT BACK” just from the Catalytic Converter to the rear?

Is “CAT DELET” from the Turbo to the rear, Or just an extra tube to delete the Catalytic Converter if you want?

I figured “TURBO BACK” is a complete system.

Thanks

If your after 4" with quiet sound I would recommend leaving the cat in place and just do a Cat-back system. All the 4" systems have a straight through muffler so you really won't notice a difference between any of the brands. I would recommend either a MBRP or Flo-Pro System they can found on my website or just call for even better pricing!!! Lemme know if you have anymore questions.
