Best exhaust

[mtmckiddy]

What would be the best exhaust to install for fuel economy using factory turbo and not to noisy. 99 7.3 liter.

I like my MBRP 4" with muffler. Sounds nice.

I also have a MBRP 4" turbo back kit.

No matter what exhaust you will go with, dont expect a mileage difference between any of them.

MBRP has a great reputation. They sound good, install as easy as can be, and they wel the hangers to the pipes instead of giving you the clamp-hangers that some other brands have.

I have a 4" MBRP system with a Flowmaster Hush Power Diesel muffler and I love it.

You can go to the summit online and they have tech people to help, you tell them what your looking for and they will give you recommendations. I went with the Diamond Eye ss 4" turbo back with muffler, its not much louder than stock. Gives more hp & mpg.

Magnaflow is the best. Just because i happen to have it though.

To a certain point a pipe is a pipe.

^I hate magnaflow on diesels. Too restrictive.

You previously stated that you dont believe in mufflers on a diesel anyways.

But what part of the magnaflow muffler (which is straight through) is too restrictive?

Your right.. I think mufflers on diesels are pointless anyhow, being that the turbo does a great job of muffling the noise.
