Mine is rusting thru.

I think I will go with stainless.

Any recommendations on a good one? What about adding the banks power elbow? Anyone with experience using it?

I'm looking for more power, more mpg, and cooler sound...basically everything...if it exists.

 

I have MBRP system, Aluminized steel. 10 years no rust.

Everything fit just fine, sounds great, reasonably easy install as I recall. (I did unbolt the transmission cross member). ...so no complaints.

 

10 years with no rust is pretty good.

 

Banks is over priced and the difference is negligible, if any that a 7.3 would ever notice.

I went with Walker 4" steel pipe and the Walker big truck muffler, love it, no drone in the cabin now

here in OkieLand, exhausts don't rust

 

I bought that Diamond Eye 4" exhaust kit last year for $400 shipped when it was on sale at ebay. Yeah it fits but a lot of screwing around to make it work. My Ex had 5" exhaust on it with a huge 4' long muffler that was rusted out so I removed all that. The straight pipe was loud so installed a Walker resonator...I should have just bought a Hypermax 4" exhaust kit with resonator to begin with.

 

Yes, same in my case. It is in good condition.
