I came across a Magnaflow Pro SS 4" kit that I am thinking about getting.
Magnaflow Pro 4" Turbo-Back 99-03 Powerstroke 17979 | Exhaust Systems | 99-03 7.3L Power Stroke | Ford Power Stroke | Diesel Power | Performance Truck Products

It is $317.xx shipped to my door. Before I came across this I was thinking either the MBRP 4" installers ($365) or performance ($300) system.
Riffraff Diesel: MBRP 4" Turbo Back Aluminized
Riffraff Diesel: MBRP 4" Turbo Back Aluminized

Which way would you go?

 

I have the MBRP 5" Aluminized and LOVE it. Also the delete pipe. Only one thing is I would paint the clamps and hangers before I would put it under the truck. They are the only things rusty after 2 years.

 

What he said

 

Just as an FYI, I bought this kit from them:

PTP 4" Turbo Back Budget Kit 99-03 7.3L (T409 SS) | Exhaust Systems | 99-03 7.3L Power Stroke | Ford Power Stroke | Diesel Power | Performance Truck Products

And guess what it is? It is a Magnaflow kit. Came in the same box with the same Magnaflow part # that you posted. And I love it. You can't beat $309 delivered for the SS Magnaflow kit.

 

I have the magnaflow kit on my truck, and the mbrp kit on our early 99. Both 409 SS. The mbrp seems to be more rusted over the axle then my kit does. FWIW

 

Thanks for the info. I just made them an offer of $290 on it so we will see what they have to say.

 

Yeah i love my magnaflow kit. Put the straight pipe in it and sounds great. Very little to no rust in most spots. Very happy with it.
