I may be a bit slow at times, but I don't understand this.When it comes to exhaust, there are so many options that it usually just comes down to how it sounds over anything else. If you are pushing 500hp or more, you will need a 5" but anything less stick with a 4" turbo-back. I am running Rolling Big Powers 4" turbo back and I love it, but I know guys with MBRP systems and banks systems too that love theirs. Talk to everyone you have locally, listen to their systems and pick the sound. As for fuel economy, they are all going to do about the same.

Where does it say that you need a 5in exhaust for 500hp???
Really now. I'm trying to find this "everyone". Please point me to everyone.Everyone in the diesel exhaust industry will state that a 4" exhaust is great and will work great untill you start pushing 500hp or more. When you get more hp you get higher EGT's and the extra inch helps reduce them...I've heard it over and over again from everyone in the industry
Go stainless and turbo back.Just would like to know if I should go stainless steel or aluminum exhaust? cat back or turbo back? Thank you Jim
I'd like to see a 5in turbo exhaust housing that requires a 5in exhaust.opcorn: Waiting for "everyone" to show up and chime in.
The only way I would buy the 500hp requires 5", is MAYBE if they were bolt on hard parts that made 500hp, that you couldn't detune and you were going to take a car hauler through the mountains in the middle of summer.
