Wanting to run a straight pipe exhaust on my 2004 6.0L Excursion. Would the MBRP PLM Series 4" Turbo Back Exhaust fit around the rear gas tank, etc.? Thanks for the information
MBRP PLM Series 4" Turbo Back Off Road Single No Muffler Exhaust -
If you currently have the stock exhaust, I'd do a downpipe back or cat back exhaust.
When I got a full 4 inch Flo-Pro system, I lost low end power on my truck stock and tuned (hot too). No matter who's tunes I ran and/or how hot I tuned the FICM (Econo, Atlas 40, Atlas 80) the bottom end spool suffered along with my fuel economy.
After talking to the engineer who wrote the software these trucks run on, he mentioned that unless I plan on racing my 6.0, the best option for spoiling was the stock downpipe and exhaust.
To that end, I bought a diamond eye 3.5 inch downpipe and installed it. As soon as I did, my turbo spooled night and day better and over s few tanks of fuel, my fuel economy recovered nicely. Turns out he was right on the money
There are also fitting issues with the 4 inch down pipe. The stock and even 3.5 inch downpipe fit much better.
Diamond eye does but you'd have to check a few FTE vendors. Exhaust companies make more money on full systems than they do the cat back systems so they tend to push the full systems more than anything else.
Diamond eye also makes a turbo back system with a 3.5 inch downpipe
Bought the Diamond Eye Exhaust. Thanks for the information. It is coming in the mail from Thorough Bred Diesel tomorrow. Will update once it is installed
Final Question. Bought the 4" straight pipe turbo back exhaust from diamond eye. Looking to delete the cat as the system calls for reinstalling the old stock one. Where can I buy a replacement? Because it asks for the stock cat I should be able to get a cat delete for the stock exhaust, correct?

Seeing as you have a diamond eye exhaust, they make a cat delete pipe that goes with their kit. My exhaust ended up as a 3.5 inch until it was past the passenger side front door. From there it's 4 inch back.
If I had my truck, I'd take a picture of it for you, but it's sitting at one of the laziest transmission shops I've ever seen.
I saw that they had that, it doesn't look like it fits for my kit (K4352A-RP) they also sell a cat delete pipe for the stock system and it (my kit) says that it's designed to have the stock cat reinstalled.

yep, get a cat delete pipe and you'll be good...and you'll love the sound of the exhaust now. It's awesome
