How are they planning on running the pipes with the side saddle fuel tank? Are they planning on running both pipes down the right side and cross the left pipes behind the axle, or run each side outside the frame rails? Pics. would be nice when the job is completed.

Thx. Not sure how they run the pipes. I will post some pics & video when done. Getting 2.5in piping with 18 x 3.5in rolled tip stainless Magnaflow true duals. Tips will exit angled behind the tires. Anybody have this set up? Just wondering about the drone, hopefully it's very minimle.

You called them "true duels." To me that means a complete duel exhaust system,
independent from each other
from the headers back, just like the good ol' days. Which would obviously require having two Cats, which we didn't have in the good ol' days.
I didn't think it was legal to change anything unless the Cat was defective, but
I'm not an expert on this.
Will this involve any problems with O2 sensors, and how this info from 2 Cats
feeds into the
computer?

I called the shop to clarify. I guess it's not going to be "true duels". It will be a cat back stainless custom bent system with DIDO. Sry for the mix up all. I will post pic & vid Friday or Saturday.

The sound is frtricken awesome!!! Start-up has a low growl then a low key rumble at take off. Highway 75-80mph no drone at all. In town 30-45mph low growl until the go peddle is hit.... then it will turn some heads. Very very happy how it turned out.

Just one problem with that exhaust. The truck is now illegal to run on the street and can be impounded with out cats. It's a federal dot emissions law. I would NOT recommend doing this on a daily driver.

And can you show me and others where it says it can't be driven? Specifically to the acutal law on the books, federal or state??
BTW, sweet truck.

The truck was built to get the most gains as possible and since I don't live in California or a state that requires a emission test I decided to take my chances especially when Mustangs, Camaro's, and many other cars that have been modded are running off-road x or h pipes frequently.
