Don't lose hope, Dundon and RK have partnered to bring back the Dundon headers and exhaust, with an RSR style muffler, not exactly like what UR20V posted but similar in function. Proven gains with the header/muffler combo.
For those who want to keep side mufflers, OP has a great solution, fabrication looks great as well...

Yup, Charles and I decided to work on bringing his designs to those not lucky enough to be local. We are crazy for sure. Bring your truck up here, I'm sure we can knock something together.

i made an exhaust that reduces power and sound (dare to be different, power is over rated ;-), but you will pass LS

I'll have my engineer do some screen shots of simulation for you lads.
As for 2:1. I'm not the best at math but we do take a look at this stuff.

That headers / exhaust system was made by Precision Chassis Works.

Believe they're in Arizona. That system was a "one-off" for a customer.
I spoke to them over a year ago. They seemed to have little interest in making another.
Those are Burns mufflers on either side.
Personally I'd get M&M headers and have the rest made by a good local shop.

Ranger got it straight off the bat! I contacted Precision Chassis and after many prompting emails they said the would make one but needed the car - bit of a drive from Australia lol Think it would have been the nuts but no go for me. If someone wants to donate a mule car we could get a few made up

Does that mean yours will be from the cats back, because the oem cats are built into the oem header, right? The system Charles and I decided on was long tube headers, no cats, 2 stage burns mufflers. Made from thin-wall 321 stainless. He said it would weigh 30 lbs or less. So you get most of the benefits of inconel w/o the insane price tag.

Yes cat back.
Catless is great for power gains + track use.
