Yes exactly what I did.
In my opinion 4” down pipe back with muffler is the way to go.
It makes for an easy install perfect fit without clearance issues.
I believe you will be very happy with it, and please keep us posted.
Remember to use the zero switch setting (30HP) when towing that Toy Hauler and I would highly recommend adding the EGT probe to keep an eye on your exhaust temperatures.
