I've always had good luck and quality with flowmaster, and have always been able to get the sound I want by knowing the ins and outs of the different series. The series 40 dual chamber would be way too much and would drone like crazy on the highway, especially if put in the stock muffler locations in the back. But the series 50 3 chamber delta flow would sound a lot smoother, and placed in the middle vs rear shouldn't drone much if at all.
And the E53 4.6is and 4.8is tips are the same, but the mufflers themselves are slightly different. Still interchangeable though.
If I can find the 4.6is style rolled edge rectangular tips I'll go with that, otherwise some rolled edge dual round tips will look good enough.
And of course I have no idea when I'm gonna have the extra time or money for this project as I currently have to pay back family, pay a couple grand in medical bills from the surgery, save for an $850 kayak, buy a couple replacement parts for my 3-wheeler, buy steel stock to modify my trailer, get polyurethane thrust arm bushings for my truck, etc. etc. etc. Too many projects, not enough time or money! (can I get a grant for the make weasels life easier foundation?
