Loudest thing would probably be to remove all 4 cats and put 1 hi-flow cat on each side with all 02 sensors put back in place. Only comment I can make about the sound is that my friend and I both have the same Roush offroad exhaust, he has an 04 and I an 06 (both 5.4s), and mine is louder, but not by much. I couldn't tell the difference until compared side by side

Last Maggie hi flows I had on my 02 got clogged up so that is not an option. I ended up having to run them gutted out and pay 350 for a custom tune on top of the cash spent on the hi flows and installation of them. Got pretty pricey and I want to avoid any chance of that this time around.

Won't the 02 sensors stay where they are? In this case they are between front and rear cat. Or will they have to be moved? I figured the shop could just cut out the rear cats and tie in some new 2.5. But I honestly don't know how this will need to be done

Got the rears cutoff and I am happy with the sound. Its not too loud but has a nice aggressive tone and did get louder than it was with them on. Overall I am happy how it came out and would recommend it to anyone looking for something extra.
They charged me $115 to do it. I figured it wasn't to steep considering most shops won't touch them. Guy was insistent on gutting out the front 2 but I couldn't do it. I told him if for some reason the cel comes on I will go ahead and gut them. Hopefully it doesn't come to that.
I might can get one up in a couple days or at least get a link to YouTube. Not quite sure how to embed videos.

1. Even though you are exempt from inspections, you are not exempt from the requirement to have them- even US Fish & Game Wardens carry a manual that identifies each vehicle and the required smog equipment, illegal engines changes, etc with pics of how to ID.
2. Any law enforcement officer (including fish & game), EPA inspector, etc. can impound the vehicle and cite it as a gross polluter
3. Once cited, a judge will decide if the vehicle is to be scrapped or returned to the owner- and you do not have any opportunity to speak in court- just required to sit & listen.
5. if the vehicle is returned- guess what, now you have to repair and take the vehicle to a federal referee station for the rest of "its life" for a smog inspection & test.

. . . That almost never happens to anyone. And you've got to be a total hoe to report somebody for that. Tons of people runs no cats at all and never get caught. Most cops think it's cool and ask questions haha. If I was in Cali, like you Beechkid, I'd probably would worry about your state's over-the-top liberal pollution crap, but Texans don't care that much haha.
