Yeah you have the two cats and then straight pipes to the mufflers with a bunch of bends on the way. The only way to get more sound is by changing the mufflers out and removing the cats. I don't look at a cut and weld as a hack job unless your muffler shop is a hack shop. There are welders that can cut/weld, grind/polish and make it look like the pipes were never cut, but they cost more.
