Okay so, last few weeks been doing a heap of research into what mufflers to get my VE Omega Sportswagon and I wanted to get pretty much the same thing. Went to DEA Performance and they have their own brand mufflers. After some convo with a couple of the guys, they said most of the time anyone with a V6 came back to them to get a catback as the sports mufflers were too loud.
Took it my mechanics for some advise and came to the conclusion of removing the stock muffler all together and see what it sounded like inside/out and diff speeds to see how loud it would be. Only thing I found was that it was rather loud inside in a wagon but that's because the exhaust pipes were pointing outwards into the wheel arches with no muffler. Getting straight custom made muffler put on with tips on Tues so I'm hoping it'll sound good! Will try take some vids.
Not sure how it would sound on a ute. I'd recommend going in and speaking to them and see what you think.
