Check out JBA. I think they're a little louder than the GT500s with a similar tone and price point, and the tips/mufflers themselves look way better
Have you tried the stock mufflers? I run them and have no cats.
LOL, I thought I was the only person on svtperformance with that setup.
I ran longtubes, catted x, borla OTA, and stock mufflers. Put them on because the roush mufflers were too raspy. Stock mufflers were really quiet so we got the gt500's. Then heard a car on youtube with the magnaflow catback and it had a better tone and just a whole better exhaust note IMO. Got that and haven't looked back.
Maybe you should try the magnaflow competition catback?

video doesn't really do it justice.
Funny the different replies you will get. It's all a matter of personal opinion and preference really. I go to work at 7am in a quiet neighborhood and nobody has ever complained about my gt500s ORX and resonator deletes but it's way raspier cold than warm. I just ease out plus I have an auto so I don't have to rev it to get going. I love my set up. No annoying drone at 80 but you can hear it. At 65 you barely hear it. When you want it is there but nothing crazy at all but IMO sound super mean (gurgly/race carish) under WOT and next to dividing walls. That's the best. Pypes ORX. No resonators and gt500s
I love that engine lugging sound of mine right at 2k RPMs. And no way I would add resonators back to mine. And fwiw to who's reading I wish mine was a little louder even w the res deletes. To each their own
