Stock manifold, 300 cell metal cats, no secondary cats, stock midpipe, corsa sport axleback = fantastic!
Won't go into all the details of this journey, but in case this can help someone out since there is very little out there in the googleverse here is what I've found imo anyways by trying all of these combos (All combos are with stock manifolds, stock midpipe)
All stock, corsa sport axleback - great sound, quiet for most part, wot sounds great and not obnoxious. When I had this liked the tone but could have used a bit more volume.
All stock, corsa extreme - got rear-ended and collision center put on extremes by mistake. Great sound, louder, wot was more raspy which I didn't love, and not obnoxious to me, but I'm sure some folks would think so. So I guess closer to borderline obnoxious at wot.
No cats(all), extreme - Clogged cat and removal (all of them) That was ridiculous. It was obnoxious as hell and super raspy
No cats(all), 12" resonators, extreme - went to custom exhaust shop and they put on resonators to stop the madness. Did nice job actually to bring it down and at cruise quiet like stock and extremes, but wot was still way too raspy and obnoxious still with a good amount of throttle. Was also just a hint of drone at normal drone range. The big problem for me was the shop put in 2.5" crush steel pipe! Won't get into that mess, but next up...
300 cell metal cats, extreme - Back to proper size, mandrel pipes. Still too raspy and louder than I like and at wot it was into obnoxious territory. Cruising around, wasnt bad but was definitely louder than stock and extremes. My main issue with this setup is the raspiness is there through most of the rpms. The rasp is less than without cats though.
300 cell cats, sport - part of my enjoyment with cars is how they sound and had to get it perfect for how I like it. So ordered just the sport mufflers without needing to purchase whole new system. Yes you can do that, just need to call them. The car sound perfect now! Volume level in between sport and extreme with all else stock. No rasp just like when stock with sport.
Hope this can help anyone before going on their own very unenjoyable, expensive quest.
