I will upload a couple of catless videos later. Nothing catless and no mufflers but you will get an idea.

Where are the videos?!
I've been looking into this for a while. Right now, I got cat-back straight pipes. No resonators, no mufflers. Sounds very nice with lots of burbling and popping but NO FLAMES! LOL I'm looking into removing the cats for some backfire flames, any input on this? I know I sound stupid, but yeah...

I have stock headers and resonator. I then have no cats (straight through pipes) and an AC Schnitzer rear section. I did notice that the sound was a bit louder when I took the cats out, but not massively so. My car isn't really loud on motorway cruise at all; only when you put your foot down. It doesn't drone. I could get a vid of it running if your interested; maybe a driveby if I find someone to give me a hand! lol.

I'm not sure about flames but the popping noises are very quiet; I can kind of feel them getting dissipated in the resonator. My guess is that you would need to take the resonator out if you want to release the pops and flames!

Someone post a video, I want to hear this.

OE headers + Cat Delete + Resonators + Muffler Delete....sounds like a winning combination.

Yeah, I already have the huge popping and burbling, but my cat is keeping me from shooting flames. I'm waiting for someone to upload a video of head-back straight pipes, everything deleted.

If it's sick, I'll get rid of my cats ASAP! but I hope deleting them won't make the car undriveable loud.
If too loud, maybe a small muffler.
