I'm running catless Gintani x-pipe. It's pretty damn loud! Sounds AMAZING... hate to give it up...
Also, the neighbors in MY gated community actually do not care. Many of them say it sounds so good they don't mind.
It's the neighborhood across from my gated community that hates it. They say when I drive up my hill (exhaust is pointed directly at their neighborhood) they say the sound ricochets throughout all the homes down there and shakes the windows and walls of their homes making their dogs bark and waking them up.
