Yeah, it's just too loud for me. I have 2 young kids. And when they are sleeping, I can't even take the car out cause my wife will yell that I'll wake them up.
So if I bought a muffle with a 2.5" in and out, then I can just swap it? I know I'll need an adapter since the pipe coming from the cat is 3". I don't want to replace that entire pipe.

Pulse length of the exhaust, each time it fires you have a low pressure wave behind it, the larger the pipe with the same flow, the shorter the wave, if they space out too far, the pulse behind can't use the tow of the pulse in front. ooo-ooo-ooo might be the spacing on the smaller exhaust, larger, its O---O---O, the big spaces are less efficient. Higher RPM reduces the spaces, so at race RPM it has more flow.
