Hey guys,

I'm really not a fan of loud exhausts and I like to get mine as quiet as possible. Currently, I have stock exhaust manifold --> test pipe --> resonator --> OBX twin loop muffler. This is on my Civic Si, so it gets pretty annoying at highway speeds (~4k rpm).

I'm not trying to spend money on a completely new setup, so I was thinking of adding another resonator. Either that, or replace the muffler for a quieter one. I've read that the Apexi WS2 is super quiet, but it comes with a pretty hefty price tag versus $100 for another resonator.

My understanding is that a resonator will tone down the noise considerably more than swapping the muffler. Do you guys agree with this or should I look into replacing the muffler?

Just adding a resonator should help reduce the noise. Getting a quieter muffler will help also.

Vibrant are pretty quiet. Magnaflow too.

Thanks for the reply. This next question sounds pretty dumb, but does the Si stock exhaust system come with a resonator? I looked up the diagram and it's listed as "Pipe B" without explicitly stating that it has a resonator.

I know the stock Si exhaust has a resonator. Others removed it for a louder exhaust system.
