I'm not looking for performance gains, but I'm one that enjoys the sound of a nice exhaust note. I have a GS400 with the mufflers removed. I like the sound, but I could want it just a little louder. My question is, which resonator does more sound suppression, the long glass-pack shaped resonators or the oval resonator before the exhaust splits?

The oval one before the exhaust splits is actually the third cat. The one that muffles the most sound is the long tube/glass pack shaped resonators.

Thanks Jeff. I really didn't think it was a cat at all. I don't expect to, but will I get a CEL removing it?

Actually, it is a cat on the GS430s but it is a resonator on the GS400s.

Do to their placement the resonators will have different effects on sound.

It really is personal preference. I would probably start with removing the two resonators and only if not loud enough then the center.
