Take what alot of people say on here with a grain of salt.

On our Honda's, ANY Canon style muffler (regardless of brand) with a single resonator, no matter how big the resonator is, will be ****en loud. Obviously loud is a logarithmic term, but from your post you seem to want what I wanted a 6 months ago so I can only comment from experienced, as opposed to many here who can only comment from no-experience, no-knowledge, brand whoring and the unequivocal transvercent use of the acronym JDM.

I went with a 2.25" inlet 4.5" outlet canon with a single large (very large actually) resonator. It sounds really, really good. BUT it is overwhelming loud inside the cabin at 2500-3500rpm. If this is to much for you, the only option you have is Twin-loop with single resonator. Above 4400 though, the car is absolutely mental, which is the reason the catback is still on my car.

You can try running 2 resonators into canon, but even then, when you step on it and the engine is under back pressue and under it's power band, it will still be loud. And from my guess, to loud for you.

In short, large resonator + twin loop is what you want. Save your money on the cat back by going X-Force, and spend big on the headers.
