How does the Race Exhaust sound with a Header? But I've looked on the c-f-m.com website and it say nothing about being carb legal in Cali (whereas the Street one DOES say it's CARB legal)

I'd kinda prefer to go with something louder than the Street Exhaust, but if possible, I'd like to buy a resonator to go with it, so for casual driving the noise doesn't drive me nuts, but for when I want that excessive roar, I can take it out and enjoy the extra vroom.

When driving gently, I can hear it inside the vehicle with the windows up, but just barely. When cruising on the highway @70mph there is more wind noise than exhaust sound, it doesn't drone. You can hear it with the windows down/outside the vehicle just fine, it is louder than stock. To me, any louder would be annoying (I don't want to deal with a droning exhaust on long trips) and I don't want to draw the wrong kind of attention to myself.

I'd take some videos if it weren't so damn cold outside. But ask yourself this: Do you really want an exhaust that screams to law enforcement "Pull me over!"? Do you really want to be one of those guys whose car makes more noise than power?
Yeah, I understand that. That'd be kinda lame to have a car with a ton of bark but little bite. But on the other hand, it would be kinda cool just for the hell of it. But like I said, I'd like to have a loud exhaust with a resonator so I can have the best of both worlds.
