APEXi N1 Super Silencer

[dayna240sx]

Ok, I'm moving back home in about 2 weeks. I have an APEXi N1 dual exhaust, hotshot header, and no cat on my car... So it's loud as hell. My parents are bitching about it being too loud because they live in a yuppie subdivision and when I come in at night, I wake everyone up. So they said they would buy me the silencers if I would put them in.

Does anyone know of how much this is going to quiet my car? Is it worth it? This is what some website said...

"The APEXi N1 Super Silencer is to lower sound output from a high performance exhaust system without sacrificing high-end power. The APEXi N1 Super Silencer has also been shown to increase mid-range torque in some vehicles."

Any info would help!
