i for one had the shiny fart pipe loud as hell on my civic, till i got pulled by the local pig convention. lesson learned. so what did i do? i threw on a cheap dyno max chambered muffler (which quieted it down), rattle canned it flat black, and just added an exhaust cutout for "spirited driving" right after the header before the resonator. i havent been fucked with a cop for exhaust since. its been 4 years already. if youve got a shiny or modified looking exhaust, your gonna get fucked with. no matter how quiet it is. if it looks and sounds factory OEMish your fine.
