now what our fellow pakwheeler (soul_hakker) is trying to know about is something very ordinary yet overrated and hyped by the exhaust fabricators of Peshawar with claims of extra horsepower by the addition of this nifty object .
"VTEC BOX" a.k.a "VTAK dabba" (as known in our street lingo/jargon)
is the resonator unit made by the SANKEI company for the OEM 95-05 Honda cars (mostly civics)
now this thing in installed in all forms of slush boxes and econo trolleys coupled with a free flowing exhaust system (to reduce the throaty exhaust note)
and claims to give as much as 5hp (ridiculous) lol
thank you.
