3inch single exit exhaust too big for N/A

dual 3" WILL lose you low end torque. back ressure creates torque. sure u might gain slight hp up top but the butt dyno will feel like there is less power because of the torque loss.

and before anyone asks "how do u know if a 3" will lose power? have u tried it?"... well no i havent, but i understand how cars work...

You sound EXACTLY - like word for word - like everyone used to on the 8thcivic forums. "We need backpressure or we'll lose power down low". That was the mantra for at least 2-3 years. Everyone chanted it. One day a 3" comes out, proves every single person wrong.

Maybe you are right, maybe your'e wrong. Someone should actually test it before saying that, though, because everyone used to be like you until it was proven wrong.

Dont mean to sound like a jerk, but ur only partially correct. I made 330whp 270wtrq with my Amuse R1 Titan Extra. Swapped to Tomei Expreme Ti with same mods on car, made 330whp/270wtrq, same exact numbers. 270 peak trq @ 3000rpms and actually carries the trq curves higher and longer through the revs than the Amuse dual exhaust did. High revving cars dont want any back pressure, trq is measured on how fast exhaust gas leaves the cylinder, you want straight flow no back pressure or turbulence from flanges or bends. If anything, trq is sustained better through the revs and hp curve seemed to drop up top, but peak numbers were both same. Strange i know, EcuTek and DynoJet do not lie.
