Stock Exhaust Size
What's the stock size of the s2k exhaust, I see spugen sells their exhausts in 2.5" diameter, even though this is proven to gain some HP, what exactly happens to the torque, wouldn't it drop. Does anyone have pictures or sketches of the orginal exhaust in an s2k? Thanks, one more thing i just noticed, on the stock exhaust between the catalytic converter and the resonator there is this 1' pipe same diameter as exhaust, sticking out horizontally towards the drivers side as if to have the exhaust coming out from under the drivers door. What the hell is that? what purpose does it serve and what happens when it's removed. Thanks
