from my experience back when i raced my car. slidding a 2" pipe thru the cat allowed for more flow,im undecided about it right now,id like to keep emmisions stable,but im def going to ditch that waste of steel resonator.then id like to install a stainless muffler with a nice twin tip.reason being the resonator is rotted out. i plan on removing the res and muff and replacing muffler with a stainless one and a stainless tip.does anyone have loud exhaust on there benz??
