"the only thing you can really expect is to lose some low-end torque. All it will really do is make your car louder."
WHAT??
You may lost some low end torque, but I'd seriously doubt you'd be able to feel it. The gain in horsepower in the upper RPMs will more than make up for it! You are removing 4 constrictive catalytic converters...you are going to feel an improvement, and definitely hear it!
