According to CORSA Performance the system is good for about 20 hp at redline. Nothing up to around 3500 or so, as in any other intake/exhaust work. Right now I believe the system goes for around $1300+ online. It's all stainless and carries a lifetime guarantee. Easy to install, with a frame lift.
Low, rumbly idle, quiet midrange and dead quiet cruise, stick your foot in it and wake the dead. It's essentially a tuned straight pipe - a good flashlight will shine from the cat to the tip. It will give you a tad of extra gas mileage on extended highway trips - nothing in everyday commuter driving. Yes, it's worth it. No, it is not a ricer fart-can bolt-on. Always remember: More noise DOES NOT = more power.
