Message	I noticed a slight hissing sound when I step on the gas pedal coming from the front of the car after I installed the downpipes. It almost sounds like a blowoff valve and goes away as soon as the engines rpm goes back down. Is that the turbos possibly? Did the precats muffle that sound that much? I checked all the gaskets and bolts and everything is tight.
