Well I somewhat slightly misjudged the drop off at the end of a steep driveway today. I ended up with a nice deep fat dent in my h-pipe on both sides where they curve under the car. I have an exhaust shop that will make and install me to seperate pipes from the headers to my cat-back very cheaply. I figured I would have that done till I get around to buying a new h-pipe. Was never too thrilled about the fit and finish of my mac anyway. I know there will be a torque loss due to the exhaust pressue not being equal on both sides, but how much seat of the pants difference is there on a stock daily driver?
