What is a good aftermarket exhaust for a stock VX? A previous owner welded on a glass pack. It's now saturated and blown out. I sound like a Honda Civic's big brother coming down the street right now. I have absolutely no back pressure and crappy top end (a ton of low end torque though). A buddy of mine who works at a shop told me the cat is toast. I was thinking Flowmaster.. but wouldn't know what model fits the VX. Any suggestions? Gotta get this done asap, fairly inexpensive if possible. Thanks ahead of time.
