    I wonder if you have or can easily have a look at your stock exhaust?

    While looking over the underside of my V Coupe, I noticed that the cross section of the left exhaust pipe is quite oval, while the right is circular. That is in the area immediately behind the flange where the pipe becomes parallel to the ground. The height of the left pipe section is about 1.7 inches while the right is about 2.5 inches, the pipe diameter.

    That really seems odd for a high performance system. Since the two sides are so symmetrical, I would expect the pipe dimensions to be very similar at each point. Further, I expect that symmetry was actually chosen to provide good back pressure balance over the operating range.

    How does your's look? I would really appreciate hearing.

    Good luck with your V. I have only driven mine for a couple of thousand miles so far - fun car!

    Regards,
