hmmmm......let's see ...... it looks like the resonated mid pipes are about the same ...... or are they .. ??

If so, that just leaves the muffler being the sole difference.

According to the below graph, as best as I can read it, the Perrin system should allow the engine to develop more torque all along the power band (with the exception of that one little peak and a slight edge in the torque dip).

So, what's going on with you and your car .... ??
