Sal,

The peak power gains looks a little higher than normal, so its possible there is a difference in how the car was strapped. I dont rule anything out. Our street x pipe removes the secondary cats as well has our own x section design, so its not just a cat delete only. Not sure how well you know our parts or not.



The gains for the majority of the powerband seem to be similar to another dyno done by a customer with our street x pipe at Active Autowerkes dyno. Here is the members original post link and the dyno below:
