This is not always the case. Our straight through CBE with high flow cats or test pipes has no rasp. We only notice a little with this configuration and our long tube headers.
Now he stated in the first post that he wants to leave the aftermarket cats on the car. Those combined with our straight through CBE will have zero rasp.
