There is always a bottleneck, you may have reduced the severity of it, but there is always a most restrictive part of any exhaust system. It will be interesting to see if the gains up top are worth the decreased low volume velocity and subsequent loss of torque down low in the RPM range after the headers. Will certainly drive differently.
