Just noticed that american muscle now sells borla xr-1 headers for the coyote. They are 1 3/4" primaries with 2 3/4 collectors and both o2 sensors are right next to each other in the picture. Would be nice to have an all borla setup but how much of a difference would be noticed with lets say 1 7/8" primaries and 3" collectors? I'm also curious if the borla headers mate up to the borla x pipe that comes with their cat back.
