Just installed my SP o/r longtubes last week, and the setup is now incredibly raspy through the entire RPM range instead of just mid-range under mild load with just the mufflers and midpipe. Any suggestions on how to fix this without installing cats? Most of the reason I wanted headers was to eliminate my cats, and am trying to find a rasp-free exhaust setup without adding cats to my exhaust.
