Quieting duals


So one option is to put these cones in that are found in hushpower mufflers (don't know what they are called yet) that would go where the cats would have been. Another option is to to get different mufflers. The way it sits now it also has a drone on the freeway at cruising speed that is annoying on long drives. Any help is appreciated
otherwise i would say change mufflers.
longer bullets might help, summit sells some that are 24"
or i would go with magnaflow 4x9 mufflers. they quiet my cammed engine down ALOT.
minimal drone or interior resonance on the highway. i've heard catbacks that are much worse on stock engines.




When you say high flows you mean cats?
