I purchased a Primary Muffler Delete Pipe to add to my G-Pipe (Secondary Muffler Delete) for a bump in sound about a month ago and it was just too loud and the drone inside the cabin became unbearable so I decided to try out a 14” L x 5” W resonator in line of the primary delete pipe (aka Cup Pipe). Overall, it significantly dropped the decibel levels. More than I expected actually. I’m happy with the install but I may opt for a Catalytic delete or a smaller 14” L x 4” Round body resonator to hear the difference in sound.
