Sup guys. I got a 5th Gen H22 and today I just installed my Vibrant Flat-Black Oval muffler with a 18" Vibrant Resonator. It's a little to loud for me. I'm thinkin it's about maybe between 100db's and 103db's. Dont get me wrong, it sounds nice, low and deep, not raspy at all but just a little bit to loud. I just want to bring down the noise a little bit. I thought with the 18" resonator was gonna be a little more quiet Should I put a 22" resonator? or what could i do? Any input would be great!! By the way, I have 2.25 piping with stock headers and stock cat!!

 

try out the 22" resonator only way your going to possibly reduce the noise. other then simply getting a different muffler. IF you do go that route pm with how much you want to sell the 18" resonator.
