" The exhaust system of my car don't have resonators. It has 3x straight through mufflers, which has the same flow concept of the resonators but with much more capacity of insulation wool for better sound dampening.
See a pic of the full system on my post #18
on first page.
Like i said before, i ran for a month just with the first muffler. Very agressive and sporty sound without any drone issues. It turned heads around, in a good way. Then i decided to put one muffler on the end of each rear pipe to quiet down a bit the tone, just because it is my DD car. "
