I had a pypes O/R H with muffler deletes. It sounded like poo, but loud. I added a set of magnaflow resonators right after the H pipe, that mellowed it down a bit, but once you get in it, holy shit its loud. Loud here meaning that if you are outside the car it makes your ears hurt and itch a little. I am getting rid of the muffler deletes and putting my flows back on.
Happy new year all.
