I have a Borla Atak Muffler that I just put on my truck a month ago. It has one month of usage. Sounded great and loved it as a Cat-back system. I Decided to do long-tube headers with cat-delete and that muffler is just too loud with that setup. So I have replaced the muffler and am now selling just the muffler. I would like $200 for it, plus $20 shipping to anywhere in the USA.
