I just wanted to take a minute and recognize a business with great customer support and that stands by their product as it rarely happens any more. I recently had my Aero Turbine muffler fail on me so I contacted Aero Exhaust to ask what could be done. Even though I thought I had a "lifetime" guarantee it had been eight years since I bought the muffler and has no proof and couldn't even remember the name of the truck shop that I bought it at. All Jordan at Aero Exhaust asked for was a pic showing the damage and an inquiry as to how I could have destroyed it to such a degree. Within a week I had another new muffler sitting on my door step when I got home from work. I really love the way this muffler makes my truck sound and I hated the stock muffler that I had to use as a replacement. Great Job Jordan and thanks for standing by your product!!
