While the product is great, Auto Exhaust’s service is far and away the best I have experienced in a long time – A typo in their ad made this a tremendous bargain, one of those “too good to be true” deals, and actually, it was. The aforementioned typo was just that, but Auto Exhaust made it more than right – a pleasure to deal with. I would highly recommend this company highly as an honest, above-board organization, one of those thing so hard to find in today’s world.
