I would just like to say what a dream it was to install your products. The exhaust fit perfectly, and the instructions were very clear. I have airbag suspension for towing heavy trailers and I was worried about interference, however there was no problem. The Ram-Air intake was a breeze, and I think it is a huge improvement to the overall performance of the truck. I am a firm believer in getting what you pay for, and in the case of the Stinger system I think I got my moneys worth. Thank you very much Banks for your splendid products.
