I just wanted to drop you guys (and gals) a letter stating how much I appreciate your products. I just spent the afternoon taking a competitor's product off my truck because it did not work as claimed and in fact made my vehicle unpleasant to drive. I have several Banks items on my truck and they all have fit perfectly, worked as claimed and have never caused me a minute of dissatisfaction. I will always buy from your company in the future for any performance product related to my vehicle. Trust me when I say I just wasted $400 to learn that I should've stuck with a brand I know and trust. Keep up the good work.
