"I love my 2006 F150 XLT. It's got the 5.4l Triton. I put a flowmaster 40 series delta flow muffler and an AEM Brute Force intake, on it and it sounds better than anything i've ever heard. The interior is the best i have seen in any new vehicles. I have not had any problems with the truck. Passing people on the freeway is so easy with the 300 hp. Once again BEST TRUCK EVER!"
