I have a 2003 Harley F150 and my mechanic said I have a bad cat so I am looking to replace my midpipe with something louder. I was told that the Lightning's and the Harley F150's use the same midpipes so please correct me if I am wrong before I buy something that I can not use. I am thinking of going with something that is either catless or has high flow cats that will make the truck louder with the stock catback still in place. It will be shipped to 11780. Let me know what you have. Thanks.
