WE HAVE TIPS FOR JUST ABOUT EVERY APPLICATION, IF YOU WANT TO REPLACE JUST THE TIP ON A STOCK FORD OR GM THE 3.5" INLET TIPS MAY WORK BEST, THE 2003+ DODGES ARE TYPICALLY 4", WE HAVE TIPS FROM 3.5" INLET SIZE TO 6" INLETS. STAINLESS, BLACK CHROME, BLACK POWDER COATED TIPS, ROLLED EDGE, ANGLE, PENCIL TIP, DOUBLE WALL, RESONATED, WE EVEN HAVE TIPS THAT HAVE TEETH AND SOME AS LARGE AS 12" IN DIAMETER, JUST KEEP IN MIND CLEARANCE AND HOW FAR UNDER THE TRUCK THE TIP WILL BE. I LIKE TO DROP A STRING LINE ON THE FENDER AND LINE IT UP SO THAT IS ALL THE FURTHER IT EXTENDS, BUT THAT IS WHY WE OFFER SO MANY TIPS, EVERYONE LIKE SOMETHING DIFFERENT.
