Hello everyone. I am new to the forum and just had a few questions to ask. I recently purchased a 2014 Dodge Ram 1500 express crew cab. I wanted to go with either a 24 or 26" KMC Slide rim with a low profile tire. My question is would I have problems with my front or rear end if I go with this size? Also will it void my lifetime warranty. Also , if I go with a magnaflow or flowmaster muffler , will it void warranty? Thanks to all that reply!
