Thought I'd give my experience with certain exhaust kits. I've installed MBRP on my LBZ and LML and have to say the fitment was shit for both. LML is my most recent MBRP install and nothing lined up right, hangers where all wrong and on top of it all the instructions they sent with it where for another kit forcing me to get online to make sure I have the right ones. After a week of having the MBRP system installed I ripped it back off and ordered the Flo pro kit. The flo pro came with the correct instructions, better clamps to ease in disassembly down the road, hangers matched up and are weld around the circumference instead of along the pipe, came with extra pipe sections to remove almost any need for measuring and cutting of pipe. So you know both kits are 5" Downpipe back no muffler. Yes MBRP was cheaper but in this case I got what I paid for a exhaust system that was junk and I wouldn't sell to my worst enemy. I'm sure some have had good luck with MBRP but flo pro will have my business from here on out. I hope this helps anyone trying to decide on which kit to purchase in the future.
