LOL ok, theres a member on the nation with Rob B hahaha
As for your exhaust any one of the vendors can help you, is there really any need for 5 inch ?? you can opt for the 4inch downpipe, but you'll have to play with it to get it right, being that its a tight fit as it is with a 3.5 down pipe, also most 4 inch turbo back arent true 4inch's. Kits ive seen and installed its a 3.5 inch down pipe and 3.5 piping to where the cab ends then it turns into a 4 inch pipe. 5 inch turbo back you'll get either a 3.5 down pipe to a 4 pipe then to a 5inch exit. 5 inch I believe gives you a better sound overall I believe. if anything get yourself a 4 inch turbo back with cat and muffler delete and you'll be happy.
4 inch is what i will go with just thought i would check prices. definetley want a truen 4 inch down pipe. i am going to put in a rcd egr delete and was going to get an exhaust so i might as well do it all at the same time. i have deleted the cat and have a walker btm right now but thought i would go a little bigger. getting ready to hit 50k on the miles so thought i would change a few things. i have a coolany filter installed and plan to do a flush when i do the egr delete as well. looking at getting sct to mix things up also.
