I looked for a while now and I noticed that MBRP does not make turbo backs in 4" for the 06 dodge 5.9, they all come in CAT BACK. So I need to know which make has 4" systems in turbo back? I was thinking about buying the MBRP cat back and then buying an after market 4" down pipe from which ever make but those down pipes are pricey!
