i agree about the cats,i noticed a big difference in the performance of my trucks when i put a straight pipe on it,i use to have the stock pipe with no muffler and no cats with a 4" tip.i didn't gain much better performance by putting in an after market air intake,i also gained 2 miles a gallon by doing the straight pipe and air intake.

you have to go turbo back... cat back systems are more for looks and sound, if you want a true change in performance, X the cats and get a 4 or 5 inch mandrel bent kit... MBRP is one of the easiest to install... looking at about an hour tops in the driveway..
i agree with what bnkrupt said about the turbo back exhuast,i ran 5" magnaflow on my 06 lbz and i wouldn't switch back to the 4".:fart :gearjamin
