I myself have a S@B Filters CAI on my NBS 07 Crew. I can say it was an easy install and I would use one again on any other vehicle that I buy.I can also add that after the first tank of gas it did give me a few tenths morempg and I can feel the performance difference in the midrange. I am about to order my exhaust next and then add a custom tune.

 

Hey Fireguy, flowmaster has a new muffler out called the Super 44, baddest, loudest, mo fo out there. Check it out before you buy something. www.flowmastermufflers.com

 

yea i just purchased the S&B intake last night its on its way along with the TB spacer, so we will see what the increase actually is. as for the exhaust i havent ordered that yet i am waiting till my taxes come back. have you heard the new super 44's on an 07 5.3 yet?

 

Heres a clip I found of the super 44, its on a diffrent engine, but you get the general idea. http://www.youtube.com/watch?v=LWVneMkoM7U
