My nieghbor is really looking hard to get a new truck but always likes to change the exhaust and do something simple like a Banks system to boost the power. Problem is all he has heard so far is NO! Is this true. He just sold his 06 crew cab 6. 0 that would run 14. 95 @ 91 here in Denver with just a Banks module and 5" exhaust. Liked it a lot but he is leary of the new 6. 4.
