Gents,

Just purchased my new favorite toy for the family. A 2004 Yukon XL Denali. I've purchased a CAI and a Tune - should have them by the end of the week. I've been researching and alot of people I see have eFans and Corvette servos. Where is a good place to buy eFans and is there a thread on the installation? What exactly is the Corvette servo? Does it help performance at all? I'm also looking at upgrading the exhaust after Christmas - what do you guys recommend for this Denali XL, I don't want any drone (Magnaflow, Corsa, ect).

Love the site and wanted to get some more info before I start spending any more!!!

Or you can just get the 05 E/fans if you have a 34' radiator.

Hope that helps.

 

Thanks for the links. I think I'm gonna go with 05+ eFans as they should be a direct bolt on for my radiator. I see the Corvette Servo, but still don't know what it is used for, is this something I can install my self? Any opinions on the exhsust?
