Just added Magnaflow catback systems. Nosiy enough but not obnoxious. Adding the new K&N aircharger system tomorrow. I am definitely enjoying this truck. I am a Truck Manager at a large midatlantic Chevy store and was tired of selling these to others for them to come back with big smiles. No I am having fun myself. Tinted front window 17% and rears on back with 5% (don't recommend you cant see a damn thing). Has anyone tries the K&n sys yet?

If a person did the E-Fan would that leave enough room for a spacer ?
Just a thought.

I have heard of using these spacers on other vehicles but like it has been said the stock fan would end up eating something if we added a spacer in stock form.

Yes I think there would be enough with an e-fan kit, especially the LS1 fans. But then the question of whether the spacer would in fact do anything would come up, most have been shown not to.

Since a Spacer will provide more air like a CAI, maybe it requires a tune to adjust for the change in conditions on our TBSS's? :undecided

Waste of $$, Tony. All it does is provide a minimal addition of plenum volume, of which the LS2-truck intake already has plenty....
