trick flow vs gt40 intake?

Its pretty straight forward as far as the install goes. I personally think the Street heat is better for the fact that if you upgrade your heads and whatnot and need more flow, you dont have to buy a whole new intake manifold, you can just buy a track heat upper, but both are good intakes.
 
The GT40 intake upper and lower out flows the TF up to around 5,000 RPM but past that the TF takes over, so i would sugest if running a N/A setup go with the GT40 but if your adding a turbo,supercharger, or nitrous then go with the TF.
