Vararam questions?

[93 svt]

My intake and exhaust should be in today and like most of you want to install it right away. Anything special the Vararam needs to be installed. i heard I might have to mess with the radiator is this true? anything else I should know. Thanks

I am looking at getting the Vararam intake but am concerned about changing the sound of the car. Does it make noticable changes in the cabin? My goal is to increase performance as much as I can without making it louder during normal driving.

There will be a sound increase with ANY intake system due to silencers and baffles that are in the factory system no longer being there.
