a custom intake question

[AaRoN]

hey guys. i was looking at my engine bay the other day. what i was thinking about doing was have some 4" exhaust pipe bent and drilled (for sensors) and use it for an intake. then attach a k&n filter. do you think it would work? go i safely go bigger than 4"?

most people use pvc pipe, but anything will work, i would keep at 4'' anything larger than that and itll lose velocity which will make it worthless.

id just do a PVC one you can paint it well and might look better?
