as part of my XS16v build im going to be fitting a set of throttle bodies, and if there anything like the carbs im running now i assume there going to be loud, as the car is going to be a sleeper i want it to be rather discrete and quiet,, if i were to fit the trumpets into a box and duct to an air box will that keep thing nice and quiet? or am i going to have to be a little more creative?   any advice welcome Cheers Paul.
