im geting a rage unversal 3" back box, i know they are loud but do will they sap power away from the car or will i increase in bhp (even just a little)
i only ask as they are unversal so fit any car and are not specificaly designed for one car so may give different gains on different cars, and maybe even take power away on sum cars!
btw its for a 1.4sr 1.2 head, 1.3 manifold, 1.4sr cam (soon to be piper road/race cam, hopefully) with twin downpipes and middle silencer removed (strait through system)] with a pierburg 2e with larger jets.
cheers
