Intake does make some noise but mounting an extra mufler on the already excisting exhaust system is doing more to lower the sondlevel than an insbox.

The 30xx 3 chamber exhaust were crap, no one is using them in the onroad although the 3036 I still have was a good exhaust. Now we have still the old 20xx type 3 chamber (with internal extra holes and larger holes) but some were taken off the list. There were some experiments with a small extra snap on silencer but no succes and now all eyes are focust on the new Hipex exhaust wich seems to have a dubble wall acting as a 4th chamber.
