i went to the N/A DSM website then under the mods section there is the instructions to cut your stock air canister and to remove the intake silencer(didnt know there was one!!) but i took the MAF from the can lid and removed the paper silencer w/useless metal holder and wow the car really revs more freely, (sorry no HP here) but does sound a little better too!! just thought id share!! note: this is for the non turbo!!!
