You can simply change out the rubber coupling pipes that go from the Supercharger to the charge pipe, charge pipe to the intercooler, intercooler to intake pipe, intake pipe on in. They are the couplings with a factory bulge in them. There are 4 and you can use harder pipe (I used radiator hose in 4 inch sections and it cost me 12 bucks and with an upgraded NST pulley I picked up an extra lb of boost and better throttle response.
