3" rubber coupling (had a metal sheet around it that the 2 clamps were mounted to. i pulled the metal sheet off and used the clamps), 3"- 45 degree "street pipe" elbow (I say street pipe bc that's what the label at Menards said). it is 3" outer diameter on one end and 3" inner on the other side, 4" K&N filter (you can choose whatever filter you want). the 4" filter mounts perfectly over the 3" inner diameter end. Drilled a 1/2" hole for the sensor and then used a 1/2" rubber grommet and silicone adhesive to seal the hole around the sensor. then just used high temp gloss black paint to paint it. Sorry this may be a bit confusing. If you need me to, I'll be glad to roll down to menards and take pics of the exact parts I used to make it easy on you man.Originally Posted by Schmidty
