Does anyone know the outside diameter of the throttle body on the MSP? I'm making my own hardpipes and need to know what size silicone reducer I need to use. Is it 2.5" ? Thats just a guesstimate, someone help me out here.

You will need to use a 2.5" coupler.

Damnit Shawn, you're to full of useful information. Thanks again man, you're alot of help!
 
Just make sure you get a 90deg silicone hose not straight. If you don't get a bent hose you'll have more work making that pipe that goes from the throttle body to the intercooler because of the way the TB opening is positioned. Good luck and have fun!
