Hey Jared, any .12 size exhaust flange will work with that motor and pipe, as long as it has the extra "lip" of rubber on the inside of it that matches up to the lip on the motor.... The ones that will NOT work well are the ones for a Picco motor, with no lip inside, or smooth... I f you are buying one in the T.C., Hub has ones that will work, the GS ones will work, or check Hobbytown... BTW Jared, this is Jeff, the guy you talked to the other day about maybe selling your car to, you can call me anytime if you need more help or advice, or if you wanna sell....
