We have a guy who was going to make our flanges when we were going to make uppipes and he also made our maf sensor holders out of steal he could make you those flanges it will just be expensive if your only talking one (remember quantity makes things cheaper) probably 20-50 bucks since you want it stainless, stainless is not really needed the factory does not even use stainless on the uppipes and that sounds like a similar use that you need, plus stainless has a tendancy to crack after alot of heat... if you have the part already and you want another one send us yours and we have him copy it for you, but if you want one without having one allready send a perfect drawing with dimensions and all that good stuff.

Thanks, Jonathan @ BlowOff Racing
