We are using the stock G35 rear end and have partnered with a drive shaft shop to make a drive shaft that can adapt to the getrag from the supra to the G35 diff so everything there still works like factory. We did keep the stock braking system since we already had the Brembo package on this car, so no modifications were made to the ABS which still works. As far as emissions goes the 2JZ is a very efficent engine and we actually got a little over 30 MPG on a test drive we took last weekend going over 300 miles on the highway. We do atribute that MPG gain to the heat exchanger which allowed us to tune the AFC to -30% fuel hence the lowered fuel consumption. The 30 MPG was with us hitting boost on the highway so we could tune the AFC properly. Once you get past the engine we do have a 3 inch exhaust, but it has a Y pipe that adapts back into the stock G35 exhaust on one side and the other side is a 3 inch adjustable exhaust cut out so we can open, close, and adjust the exhaust. The cut out also helps us restrict the exhaust sound down to almost a stock level when just cruising around. We are in Florida so we don't have emissions check like some other states, but we are confident that it should meet emissions the way it is set up currently. On a side note we wanted to adapt back the stock functionality of the G35 so much that we even made the Supra 6 speed getrag transmission adapt so that the stock motion normally used with a 6 speed getrag of pulling up to reverse has now been adapted so you push down for reverse just like a stock 6 speed G35 does.

Thanks for the questions.
