Guys, you can not remove the rear cats and crossover and expect to pass your state emmission tests if you have one. Also the crossover is used to even out the exhaust pulses and by removing it you will loose a lot of low end rpm torque. We developed a kit that does away with most of the cabin heat when you are driving the car. In our test car with the top up we have had to turn down the ac as it froze us out. The only time you get heat build up with our system is when the car is parked for 1/2 an hour with the top up and the windows closed. Check out our system at the following link:
