I just got a new Ford Motorsports driveshaft. It is much larger in diameter than the stock one I was running. I already knew I needed to replace the Flowmasters I was running because with the 76mm Hellion Kit I was told not to run chambered mufflers plus it is just to loud. They just barely fit under the car with the smaller driveshaft. I am sure they would rub the new one. What mufflers should I consider to work well with the turbo, quite the car down under mormal throttle conditions, and fit under the car with the larger driveshaft ? :shrug:
